motion sensors for robot

im working on an autonomous robot with four wheels and eight possible directions (forward, right forward, right,...). and i need to sense the motion of the robot to provide a feedback signal to the microcontroller.
gps system is not an option for me since i need to sense distances in the range of 10 cm. HELP??!1
