Abstract
The article describes an automatic adjustment of the knee joint mechanism and the elastic ankle joint mechanism for providing physical gait assistance when walking for the elderly. The self-aligning knee joint can help the knee flexion/extension movement and compensate for the transitional movement of the knee in the sagittal plane. The elastic ankle joint mechanism has a built-in spring and pressure sensor to reduce the additional pressure on the ankle joint and detect it in time. The knee joint walking process is simulated in ADAMS and its performance is verified based on the trajectory. The prototype materials are carbon fiber and aviation aluminum, which reduces the weight of the device. The experimenter wears a prototype to simulate various real motion postures, and performs pressure detection on the sitting process to make the calibration result more realistic and reliable.
