This platform overview video shows quadrotors in flight, fixed wing hardware in the loop simulation and a novel experimental aircraft. It also introduces all PX4 hardware modules (available from 3D Robotics).
Update: For some reason the video is now marked private 🙁
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
