Video of the week: World’s most efficient walking robot /v ideo della settimana:Il robot a piedi più efficiente del mondo Segnalato dal Dott. Giuseppe Cotellessa / Reported by Dr. Giuseppe Cotellessa This week’s Thursday video comes from Georgia Tech, where researchers have created what they say is the world’s most efficient walking humanoid. DURUS, kitted out with size 13 trainers, is designed to mimic the human gait as closely as possible, pushing off its toe, landing on the heel of its foot, and rolling through its step. Springs between its ankles and feet act in a similar way to tendons, allowing for a stride that stores mechanical energy from a heel strike that’s reclaimed as the foot lifts off the ground. According to the team at Georgia Tech’s AMBER-Lab, the natural gait makes DURUS extremely efficient. Locomotion efficiency is universally measured by a ‘cost of transport,’ which is the amount of power used divided by...
