Our R&D department has struck again with another example project, and yet again we’ve gone and put together a bundle for it.

This project allows the Brutusbot to negotiate its present environment using a panning micro servo with an infrared distance sensor (GP2Y0A21) on it. After assembly, the CMDR Shield is placed onto the Freeduino (or Arduino) to allow it to control the Tamiya twin motor gearbox. We’ve even put together some sample code and a circuit design diagram (both under documentation below).

We have designed this bundle to use a split supply to cut down on any noise from the motors affecting the sensor data, so you’ll need 9V battery to power the Freeduino and the 6-cell ‘AA’ battery pack with be hooked up to the motor shield.

By using the Freeduino plus Adafruit Motor shield this bundle becomes a 2-hit combo of open-source electronics so not only does your tank travel in style but it is part of the world-wide OSHW movement.

You can find a circuit overview under the Resources Tab.
