This was the robot built @ UT for my advanced mechatronics project. It has four IR sensors, one SONAR, a magnetic compass, an accelerometer, two QTI's at the bottom for color recognition and 3 servo motors. The robot uses the propeller chip from Parallax and is wi-fi enabled by using the XBEE pro chip on it and a modem nearby. All the sensor data is transferred to a computer nearby in real time. Cool stuff !! Loved it....
