The robot was designed to jump without inflicting serious damage
to its body and to recover its initial pose after the jump. Thus, it
must be flexible and contain a self-returning mechanism. This was
accomplished by installing suspensions on the wheels and a bar
along the back of the robot. During a jumping maneuver, the bar
is released from the robot’s back, and when the robot hits the
ground, the bar is deflected by a spring and returns to its original
position.
