The robot was created as a testing platform for the IsoPod, any maybe to compete in mini sumo competition one day. For now it has a GameBoy camera which it can detect a line and follow it. The robot is built out of plastic and uses the Lego tracks.
The source code included here is to read an image from the camera. The image is scaled down from 128x128 to 32x32 and is stored in the memory. Since the IsoPod memory word is 16bits then two 8bit pixels are stored in one memory location. GBASM file is a process to read a line from the camera in assembly.
