To prolong the lifespan of your drone, regular maintenance ensures that the device performs at its best in future operations with fewer malfunctions and improved efficiency. Here are some maintenance methods divided into two situations：

1. Cleaning After Operation

The equipment needs to be cleaned after using corrosive liquids such as pesticides. You can follow the cleaning steps:

①Fill the tank with soapy water or the laundry powder. Start spraying to clean pesticide residues in the spraying system.

②Fill the tank with clean water and start spraying to wash off residual soapy water or the laundry powder in the spraying system. Place the empty tank in the aircraft and start spraying until all pipes are drained, avoiding damage to other devices during transportation or storage.

③Wipe the surface of the aircraft to remove potion stains and mud. Empty the tank and drain the pipes if the aircraft needs to be transferred or will not be used for an extended period.

2. Regular Maintenance

The regular maintenance should check and repair body structure, power system, spraying system, and power system timely.

①Drone frame: Check if any screw on the frame is loosening or missing, the components including landing gears, fuselage, arms, motors and antennas are in good condition, the connectors of each component are firmly in position, whether they have oxidized, and if the battery plug is deformed, check if the frame and components are breakages and cracks.

②Propulsion System: Check if the propellers, motors and ESCs are cracked or deformed, if any fixing screw is loosening or missing.

③Spray System: Check the wear of pump and tank, and check if the pump connectors have come loose or oxidized, etc.

④Power System: Before and after the use of the power device, you should check and clean each component including the battery plug and socket, ensuring that the power socket remains clean, dry and free of foreign objects.

Here I will introduce how to upgrade the EPS200's turntable.

As the new turntable is embedded with metal sowing blades, thickened and reinforced, which is more wear-resistant and not easy to deform, prolonging the service life.

Step1: Loosen the bottom knob, and take out the old turntable.

Step 2:Place the new turntable and align it with the screw hole positions, tighten the knob, then the turntable is upgraded successfully.

EPS200Pro also deeply optimized steering gear, control module and cables, making the spreader more stable and better performance. The modular design makes all parts can be replaced separately and conveniently. Follow EFT to get the latest product trends and preferential information.

My Holybro 500 v2 is equipped with a Luxonis OAK-D-Lite camera (depthAI) and a RPi4. A python artificial intelligence (AI) code on the RPi4 detects objects (f.i. persons) using mobilenet ssd. The area of the enclosing object rectangle estimates the distance of the object, while the center determines the yaw of the drone. 2 PID controllers determine the forward speed and yaw of the drone. Once the track switch is on, the drone is controlled in guided mode by the custom python code. This algorithm yields a satisfactory tracking behavior as shown in the video.

The stirring function of spreader can make blocky or sticky particles more uniform, and spreading operation smoother. Take EFT's spreader as an example to introduce how to quickly upgrade EPS200's stir bar to stir plate.

Step: Disassemble the spreader from the tank, remove the top screw, take out the stir bar, install the new stirring plate, then tighten the screw, the stirring bar is upgraded successfully.

As you can see, the umbrella-shaped metal stirring plate increased the force area and stir with greater power, which makes sowing smooth and non-blocking.

In the rapidly evolving landscape of drone operations, one of the most significant challenges is navigating beyond the line of sight (BVLOS). Operating BVLOS opens up endless possibilities for industries, but it also brings a host of crucial considerations to the forefront. Flight safety and risk mitigation take utmost importance among these considerations, as the safety of people, property, and the uncrewed aircraft itself is paramount.

Currently, most BVLOS operations require the presence of a vigilant visual observer (VO) who diligently scans the skies for potential obstacles and hazards. If they come across one, they must immediately notify the remote pilot in command to abort the drone's current mission. Therefore, it goes without saying how dangerous any form of communication lapse can be.

The Role of Visual Observers in BVLOS Flights

Before delving into the specifics of the various types and Detect and Avoid (DAA) technologies available, we must first understand the role of visual observers and why they are required. For example, the Federal Aviation Administration (FAA) in the United States specifies the operational requirements that must be met before flying unmanned aircraft systems. There is a requirement for a visual observer to perform the following roles for all drone operations that do not have a Part 107.33 waiver.

However, this human-centric approach can be both resource-intensive and limited in terms of continuous monitoring. There could be objects in the area of the drone operation, such as a small non-cooperative paraglider with no engine noise. It may be difficult for a human to accurately identify that and notify the remote pilot-in-command (PIC).

The Solution: AI-powered Detect & Avoid Technology

Detect and avoid (DAA) system enables operators to sense and avoid other aircraft and obstacles autonomously. These systems use sensors, such as radar, acoustic, and visual, to detect and avoid obstacles in the airspace. With DAA technology, drones can operate safely beyond visual line of sight, expanding their range of capabilities and applications.

Types of DAA Systems

There are several types of DAA systems, including radar, acoustic, and optical systems. Each of these systems has its own set of pros and cons, and the choice of system depends on the specific requirements of the drone operation.

Casia G: Iris Automation’s Ground-Based Detect and Alert System

Based on optical vision, Casia G is a ground-based surveillance system from Iris Automation to continuously monitor airspace and ensure UAS operations are safe from intruder aircraft. The sensors employ Iris' patented AI and computer vision technology to provide a full optical, 360° field of view for detecting and alerting to any cooperative or non-cooperative aircraft within a 2 km radius of the sensor's location.

Integration with FlytBase for Safe Remote Drone Operations

By integrating with the Casia G system, the FlytBasedashboard provides real-time data on intrusive aircraft, including type, live telemetry, and location on the map. Remote drone operators can monitor the status and radius of the Casia G sensor and receive immediate alerts if unauthorized aircraft are detected within their operating area.

BVLOS Approvals with Detect and Avoid Systems

The FAA has introduced a smart approach by incorporating "shielding" into their waivers, acknowledging that flying within 50 feet of the ground or a structure is likely safer for other aircraft. To achieve true BVLOS flights, the FAA requires some form of detect and avoid system, whether cooperative or non-cooperative, integrated into the operations.

The Way Ahead

While human visual observers remain important, technological solutions offer scalability and significant advantages. These solutions should be seen as tactical mitigation measures complementing other safety protocols. Cameras, sensors, and advanced safety technologies provide higher accuracy, continuous monitoring, and real-time responses, enhancing the safety of drone operations and opening doors to more advanced applications in the future.

Continued innovation and advancement in DAA technology are going to be essential for handling complex situations effectively and mitigating risks and safely integrating drones into the world’s third dimension.

Conclusion

The future of drone navigation is here, and it's called Detect and Avoid (DAA) systems. These systems, powered by AI and advanced sensor technology, are revolutionizing the way drones operate, especially in BVLOS operations. As we continue to innovate and advance in this field, we can expect to see safer, more efficient, and more scalable drone operations in the near future.

1. What parts are needed to assemble an agriculture drone?

To install a final agricultural drone, the following parts are required: drone frame, spreading system, spraying system, motor set, control system, and power system. All of these parts can be purchased separately. Here are some recommended suppliers, such as EFT's drone frame, SIYI's remote controller, JIYI's flight control, TATTU's battery. It is recommended to buy drone parts from Brand and reliable manufacturers,  which can ensure the stability of the whole drone and reduce the after-sales cost. The following are all the parts needed for a drone for your reference.

2. What You Need to Know When Select Drone Parts?

①Frame selection. The priority consideration goes to whether to choose a four-axis or six-axis drone frame. Six-axis frame is more stable for large load, while four-axis frame with small size is convenient to transport and suitable for outdoor operation, it is easy for newbie to get started. Drone frames from big-brand manufacturers are highly recommended, which could be more stable and durable.

②Motor set selection. The outer diameter of the frame arm needs to be taken into account when purchasing, the wrong size will cause mismatch. The load also needs to be considered, the heavier the load, the larger the motor required. You can select an integrated motor set directly, or buy motor, Base, and paddles separately because welding them by yourself can be cheaper. If you buy the spare parts separately, please note that the paddles and motors must match the correct CW and CCW code, and each drone must have the same number of CW and CCW.

③Flight control selection. Standard flight control for agriculture drones such as K++ . The open-source flight control requires strong software development skills which is not recommended to beginners.

④Battery selection. There are smart batteries and pouch batteries for drones. The battery must be selected according to the frame to avoid overloading or insufficient power supply. The most common battery on the market is TATTU. The battery interface model and communication protocol also should be cared

Below is a chart of some frames with recommended motor and battery for reference.

What is Remote ID and how to stay compliant?
Remote ID is a system that allows drones to transmit identification and location information. This information can be received by other airspace participants, including authorities, pilots and the general public.

Who has to use Direct / Broadcast Remote ID?

Under new regulations in the US and EU, most drones weighing more than 249 grams (0.55 pounds) must be equipped with a Direct / Broadcast Remote ID system by a certain date. This responsibility applies both to recreational drones and commercially flown drones.

Previously, I introduced how to spray with Manual Operation Mode and A-B Route Operation Mode. Today, I highly recommend you use the more intelligent operation mode —— fully auto operation mode. It can plan route and avoid obstacles accurately. However, you should set blocks, measure and plan it in advance, which requires more preparation. Taking the Z series holistic system as an example.

Step 1.Click Agri Assistant >Connect> H12/MK15 >Ground Plan > New Plot.

Step 2.Select the planning method①Handheld GPS(RTK point device) ②Flight GPS ③Map Selection ④Waypoint planning. Method① and ② are widely used.

Step 3.Set Ground Name, move the handheld point device or fly the aircraft to the field, click the Boundary Point on the right side of screen to add dots in turn.

Step 4.About obstacles, move handheld point device or fly the aircraft to the obstacles, click Obstacle Point. There are two methods to mark it, Polygon barrier point and Circle obstacle area. Note that if you select Polygon barrier point, use the Boundary Point to dot. Handheld RTK point are recommended.

Step 5.Click “Save” after all operations are done, tap on the left, select the newly saved plot, click Share > Confirm, the plot information is listed in Block Data.

Step 6.Tap, select the plot, adjust the route and click “Start”, then check the parameters according to prompt. Click Confirm and Slide Right Start to take off.

You can select the desired mode for spray according to the application scenarios. What kind of work mode have you used? Welcom to share your opinion.

Last time I introduced how to use manual operation mode for spraying. Today, I will continue to take the Z series holistic system as an example to share another work mode—A-B Route Operation Mode, which can form a straight route line between two points.

There are two methods can enter the AB operation mode:

Method 1:

1.Click Agri Assistant >Connect> H12/MK15 >Start

2.Complete the preflight inspection and unlock for takeoff in Attitude Mode.

3.After takeoff, fly to the field where you want to work. After the aircraft stabilizes, click “A” to enter the AB operation mode. Click the A near your side to add point A. Detailed flight parameters will appear on the screen. Set the parameters, then push the stick forward, fly the aircraft to the other side of the field and click “B” to add point B.

4.After adding point AB, click “Start”, then choose “To the left” or “To the right” then the aircraft can automatically identify the planned route.

Method 2：

1.Fly to the field where you want to work. After the aircraft stabilizes, move the left lever on the side close to you. Switch Attitude to Auto mode, and then fly to the A position to add point A , the detailed flight parameters will appear on the screen. After setting the parameters, push the lever forward, fly the aircraft to the other side to add point B.

2.After adding point A and B, fully push the right stick to the left or right, and the aircraft can automatically identify the planned route.

In the next article, I will introduce you the last spraying operation mode. If you have any question, welcome to share your opinion.

*The above steps are for reference only.  Please refer to product use manual when using.

There are three operation modes for agriculture drones during spraying. Manual Operation Mode, A-B Route Operation Mode, and Auto Operation Mode. Today, I will take the Z series holistic system solution as an example to share how to operate the manual operation mode with you.

Step 1. Open Agri Assistant App on remote controller, click Connect> H12/MK15 >Start.

Step 2. Tap “Spray” in the top information bar, set Spray Type to “Spray Auto” , set the Hec Dosage and Disc speed, then switch Spray type to “Spray Manual”, tap screen to confirm. Take off the aircraft in the Attitude Mode, fly to the field, switch to the Manual Operation Mode, then operate the aircraft by sticks, press C and D to spray.

The manual operation mode can apply to various complex fields, but it requires skilled flyer to operate. In the next article, I will introduce a simpler spraying work mode to you guys. If you have any question, welcome to share your opinion.
