Whiteboard eraser robot

http://people.ece.cornell.edu/....land/courses/ece4760
For our ECE 4760 final project we created a board climbing robot capable of cleaning the board autonomously. The robot uses neodymium magnets to stick to the board and moves across it with two continuous servo motors. The robot has bumper sensors on all four sides and keeps track of its orientation with two 1-axis accelerometers. The bot sweeps the board row by row starting from the top left corner. The bot can start at any point on the board and reposition itself to the starting point.
