| A variety of sensors can be used to allow a small autonomous robot to determine its position, including optical encoders on the wheels and off-the-shelf mechanical computer mice. However, both of these options have the disadvantage of being subject to surface traction and can only detect motion in a single dimension. In 1999, Agilent Technologies introduced an optical computer mouse that does not contain any moving parts and can accurately measure motion in 2 dimensions on just about any smooth surface. Optical computer mice detect changes in cursor position by acquiring sequential microscopic images of the surface underneath, comparing them, and then mathematically determining the direction and magnitude of movement. The goal of this project is to determine if a robot can use these new optical computer mice to drive a predetermined pattern. |
