Modular upper-limb rehabilitation robot

Modular Upper Limb Rehabilitation Robot

This technology is an upper limb rehabilitation device featuring a modular structure designed to support a patient's upper arm, forearm, and hand for rehabilitation exercises. Each module can be selectively attached or detached using a dovetail mechanism, and the kinematic structure allows for independent operation and control of the elbow, wrist, and fingers.

Conventional integrated upper limb rehabilitation robots require all components to be assembled regardless of the specific area needing rehabilitation, resulting in large installation footprints, high costs, difficulty in switching between left and right arm configurations, and low user convenience.

This technology utilizes a base frame and a modular design with a dovetail attachment system for the upper arm support, forearm exercise unit, and hand rehabilitation unit. This allows for selective assembly based on the specific rehabilitation area, easy switching between left and right arm use, and adjustable length mechanisms. Applicable to rehabilitation training, gait assistance, and medical/welfare services, it improves installation efficiency and utility by allowing hardware to be selected based on the specific body part requiring rehabilitation.

Key Features:

• A hand rehabilitation unit that is detachably installed at one end of the forearm exercise unit, supporting the human hand to facilitate wrist flexion/extension and finger flexion/extension exercises.
• An upper arm support unit that is detachably installed on the base frame to support the human upper arm.
• A forearm exercise unit that is detachably installed at the shaft end of the forearm rotation reducer.
• A forearm drive motor coupled to the base frame and connected to the forearm rotation reducer, which transmits rotational force to rotate the forearm exercise unit.
