Roam Robotics has introduced Elevate, a new robotic exoskeleton that allows skiers with bad knees to conquer the slopes without knee pain. The exoskeleton is made of plastic and high-strength fabrics. The pneumatically powered unit attaches to the thigh and the ski boot. An air compressor, battery, and main computational circuitry ride in a 10-pound backpack. Attached to one of the shoulder straps is the controller. The device is designed to sense what the wearer is trying to do on the slopes and then provides the assistance necessary. It can offload approximately 30% of the user’s body weight, which reduces quadricep and knee load.
