In order to help hand dysfunction people to rehabilitate hand muscles and train hand muscles, we designed and developed a wearable rehabilitation equipment glove. First, we collected data from a sample hand and fitted its motion trajectory. Through analysis and comparison, we decided to use the linkage mechanism as the actuator and pneumatic drive as the driving method. In order to ensure flexibility, accuracy and stability, we designed and optimized the number and position of the connecting rods. Finally, we will get a set of rods that can simulate the movement of the fingers, and use springs to increase the flexibility of the mechanism. We studied the rigidity of the mechanism and determined the material of the device. After obtaining the model, we will perform a static analysis on the final state of the finger to ensure the safety of the device.
