- Actuators / output devices: Toshiba 6612FNG 1A motor driver., Tamiya twin-motor gearbox kit at 203:1
- CPU: arduino uno
- Power source: 2 AA cells for motor, 1 9V for Arduino electronics.
- Programming language: Arduino
- Sensors / input devices: HC-SR04 ultrasonic sensor
- Target environment: indoor flat surfaces
This is my first robot. Arduino Uno based, although I will end up trying out a TI Launchpad brain as well.
Total - $38 - not including Uno and proto-shield.
Tamiya twin-motor gearbox, truck wheels/tires,round robot platform, ball caster - $25
Pololu TB6612 FNG motor driver and carrier - $9
Battery holders - $4
Cheap Pololu round robot chassis, Tamiya twin-motor gearboxes, Tamiya truck tires. 9V battery pack for the Arduino. 2 AA battery pack for the motors, although I need a little more juice. I may add another 2 AA battery pack and supply each motor separately, or use a 3 battery pack and see how the motors like 4.5V.
Ongoing project. Just about to shoot my first video of the robot in basic maneuvering. No sensors installed at this time.

Hehe - Redbull gets the job
Hehe - Redbull gets the job done! Very nice robot by the way and very affordable.

Re: more batteries for your motors
You could always add a second pair of batteries in parallel rather than adding a 3rd battery in series.
