Objective: To design a bedside upper limb rehabilitation training robot for patients with upper limb hemiplegia caused by stroke. Methods: By studying the structure and movement of human upper limbs, the configuration and size of bedside upper limb rehabilitation robot were optimized. Me-chanical design is carried out by integrating functional configuration dimensions and other factors through modular modeling idea, and the strength of key components is checked by ANSYS simula-tion. The kinematics model of bedside upper limb robot is constructed, and the forward and inverse kinematics equations are calculated and analyzed to study the robot training trajectory. Results: The bedside upper limb rehabilitation training robot had no mechanical interference in the verifi-cation process and could meet the requirements of upper limb rehabilitation training. Conclusion: The bedside upper limb rehabilitation training robot is reasonable in design and feasible in meth-od. The training effect has reached the expectation.
