Helium Balloon-Like Unit Keeps Two-Legged Robots Balanced

(InterestingEngineering) Robots struggle with balancing on two legs and often fall down. Even things as simple as children’s toys can only walk a few feet before tumbling forward. The Buoyancy Assisted Lightweight Legged Unit (BALLU) looks to change that. BALLU is filled with helium and looks like a balloon on skinny chicken legs. The helium keeps the body upright to avoid falls.
UCLA’s Dennis Hong with the school’s Robotics and Mechanisms Laboratory created BALLU and said, “We asked ourselves, ‘What if we could change the direction of gravity?’ and this led to the concept of BALLU.”
