This project aimed to develop an active assistive knee device to aid the user in their gait cycle and stair ascent and descent. Currently, few devices exist on the market that offer a solution for those desiring a small amount of assistive torque in a low profile, cost-effective design. Experimental and literary research were performed to determine the amount of assistance needed from the device, and the ideal structure. A novel hinge design was created and, once partnered with the electromyograph and motor, provides 10% of the required torque at the knee for the user. Due to COVID-19, the team was unable to fabricate and assemble a working prototype. Improvements include refining the design to be smaller and lighter, and adding a second motor for increased torque.
