Video showing the astromech in action, first with two legs then with the retractable leg. Due to the extra length needed for the retractable leg, it has to be locked in place internally, giving it the stability it needs to maintain traction. I also had to rework the locking mechanism for the leg when retracted, due to the placement of the battery pack on the back. ~H
