ArduRoller Chassis

thingiverse

The laser cutting blueprint for the chassis of my ArduRoller balance robot is detailed below, featuring a 2.7mm bamboo ply (Ponoko) construction and various M2.5 screws sourced from Amazon. Instamorph low-melt thermoplastic will be used to fill any gaps. The brain of this bot is an Arduino Uno, while a Sparkfun Ardumoto motor driver handles the motor duties. Two 24:1 gearmotors from Sparkfun power the robot, and it rolls on a set of repaired 70mm Sparkfun wheels, fixed with Instamorph after they cracked around the axle. The bot's balance is maintained by an ADXRS613 gyro (Sparkfun breakout) and an ADXL203CE accelerometer (Sparkfun breakout), both mounted at their respective axis of rotation. Powering this bot are two 3.7V Li-poly 850MAh batteries from Sparkfun.
