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

 

 

Please see the 3pi robot product page for a more comprehensive description the 3pi’s features and 3pi resources (user’s guide, projects, videos, etc).

Using the m3pi

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. For more information on additional components that you might want for your m3pi,
please see the Other Things You Might Need section of the m3pi user’s guide.
 

mbed

The key feature of the m3pi expansion board is that it enables the use of one
of ARM’s powerful 32-bit mbed development boards as the robot’s high-level controller,
offering significantly more processing power and free I/O lines than the 3pi’s built-in 8-bit AVR microcontroller.
The base 3pi robot ships preprogrammed to serve as a serial slave, so all you need to get started is an mbed controller
(sold separately or as part of a combination deal that includes an mbed NXP LPC1768 with the m3pi robot).
The mbed plugs directly into a socket on the expansion board (no soldering is required) and connects to all of the hardware on the m3pi expansion board as well as the serial lines of the 3pi base. Library support and sample programs for the m3pi are available

from mbed.org, making it easy to get your mbed-controlled m3pi robot up and running.

This project originated as a prototype created by ARM’s mbed team to help showcase the
mbed at various events and exhibitions. The picture below shows ARM’s orignal m3pi (left) next to our m3pi:

Note: Pololu’s m3pi robot does not have an integrated battery charger the way ARM’s prototype did.

Wireless

The expansion board also makes it easy to add wireless
capabilities to your m3pi robot by providing sockets for XBee or Wixel modules.
The expansion board connects these modules to one of the mbed’s serial ports,
and jumpers can be used to connect them directly to the serial lines of the 3pi base, so your robot
can communicate wirelessly even without an mbed as the high-level controller.
Because the Wixel is programmable, the Wixel can also be used as the m3pi’s
high-level controller when the serial jumpers are in place.
