RT Series
The RT Series robot will be a 5' tall robot.  It uses two geartrains from a Power Wheels ride on toy, and two Parallax HB-25 motor controllers for motor control.   An Arduino currently serves as an interface between the Acer One netbook (the same one on Geoffrey), and the motor control.
Eventually the RT-01 robot will be jam packed with processing power and sensors.  Currently slated is.
For processing power.
These processing systems will be connected together to provide modularity.
The system will be open source, and both the hardware and software process will be documented for replication.
More pics and video to come, but here are a few.
