This is a demo of our CockRoach3000. The hardware was provided (already built) by the department, but we coded the behavior of the roach in C for the MC9S12C32 microcontroller.

The device has four bump sensors (front left and right, back left and right), which are magnets that move over an IC, inducing a current when sensor is bumped. It also has a photoresistor to detect the level of ambient light. These sensors are run through ADCs and into pins on the S12 for programmability.
