AI Technical Summary

Technical Problem

Existing upper limb rehabilitation robots have large overall weight and inertia in their joint transmission structure and poor flexibility in their drive mechanism, resulting in insufficient interaction comfort and safety.

Method used

Employing rope traction technology, the device is remotely driven via a Bowden cable. The motor is located away from the human-machine interface, reducing joint weight and inertia. The design, which connects the rope to the motor, enables flexible joint movement through five active degrees of freedom and one passive degree of freedom.

Benefits of technology

It reduces the overall weight and inertia of the robot's moving joints, improves the comfort of interaction and the flexibility of the drive mechanism, and provides structural safety assurance.
