ArduRoller

ArduRoller out for a spin

Second iteration of my ArduRoller balance bot with an all new wooden chassis.

Specs:
  • Chassis: laser cut 2.7mm bamboo ply (Ponoko); various M2.5 machine screws from Amazon; Instamorph low-melt-point thermoplastic to fill in the gaps.
  • Brains: 1 x Arduino Uno
  • Motor driver: 1 x Sparkfun Ardumoto
  • Motors: Sparkfun 2 x 24:1 gearmotor
  • Wheels: 1 set Sparkfun 70mm -- repaired with Instamorph after they cracked around the axle
  • Gyro: 1 x ADXRS613 (Sparkfun breakout) mounted at the axis of rotation
  • Accelerometer: 1 x ADXL203CE (Sparkfun breakout) mounted at the axis of rotation
  • Batteries: 2 x 3.7V Li-poly 850MAh (Sparkfun)

I've shared the code and assets at github.com/fasaxc/ArduRoller.
