Stampe 5 is a three wheeled robot with differential steering, controlled by a Basic Stamp 2sx chip onboard the robot. When turning on the spot, the orientations of the rear wheels are changed, allowing the robot to turn around its centre point. With other angles of the rear wheels, the robot turns around points outside of the robot. This can be used to have the robot go around an object in front of it, while keeping facing the object.

A forward pointing Devantech SRF04 ultrasonic sonar module is sweeping from side to side measuring distances in a 90 degree arc, and a second, downward pointing sonar module detects thresholds and other unevenness in front of the front wheel. Stampe 5 uses a Devantech digital compass for navigation. The program has indoor and outdoor modes with different distance tolerances for the downwards-pointing sonar.
