LITEC Wiimote
From EWiki
Laboratory Introduction to Embedded Control (LITEC) is a required course for all engineering majors at RPI. Over the course of a semester, we use an 8051-based evaluation board to go from blinking LEDs to controlling an autonomous 20' blimp. There are plenty of opportunities to expand on projects, and here is what I want to do.
The most-used platform in LITEC is the LITEC Smart Car. It has a powerful drive motor with a differential transmission and a servo for steering. Normally this is controlled autonomously, but I want to build software and hardware to allow a Wiimote to control the car wirelessly. This will involve translating from the Bluetooth protocol the 'mote uses (using Darwiin) to serial commands sent wirelessly over some kind of low-cost wireless link to the serial port of the microcontroller.

First Step
wireless between laptop and Smart Car. Either wireless RS232 or wireless USB.
Second Step
accelerometer control of car's velocity. Lean the Wiimote left, right, forward, back to control car
Third Step
Mount IR LEDs on car so that the Wiimote's IR camera can see them. Point at the spot you want to see the car go to, and it will do its best to get there.
Equipment
Andrew Armenia suggests The Radiotronix RCT-433-AS and RCR-433-RPR to make a unidrectional 2400 baud link. These should be ordered through the electronics club shortly.
