Drone control

From Rsewiki

Drone project

This project is intended to be a rather simple core drone stabilizer application based on Teensy and the prop shield.

Intended to be expanded with an outer control loop with a non-realtime sensor, e.g. GNSS, camera or laser scanner.

Propeller - motor performance

Measured with the app below, using the motor 3508-700KV Turnigy Multistar 14 Pole Brushless and a 14x5.5 carbon propeller. The ESC is a Hobby-wing x-rotor 40A controller.

Time responce

With 11 V supply (3 lipo cells). From 1.1ms to the ESC (idle) to 1.9ms almost full throttle. The ESC update frequency is 400 Hz.

With 11 V supply (4 lipo cells). note that 30 amps is not sustainable, the motor gets hot fast.
