The idea of this demo is to design and program a robot that can solve a simple maze.
The final design of the Crabot uses three bump switches. These bump switches are designed using wire wrapped around one of three bumpers connected to the 5V out put of the OpenCM micro-controller. When contact is made to a pad made of aluminum foil , one of three digital I/O pins is pulled to High trigging an interrupt in the program and causing the robot to adjust it’s course. Below are the final designs, photos and a video of a test run for the Crabot wall following robot.
