The long-jumping robot Grillo

This video shows some of the very first jumping prototypes plus n animation of the simulations made on the desired gait. The robot pictured here is a quadruped, 50 mm robot that weighs about 15 g. Inspired by frog locomotion, a tiny motor loads the springs connected to the hind limbs. Equipped with a 0.2 W DC motor, the robot is configured to achieve a forward speed of 1.5 m/s.
