- This video demonstrates hopping locomotion of a single-legged hoping at various stride frequencies. The leg stiffness is adapted according to the controlled stride frequency to reduce energy cost
- We also utilize the hopping leg to investigate how leg stiffness can improve locomotion efficiency in compliant ground (tracks).
The following videos are a few examples of the capabilities. of the UZH1 robot. We show the different possible gaits and a video on gait changes as well as maneuverability:
(1) Walk-run-transitions. Dynamic transition from running to walking and vice versa with the leg-mass extended spring-mass model M-SLIP. To prepare the transition to walking, speed is reduced first (yellow dot). Leg damping is increased to induce the gait change to walking (red dot). Finally, we switch back to the original combination of speed and leg damping, which consequently induces a gait change to running (green dot).

(2) Limb-damage caused change of pedality. Our M-SLIP model can keep on with dynamic legged locomotion even if a hind limb in a quadruped suffers a sudden damage. At the instant of power-off, the damaged leg is moved to a neutral position where it does not hinder locomotion. At the same time, we induce a three-legged gait similar to those observed in dogs by adjusting hip stiffness, leg stiffness and control primitve (leg swings forward directly after lift-off) of the remaining hind limb.

LocoKit videos can be found on University of Southern Denmark's Modular Robotics Research Lab's YouTube page. However, here is a direct link to a LocoKit robot doing prong:
Here is video showing the new LocoKit mechatronics in action. Notice there is no intelligent control, it is just a hardware demonstration.
