Adafruit IndustriesMini Robot Rover Chassis Kit | 2939

This kit gives you everything you need to build the shell of a 2-wheel-drive Robot Rover! You get the chassis, 4-6 VDC motors and wheels. You'll fill in the rest with power supply, microcontroller or microcomputer and a dual H-bridge motor controller.  

To run the motors, you can use basically anything that can do two bi-directional brushed DC motors at ~5V and 1A. To steer the wheels, you'll need something to toggle the motor driver and a way to power the rover/microcontroller (we used a AA Battery Pack and a 3.7v 350mAh LiPoly Battery), but this is all up to you and your imagination!

Kit includes:

2x Wheels
2x DC Motors in MicroServo shape
1x Support Wheel
1x Metal Chasis
1x Top Metal Plate with mounting hardware

Assembled Dimensions:

Length of Metal Chassis: 156mm / 6.1"
Width of Car (wheels assembled): 103mm / 4"
Height (with top metal plate and wheels): 73.5mm / 2.9"
