Micromice are small autonomous robots design to traverse a maze. The maze consists
of 256 squares (16 x 16) on a 18cm grid with recofigurable walls which are 1.2cm
thick and 5cm high. The floor of the maze is matt black and the walls are white
with red tops. There are three basic types of mice: Contact wall followers that
find there way around the maze by mechanically detecting the left hand wall. Non
contact wall followers that find there way around the maze by detecting the left
hand wall without touching it usually using optical sensors. Maze solvers that build
up a map of the maze as they search for the centre then calculate the best path
and return to the start and do as quick a run to the center as possible.
