Centaur-style wearable robot cuts walking fatigue by 35%

Chinese researchers developed a centaur-style wearable that adds two legs behind the user via an elastic back interface, sharing load and lowering metabolic energy use by about 35% (with ~52% less foot pressure) when carrying ~20 kg, allowing longer, natural walking; designed to coordinate with movement and balance, it could aid heavy tasks in logistics, disaster response, and industry, and was described in The International Journal of Robotics Research.
