Customer Ana Paula Almeida wrote this Portuguese-language paper about the 3pi Robot (1MB doc) as part of a Master’s program in Computational Modeling and Industrial Technology. The paper describes the 3pi in general and specifically how to write optimized maze-solving code.
This art installation by Matthew Richard uses 10 OctoBrite DEFILIPPI modules, 80 RGB LEDs, 40 servos, 7 servo controllers, and an Arduino.
Alex Louden has released an open-source template for custom 3pi expansion boards for use with the Eagle PCB design software. The picture shows an example expansion with an mbed microcontroller, Xbee, and accelerometers.

This simple obstacle-avoiding robot by forum user TomatoWire is based on the Maestro and uses continuous-rotation servos and distance sensors. The robot is programmed using the Maestro’s internal scripting language, without the need for an additional microcontroller.

AIRbot is a robot that can be controlled by a cellphone and can send images back to the cellphone. It uses a yellow RP5 tracked chassis, a transparent clear RP5 expansion plate, and a qik 2s9v1 dual serial motor controller along with the AIRcable S.D.K. and the AIRcable OptiEyes. The source code (both AIRcable and Nokia) and circuit diagrams are freely available.

In this project, an HD camcorder sits on a pan/tilt mount controlled by a Micro Maestro 6-Channel USB Servo Controller. A Wiimote is used to track an IR light source. Here is a video taken from the mounted camcorder:
