The German firm Festo developed the BionicKangaroo, a robotic kangaroo appropriately named. It features a “tendon” in its leg that drives it forward and captures energy on touchdown. It adjusts the tail for balancing during the time its legs move forward for landing. The impact drives the legs into position for a subsequent leap, and the spring-loaded limbs help for another hop right after landing.
