My-HERO, the myoelectric untethered robotic glove. (Top Left) My-HERO provides five-finger extension and grip assistance and supports the wrist. (Top Right) My-HERO consists of an open-palm glove and foldable wrist brace secured in place with two Velcro straps. (Bottom) The two linear actuators mounted to the wrist brace attach to adjustable cable tie tendons for finger extension assistance and wire tendons sewn into the glove for grip assistance (highlighted in yellow in the top right figure). Mounted to the wrist brace is a 9 V battery and a Bluetooth microcontroller that communicates with an eight-channel electromyography armband that is used to detect the user’s intent.
