Wrote some code!
For the Teensy ; https://gist.github.com/buzztiaan/7a10806c974db5884cf62acdf7cc2849
For the Pi ; https://gist.github.com/buzztiaan/dc600e571a6332caae1f5952dfbd046b
This now works well, and i can drive around the hackerspace remotely :D

Vitamins


  • Teensy 2.0 board
  • MPU6050 breakout board (i2c)
  • HMC5883 breakout board (i2c)


  • 2x White 8000mcd LEDs (TODO)
  • (some amount) WS2812 or other leds (TODO)
  • remove unwanted leds (TODO)


  • 2x 18650 in parallel config
  • 2x DCDC boost converters , one 5V for pi & teensy , one 6.2v for motors


  • simple microUSB 1A charger board

Setup

Planned software setup ;



Something for sending 4 PWM signals to the DRV8833 (arduino pro mini? teensy? bit overkill .. )


Or connect the DRV8833 to Pi directly?


Beyond camera and 6dof no other sensors for now. Some kind of external brain ros instance aswell? LXC?
