In recent years, advancements in drone technology have revolutionized various industries, from agriculture to search and rescue operations. Among these innovations, thermal imaging drones have emerged as a game-changer, offering unparalleled capabilities in a wide range of applications. In this article, we delve into the fascinating world of thermal imaging drones, exploring their uses, benefits, and the transformative impact they have on diverse fields.

Understanding Thermal Imaging Technology

At the heart of thermal imaging drones lies sophisticated infrared (IR) sensors capable of detecting and measuring heat emitted by objects. Unlike traditional cameras, which rely on visible light to capture images, thermal cameras detect infrared radiation, allowing them to visualize temperature variations across surfaces. This ability to "see" heat signatures makes thermal imaging drones invaluable tools for a myriad of tasks, especially in environments where visibility is compromised or where traditional methods fall short.

Applications Across Industries

The versatility of thermal imaging drones transcends industry boundaries, finding applications in fields such as:

1. Search and Rescue:

In emergency situations, every second counts. Thermal imaging drones Autel EVO II 640T V3 equipped with infrared cameras can swiftly locate missing persons or detect heat signatures in disaster zones, even in low-light conditions or dense vegetation. Their ability to detect body heat makes them indispensable tools for first responders, significantly expediting search and rescue operations and improving outcomes.

2. Precision Agriculture:

Optimizing crop yield and monitoring plant health are paramount in modern agriculture. Thermal imaging drones provide farmers with invaluable insights into crop vigor, irrigation efficiency, and pest infestations. By detecting temperature differentials across fields, farmers can identify areas requiring intervention, such as irrigation adjustments or pest control measures, thereby maximizing productivity while minimizing resource usage.

3. Building Inspections:

Traditional methods of building inspections often involve manual labor and pose safety risks. Thermal imaging drones offer a safer, more efficient alternative by enabling inspectors to identify structural anomalies, insulation deficiencies, and moisture intrusion remotely. By detecting temperature variations indicative of potential issues, such as water leaks or electrical hotspots, thermal imaging drones facilitate proactive maintenance and prevent costly damage.

4. Wildlife Conservation:

Monitoring wildlife populations and combatting poaching are ongoing challenges for conservationists. At the same time, thermal imaging drones can be used to monitor the number and living habits of wild species and provide assistance for hunting wild boars, elk, coyotes, etc. Thermal imaging drone hunting has also become a pastime for most families in the United States.

Our knowledge of physics tells us that we do require air (or "fluid" as they say in physics) to fly drones.
But what if it was possible to take a drone's air with it into outer space ? How ? By fitting an air-tight enclosure around the drone.
Ok ... wait ... physics will have something to say about that too! ... it won't fly! ... Net zero force
Newton's 3rd law will prohibit it ... and yes that is true ... if we constrain our minds with current flight machines designs.

... ok explain ...

What if it was possible to come up with a new drone propulsion design ... one that bend (or curve) the ejected propeller air, all the time!
Would that imply that the ejected air will never form a jet stream and will lose it's kinetic energy quickly ?

Ok, say that could work, but how would the re-action forces on the drone be used so that the drone can move in a pre-determined direction ( be controlled ) ?
The answer for that is also given by physics ... vectors with a resultant vector.
Ok, surely you will need more than vectors ?
Yes, add some some Arduino wizardry - 1 or 2 very unique algorithms - together with an IMU ( like a Bosch BNO055), plus a few other parts ...
and you have an outward spinning drone! What is an outward spinning drone ?

                The Droverbot

Propelling any vehicle in a pre-determined direction while the entire vehicle continues to rotate (outward spinning) is a groundbreaking innovation in propulsion.
With current mainstream propulsion vehicles, the engines (or motors) provide thrust via the axle in a hub,
e.g. car wheels with an axle at the centre, for propellers with an axle at the centre.
But with the experimental drone above, the thrusters are located on the spokes and rim of the octagon frame.

This propulsion system have distinct characteristics that can be exploited, with huge potential as explored in this post.


Ok, but the droverbot drone is not flying as shown above. Why ?
There are several reasons why I chosed to propel the experimental drone horizontal and not vertical, but it is a story for another time.

But just to indicate how vertical flight might work, please click the link below for another video, it is an early 2D simulation I’ve build a few years
ago which shows just that

               Vertical Flight Simulation

The 2D simulator software I used, only had rocket thrusters for propulsion, which would've been a limiting factor if
this simulation had to be build in the real world, with the forces shown in the simulation.

However, it does illustrate how an outward spinning object perform vertical flight.
The Droverbot (shown in the first video) method of propulsion is far more matured, versatile and capable of vertical flight as shown in this early simulation.
(See the Whitepaper in the link, further down below to understand the drone’s method of propulsion.)



Key aspects of this experimental drone (or “droverbot”) that set it apart.

• This drone has the ability to propel in a straight line in a predetermined direction while the entire drone (including its thrusters) is rotating continuously.
• The continuous rotation of the entire drone creates an interesting phenomenon where the air is distributed once it leaves the propeller blades,
  resulting from the entire drone's rotating motion.
• Powered by 8 brushless motors and propellers, this drone exhibits both linear and rotational motion.
  Four motors managing linear motion and four rotational motion.
• Modular in design, this drone can be scaled up by adding more drones to a common platform, creating larger drones that can be further scaled,
  only limited by practicality.
  The central hub of the drone (centroid) allows for an axle to be fitted, providing the flexibility and versatility to scale.

Key Properties

• The reaction forces generated by the motor-propellers on the drone due to ejected air (action forces) are harnessed as vectors in
  such a way that they cause a consistent resultant vector. The resultant vector (direction and force) can be chosen and adjusted as needed.
• Since air is distributed behind motor-propellers continuously, it is not reinforced with additional ejected air,
  leading to quicker weakening of the kinetic energy of the ejected air compared to other propulsion systems
  where ejected air is continuously reinforced (e.g. jet streams behind an airplane’s propellers).
• This experimental drone, as shown in the video, can propel along a horizontal plane.
  With further development, the drone can be orientated vertically and should be able to propel upward into the atmosphere.
  Each drone is capable of propelling along one plane, and when multiple drones are combined, they can move in any direction in three-dimensional space.
  Individual drones can be connected modularly to a common frame by attaching an axle to each drone hub at its centroid.

Implications

• The drone's resultant vector can be directed to any degree within 360 degrees. Direction and force can be adjusted as needed.
  In a multi-drone vehicle, the combined vectors of the drones enable flexible manoeuvring in three-dimensional space.
• Since there is no reinforced ejected jet stream (as mentioned earlier) and weak kinetic energy that dissipate rapidly when air molecules collide
  with other air molecules at rest, it is feasible to assume that an enclosure (with a sufficient air cushion between propellers and wall) can
  be added around the drone.
  
  Adding an enclosure will have several key implications:
  
  
  • Below follow a few implications when propelling earth-based:
    
    
    • An enclosure will solve the problem of dust and debris kicking up from propeller-engines at low altitudes.
    • Unlike rockets with fixed cylinder shapes, an enclosed vehicle with rapid directional changes and
      flexible design shapes will not be limited by high-altitude winds, ensuring flights are not cancelled.
    • The risk of objects (or debris) colliding with propellers will be eliminated with an enclosure.
    • An enclosure will significantly reduce noise pollution caused by conventional airplane propellers.
    • The risk of losing parts will also be eliminated by an enclosure.
    • Taking all of the above into account, the automotive industry should be able to build "real" – flying cars.
  • An air-tight enclosure will enable drones to fly in outer space without requiring an atmosphere.
  • An air-tight enclosure will ensure that all propellant (air) is re-used. Since air does not contain energy,
    the energy source when earth-based, can be battery powered.
    
    When in outer space, the energy source could be a small nuclear reactor (e.g. “Kilopower” reactor as build by NASA).
    
    This have the potential to reduce the mass to 10% or less of the vehicle's total mass compared to rockets where
    propellant (with integrated chemical energy source) is over 90% of the vehicle’s total mass.
    
    With unlimited propellant (re-usable) and long-term energy sources like nuclear re-actors, long-term trips in the solar system and potentially,
    even interstellar travel to neighboring stars becomes feasible from a propulsion system point of view.
    
    
    You might wonder if Newton's third law will be upheld when a drone is enclosed.
    
    With conventional propeller-engine thrusters, this is impossible due to the reinforced ejected jet stream (action force) that is equal
    in strength to the reaction force on the vehicle, in the opposite direction. This results in a net zero force.
    
    However, with this experimental drone, there is no reinforced, ejected jet stream in the opposite direction.
    Instead, due to its continuous rotation, the ejected air is not reinforced by more air, but is distributed.
    
    
    So, how does Newton's third law apply then?
    
    At a moment (fraction of a second) of air ejection, Newton's third law is applicable, but since the ejected air is not reinforced by the next moment of air ejection
    (which is ejected at a different degree as the drone rotates), no ejected air jet stream is created (in the opposite direction) as with conventional aircraft.
    
    However, the sum of the distributed air (action force) still equals the sum of the reaction force on the vehicle. Newton's third law is upheld.
    Since multiple drones can be attached to a large platform, which can take any shape (limited only by practicality), various types of vehicles can be built.
    This is not limited to vehicles but could result in large upper atmospheric platforms (even in the atmospheres of other planets) or even platforms in space.

Next steps

This experimental drone is the starting point, marking the transition from zero to one, for a new type of vehicle. Alot of work will still need to be done
to make this a reality.

To unlock its full potential, it will require a collective effort from a community. This could be a revolutionary innovative project if a community decides so.
My hope is that a community will come together around this project to build upon this effort

Please leave a comment below on your thoughts.

Here is a preliminary high-level plan of the next steps that are needed.

High-Level Action Plan

1. Redesign Drone Frame
The current octagon drone frame requires an overhaul, as it was originally designed to host 16 motors for testing various permutations.
The focus should be on creating a lightweight octagon shape frame that is both structurally reinforced and sized appropriately to withstand forces at play.

2. The source code
The source code needs tidying up and rewriting to accommodate improved algorithms for linear and rotational motion,
as well as integrating the list of permutations to control propulsion in different directions.
This also includes expanding the list of permutations on how the 8 motors can be applied together for vertical flight, and multi-vehicle drone configurations.
As development advances, the codebase have the potential to expand to cater for multi-drones, underwater propulsion, space flight, acceleration and
deceleration in different mediums, and much more.

3. Electronic Components
The drone is constructed using consumer-grade electronics on top of the Arduino platform. Each component requires review and replacement if a better component
can be found that will enhance its versatility in creating a more advanced drone.
For example, the current IMU (Bosch BNO055) has limitations with its magnetometer. Additionally, a GPS should be added and better remote-control radio for starters.

4.Multi-drone
Once vertical tests flights are successful, several drones can then be attached to a central frame, and a single flight control computer will manage them all together.
This will enable the vehicle to move in any direction in 3D space.

5. Enclosure
At the same time (or afterward), a super lightweight, air-tight enclosure will be built to fit around individual drones or the multi-drone vehicle.

When this test succeeds, space travel will become a reality for drones. Enclosed air (as a propellant) will be reused with only the energy source that could deplete.
This will result in the ultimate reusable vehicle. This have the potential to revolutionize transportation and spaceflight forever.

6. Undersea Maneuvers
By modifying the existing design for submerged propulsion, trials can be performed below the surface, replacing air (a fluid) with water.

In Conclusion

I've been working on this project in my spare time for a very long time, and it's now at a stage where I believe the fundamental technology has been develop that can be built upon.
With a community involved, progress can be faster and who knows where this effort can go!

I want to thank God Almighty for carrying me over the years to continue, for my family supporting me.
It would have been impossible to get to this point without them.

How can BVLOS drone operations be conducted in Europe, especially using a drone docking station? When it comes to flying drones in Europe, understanding the regulations and its entire architecture is important. The European Union Aviation Safety Agency (EASA) oversees the regulations across 27 European Union Countries and 4 others including Iceland, Liechtenstein, Norway, and Switzerland to ensure safe and standardized drone operations.

Recently, we conducted a webinar featuring Matteo Natale, Technical Standards Manager at DJI, focusing on breaking down EU drone regulations, right from the fundamentals to dock operations, while shedding light on the key components that drone operators need to understand.

‍

‍

Classification of drone operations

The European airspace categorizes aerial operations into three main types. The regulation in Europe follows the concept of proportionality. These categories are tailored based on the level of risk associated with different drone operations. This regulatory framework applies to both, commercial and non-commercial operations.

 

Regulatory framework

Open category
The Open category pertains to low-risk aerial operations with minimal involvement from authorities. However, there are several technical restrictions and flight limitations to consider. Operators simply need to register their drones, check state insurance requirements, and fly within the operational limits set by the subcategory. The manufacturer, who needs to provide drones with a class identification label, handles any technical restrictions. However, these operations are limited to Visual Line of Sight (VLOS) only and cannot be used for Beyond Visual Line of Sight (BVLOS) flights. 

‍

In this category, the drones are restricted to a maximum altitude of 120 meters above ground level and can weigh no more than 25 kilograms. The Open category is further divided into subcategories A1, A2, and A3.-- which may be summarized as follows:

‍

A1: fly over people but not over assemblies of people 

A2: fly close to people

A3: fly far from people

‍

‍

Specific category

The Specific category involves a higher level of involvement from authorities. Unlike the Open category, drones in the Specific category can fly Beyond Visual Line of Sight (BVLOS), above 120 meters in altitude, and weigh more than 25 kilograms. Generally, commercial drone operations utilizing docking stations to automate flight operations fall under this category. Operators need to seek operational authorization from the National Aviation Authority (NAA) through the following approvals:

‍

SORA: It is a risk assessment methodology for drone flights in a specific category that aids in classifying risks, identifying mitigations, and setting safety objectives. SORA helps establish operational limitations, training goals, technical requirements, and operational procedures.

PDRA: The Predefined Risk Assessment (PDRA) is an operational scenario for which EASA has already carried out the risk assessment and has been published as an acceptable means of compliance.

‍

STS: STS is a predefined operation described in EU regulations. An operator is not required to obtain operational authorization to conduct an operation covered by a STS. Two STSs have been published so far:

• STS 01 – VLOS over a controlled ground area in a populated environment;
• STS 02 – BVLOS with Airspace Observers over a controlled.

‍

LUC: Light Unmanned Operator Certificate (LUC) is an optional certification that grants privileges, such as starting operations in a specific category without requiring operational authorization. Operators can voluntarily request an assessment from their NAA to evaluate their capability to assess operational risks.

‍

Certified category
The Certified category is designated as high-risk and operates under a regulatory framework akin to crewed aviation. This category applies to operations involving elevated risks such as transporting passengers, carrying dangerous goods, and flying over assemblies of people with drones positioned above three meters.

‍

Understanding Class Identification Label

According to EU regulations, Uncrewed Aircraft Systems (UAS) are classified into seven distinct categories known as Class Identification Labels. The specifications and physical characteristics of the drone are what determine its classification. These labels range from C0 to C6, with drones in the C0 class weighing less than 250 grams and those in the C6 class weighing less than 25 kilograms. They apply to both the open and specific categories.

‍

Following are the technical requirements and limitations for all class-labeled drones:

‍

These labels provide clarity for drone operators and regulatory authorities alike. They ensure that drones are appropriately matched with the level of risk associated with their operation. By categorizing drones into specific classes, the regulations have been tailored to address the varying levels of risk posed by different types of drones. This approach promotes safety, accountability, and standardization across the drone industry.

‍

The specific category includes class labels C5 and C6. They require the implementation of a geocaging system, enabling remote pilots to establish a virtual perimeter and a programmable boundary for their operations. Additionally, a flight termination system (FTS) must be available for emergencies.

‍

Obtaining operational approvals for the Specific category operations

The Specific category encompasses a wide range of activities, from commercial endeavors to specialized missions that require a higher level of involvement from regulatory authorities. To ensure compliance and safety, operators must undergo a rigorous process of obtaining approvals. By understanding and following these steps, operators can navigate the complexities of the Specific category.

1. Concept of Operations (ConOps): In the drone industry, ConOps outlines how drone systems are used in specific operational environments. It details the roles of drones, user responsibilities, various flight and mission scenarios, as well as maintenance and support protocols, guiding stakeholders through the development, implementation, and usage stages.
   
   
2. Risk Assessment: This assessment helps evaluate potential hazards and assesses the level of risk associated with the proposed drone operation. These assessments could be in the form of Specific Operations Risk Assessment (SORA), Predefined Risk Assessment (PDRA),  Standard Scenario (STS), or Light UAS Operator Certificate (LUC), as mentioned above.
   
   
3. Training: Operators should undergo specific training to demonstrate proficiency in operating drones within the Specific category. These training sessions could cover topics such as flight planning, emergency response, and compliance with regulations. Training ensures that operators have the necessary skills and knowledge to conduct operations safely and effectively.
   
   
4. Approvals: The national aviation authorities evaluate the proposed ConOps and if all the requirements regarding mitigating potential risks are met, they grant approval for the operation to proceed.
   
   
5. Flight: Once the approvals are completed one can conduct the drone operations.

‍

Understanding the Specific Operations Risk Assessment (SORA) in detail

According to EASA “SORA is a methodology for the classification of the risk posed by a drone flight in the specific category of operations and for the identification of mitigations and of the safety objectives.” The following 10 steps explain the process of obtaining the SORA approval.
‍

1. Concept of Operations (ConOps): Presenting an organization's system and operations to relevant authorities for approval.

‍

2. Intrinsic Ground Risk Class (GRC): Determining inherent ground risk based on factors like the presence of people or buildings.

‍

3. Final Ground Risk Class (GRC): Assessing ground risk after implementing mitigations to address potential hazards.

‍

4. Initial Air Risk Class (ARC): Evaluating air risk factors before each operation, such as airspace congestion or weather conditions.

‍

5. Strategic Air Risk Mitigations: Applying pre-flight measures to mitigate air risk, like ensuring drones are weather-resistant.

‍

6. Tactical Air Risk Mitigations: Implementing in-flight measures, such as automatic hover or return-home programming.

‍

7. Final Specific Assurance and Integrity Level (SAIL): Determining the overall safety level by combining ground and air risk assessments.

‍

8. Operational Safety Objectives (OSOs): Identifying specific safety objectives based on the organization's SAIL.

‍

9. Adjacent Area and Airspace Considerations: Developing strategies to mitigate risks of encroachment on nearby airspace or ground areas during operations.

‍

10. Comprehensive Safety Portfolio: Compiling all assessment results into detailed safety documentation.

‍

SORA categorizes the risk of an operation into six levels, denoted as SAIL levels, ranging from I to VI. This classification is derived from a comprehensive evaluation that combines both Ground Risk and Air Risk factors. Each SAIL level corresponds to specific requirements that operators must adhere to, meticulously tailored to mitigate the identified risks inherent to the operation. By employing SORA, operators can effectively evaluate and manage the risk landscape associated with their drone operations, ensuring safety and regulatory compliance across the board.

The BetaFPV Pavo35 represents the pinnacle of the Pavo cinewhoop lineup, bringing to the table a blend of power and versatility that distinguishes it in the crowded FPV drone market. Engineered with a solid build and larger propellers, this drone is tailored for more challenging cinematography requirements. I have also used other fpv motor. What kv motor would you like? 22000KV brushless motor or 1800kv brushless motor? You can see the drone motor size chart here. 

Beyond a Mere Size Upgrade: Pavo35 vs. Pavo25 V2

At first glance, the Pavo35 may seem like a scaled-up version of the Pavo25 V2, sharing many hardware similarities. However, it's designed to cater to distinct flight styles and requirements. The primary distinctions lie in the frame, propeller, and motor sizes, with the battery connector's positioning also differing; the Pavo35 sports an XT60 connector at the front, while the Pavo25 V2 features an XT30 at the rear.

Specifications Breakdown

PAVO25 v2: The Nimble 4S Contender

• Wheelbase: 112mm
• Motors: 1505 4600kv
• Weight: 153g (excluding FPV battery)
• Flight Time: Approximately 6-8 minutes
• Camera Compatibility: Supports lighter action cameras such as the Naked GoPro series, Insta360 Go 2/3, Caddx Peanut, and Runcam Thumb Pro.

PAVO35: A Powerhouse of Versatility

• Wheelbase: 148mm
• Motors: 2006 2400kv
• Weight: 238g (dry)

• COB LED light strips for visibility and aesthetics.
• Choice of ExpressLRS or TBS receivers.
• High thrust-to-weight ratios for dynamic flight.
• Y-shaped CNC metal support enhancing structural integrity.

Craftsmanship and Construction

The Pavo35, weighing in at around 274g with an ELRS receiver and DJI O3, showcases a lighter frame than its counterpart, the GepRC Cinelog35. It boasts a sleeker battery strap and a more discreet antenna setup. Despite its durability, highlighted by a 3mm top plate and substantial prop guards, the placement of the XT60 connector raises concerns due to its vulnerability to shorts from environmental debris.

Key Components and Performance

Utilizing the same FC/ESC board as the Pavo25 V2, the Pavo35 is equipped with an F722 35A AIO V2 flight controller. This setup is complemented by 2006 2400KV motors and Gemfan D90S three-blade propellers, striking a balance between power and weight for agile flying and the capacity to carry heavier cameras.

One critique pertains to the battery mounting system. The fixed strap position, combined with a front-heavy camera setup, can adversely affect performance by making the drone front-heavy.

DJI O3 Installation Process

Integrating the DJI O3 Air Unit is straightforward, thanks to a plug-and-play connection. However, accessing the micro SD card and USB-C port can be challenging due to the air duct design.

The Flying Experience

Recommended with 6S 1100 to 1500mAh batteries, the Pavo35 promises exhilarating high-speed flights. Yet, its real-world efficiency and flight duration fall slightly short of expectations, especially when compared to competitors like the Speedybee Bee35. Nonetheless, its prowess in both indoor and outdoor settings is noteworthy, particularly for capturing dynamic outdoor activities.

Setup and Configuration

Accessing the micro USB connector for setup might require finesse due to its concealed placement. BetaFPV has pre-configured many settings, leaving minimal adjustments needed for personalization.

Concluding Thoughts

The BetaFPV PAVO35 emerges as a formidable 6S cinewhoop, adept at supporting full-sized GoPro cameras while delivering remarkable speed and agility. Though it might seem as a straightforward enlargement of the Pavo25 V2, its flight performance speaks volumes. Despite some design and configuration quirks, it stands as a competitive option for those seeking a versatile and dynamic cinewhoop. Additionally, I  have aldo uesd meps 1404, 2408 Brushless Motor. I think they are also a great idae to fly fpv.

When an FPV drone's motor halts abruptly, causing the drone to crash, it's often a sign of ESC Desynchronization. This guide explores the causes and provides strategies for correcting ESC desyncs through adjustments in BLHeli and Betaflight configurations no mater you are using sush as 1800KV brushless motor, small drone motor, 2806.5 Brushless Motor..

Understanding ESC Desync

Not every crash signifies an ESC desync. For example, a drone plummeting without spinning might indicate a failsafe or power loss. An ESC desync typically results in the drone spinning or flipping uncontrollably.

Analyzing Blackbox logs is the most effective method to diagnose an ESC desync, characterized by a motor stalling (ceasing to spin, thereby not generating lift), which in turn causes the drone to increase the motor's signal to its maximum 100%.

Without Blackbox, scrutinizing DVR footage closely can also hint at which motor suffered from the desync based on the direction of the drone's roll—the affected motor is usually the first to drop.

Causes of ESC Desync

ESC desync can arise from:

• Motor RPM exceeding the ESC's capability.
• Excessive electrical interference.

A high motor RPM can prevent the ESC from detecting the motor’s “zero crossing” point (commutation), and electrical interference can compound this issue. If the ESC fails to detect the “zero crossing,” it won't know when to activate the next pulse, causing the motor to stall eventually.

Addressing ESC Desync

Mitigating ESC Desync involves adjusting settings in BLHeli and Betaflight. Not all adjustments may be necessary simultaneously, but a combination thereof could resolve the problem.

First and foremost, ensure a low ESR capacitor is soldered to your ESC’s power input to minimize electrical noise, which is often a primary culprit.

BLHeli Adjustments:

• Rampup Power (or Startup Power): Opt for a lower setting, such as 0.125 in BLHeli_S or 12% in BLHeli_32. Increase the rampup power incrementally if the motors stutter upon arming, until the motors initiate smoothly without inducing desync.
• Demag Compensation: Increase to high to enhance the drone's ability to recover from desync episodes, though it might slightly impact performance.

Adjust these settings only if you encounter desync issues.

Betaflight Adjustments:

• DShot ESC Protocol: Switch to DShot if not already in use.
• Motor Idle Throttle Value: The standard setting is 5.5, which may be too low for smaller quads. Consider adjusting to a higher value, such as 6.5 or 7.

Conclusion

By following these strategies, your ESC Desync issues should be resolved, paving the way for fine-tuning your quad with these 10 easy steps
