Pololu m3pi Robot with mbed Socket

The m3pi robot is a fully-assembled, upgraded version of our popular 3pi robot. It consists of a 3pi robot base connected to an assembled m3pi expansion board that simplifies augmenting your robot’s capabilities with an mbed development board (or other microcontroller boards), wireless modules, and sensors.

Since the m3pi robot is an expansion of the 3pi robot, it also has all the features of the 3pi robot:
Max speed of around 100 cm/second
Regulated motor voltage (performance is unaffected by battery voltage)
5 reflectance sensors on underside of leading edge for line following and maze solving
8×2 character LCD for debugging, feedback, and user interfaces
Piezo buzzer for simple sounds and music

While the m3pi’s abilities can be enhanced through the addition of a number of hardware modules, the robot is fully operational as it ships and can be used just as a 3pi robot with an expansion board (in which case you will need an AVR programmer). Alternatively, you can leave the default serial slave program on the 3pi base and use an mbed (or your favorite microcontroller board) as the high-level m3pi controller by using it to send serial commands to the 3pi base. Wireless functionality can be added via the XBee or Wixel sockets, and you can use the expansion board’s prototyping space for sensors or custom circuits. The m3pi is powered by four AAA batteries (not included). We recommend rechargeable batteries
