Hello guys,

The YANGDA VTOL drone is demonstrating a feature like this in the video: the flight platform like a boat or a car will move after the VTOL takes off to carry out a mission. When the mission is over, the VTOL can fly back to the platform and land there, even though the platform is already far away from the original drone take-off position. The whole process will be totally in autonomy.

Lithium Ion battery Pack designer utility

8922509889?profile=RESIZE_710x

Lithium ion batteries have a higher energy capacity than Lithium Polymer packs, in general. Higher capacity lithium ion packs can be designed if the current draw of the drones are known. We have built a web utility to find the right chemistry of cells to use, from among the hundreds of different cells. 

Input the max weight, and current discharge of the drone and see: 

  • Battery cell configuration (number of cells in parallel and series) 
  • Approximate flight time as compared to current aircraft (without weight change)
  • Battery weight.

Reach out to us shout@rotoye.com to get free access to this utility.

3D printed truck

The high cost of good RC truck kits, diminishing need for such kits & the noise of gearboxes made me look elsewhere for a robot platform.  3D printing a truck from scratch, with only a few metal parts still being off the shelf, was the next step.  The only parts which have to be outsourced are the motors, steering servo, & steering knuckles.  Everything else is 3D printed or home made electronicals.  The size was based on the original Tamiya lunchbox.

The remote control is a single paw 3 channel, with 100mW radio, ball point pen springs, hall effect sensors.

The remote control is charged inductively.

Motors are direct drive Propdrive 4248's of any KV rewound with 20 turns of 26AWG.   They don't produce enough torque to go up hills.  The motor sensor is a dual hall effect sensor resolver.  

The main problem is cooling the motors while getting more torque.  Metal motor mounts of the right shape continue to be cost prohibitive & PLA doesn't dissipate heat.

Great post from NASA explaining how the Mars helicopter autopilot works:

----

Before each of Ingenuity’s test flights, we upload instructions that describe precisely what the flight should look like. But when it comes time to fly, the helicopter is on its own and relies on a set of flight control algorithms that we developed here on Earth before Ingenuity was even launched to Mars.

To develop those algorithms, we performed detailed modeling and computer simulation in order to understand how a helicopter would behave in a Martian environment.  We followed that up with testing in a massive 25-meter-tall, 7.5-meter-diameter vacuum chamber here at JPL where we replicate the Martian atmosphere. But in all of that work, we could only approximate certain aspects of the environment. Now that Ingenuity is actually flying at Mars, we can begin to assess how things stack up against expectations. Here are some key aspects of the flight control system’s performance on Mars.

Dear Friends,
1 months ago our cubesat satellite "FEES" release in space by Soyouz 2 . The hardware is based of VRBrain 5 architecture , we put in space a STM32F4 micro controller . The first release don't use Ardupilot , hope the next one with your help and our experience could be . After a lot of test and study about the communication in space we found that lora protocol it's a great option for sat to ground and could be ground to space communication . So actually FEES is still in space and continue to trasmit it's position to earth. Now for recived it we are using global opensource network called TinyGS . Now we start we next step that's is try to constantly comunicate with the sat all around the world . So now we need the help of our great community . We need put small ground station around the world for connect our cubesat at any time of day and night. Fees is only first sat that we have in space but my opinion is that in the future we can add more cubesat and interconnect it and

From Applied Aeronautics:

Albatross UAV made its first appearance in 2013 on DIY Drones. The Albatross UAV Project, as it was titled, set out to design a composite UAV that met a long list of precise and ambitious performance metrics. Those were: > 6KG MTOW, plenty of room for sensors and batteries, up to 4 hours of flight time, wide flight envelope, and last but not least, efficiency. Over the span of 13 months, the Albatross began to take shape through meticulous design and testing. To date, our company has Albatross systems flying in over 50 countries and on every continent. Still, it’s important to us to always remember our roots as a company spurred by the passion to create something truly incredible from the ground up.

Hacking a cheap drone to run PX4

8831264061?profile=RESIZE_710x

From Hackaday:

Sometimes bad software is all that is holding good hardware back. [Michael Melchior] wanted to scavenge some motors and propellers for another project, so he bought an inexpensive quadcopter intending to use it for parts. [Michael] was so surprised at the quality of the hardware contained in his $100 drone that he decided to reverse engineer his quadcopter and give the autopilot firmware a serious upgrade.

Upon stripping the drone down, [Michael] found that it came with a flight management unit based on the STM32F405RG, an Inertial Measurement Unit, magnetic compass, barometric pressure sensor, GPS, WiFi radio, camera with tilt, optical flow sensor, and ultrasonic distance sensor, plus batteries and charger! The flight management unit also had unpopulated headers for SWD, and—although the manufacturer’s firmware was protected from reading—write protection hadn’t been enabled, so [Michael] was free to flash his own firmware.

We highly recommend you take a look at [Michae

Drone swarms for fire-fighting

From Robohub:

For my PhD, I’m studying how global problems such as wildfires and aid delivery in remote areas can benefit from innovative technologies such as UAV (unmanned aerial vehicle) swarms.

Every year, vast areas of forests are destroyed due to wildfires. Wildfires occur more frequently as climate change induces extreme weather conditions. As a result, wildfires are often larger and more intense. Over the past 5 years, countries around the globe witnessed unprecedented effects of wildfires. Greece has seen the deadliest wildfire incident in its modern history, Australia witnessed 18,636,079 hectares being burnt and British Columbia faced wildfire incidents that burnt 1,351,314 hectares.

Rather than jump straight in to the design of swarm algorithms for UAVs in these scenarios, I spent a year speaking with firefighters around the world to ask about their current operations and how UAVs could help. This technique is called mutual shaping where end users cooperate with developers
