The term 'Walker' is defined for this competition as any robot that uses a reciprocal linear mechanism for locomotion. If this mechanism is driven by a rotary motor, reversal of the direction of the mechanism (as required for up/down or forward/back motion) must require reversal of the motor. In addition, the actuator in contact with the floor must move backwards and forwards with respect to center of gravity of the robot.
The robot, once activated, has three minutes to traverse the obstacle course. The robot with the shortest time, measured when any part of the robot crosses the finish line, shall win. If no robot completes the course, the robot covering the most distance shall be deemed the winner.
