Researchers at Southern University of Science and Technology in Shenzhen have unveiled a wearable robotic system that adds a pair of independent mechanical legs and a torso framework to a human wearer, forming a four-legged hybrid to assist with carrying heavy loads across difficult terrain such as stairs, ramps, and uneven ground, according to the South China Morning Post.Led by Chenglong Fu, the team of scientists designed the device to combine human cognitive advantages in path planning and decision-making with robotic capabilities for load-bearing and endurance in environments too hazardous or complex for fully autonomous systems. An elastic coupling mechanism...
