 The proposed HIP Exoskeleton, Su-Chao-Exo, is designed to provide variable torque velocity characteristics for elderly users. It features a two-motor variable speed transmission which allows for adjustment of torque and velocity in real time. This enables the device to meet the needs of various activities such as standing up from a seated position, walking, running, and climbing stairs. The device is also lightweight at only 2.85 kilograms, making it more comfortable to wear than other similar devices. Bench testing and initial human subject testing have confirmed its effectiveness.
