Wearable robotic apparatus for increasing muscle strength of upper limb

摘要

According to an embodiment of the present invention, a wearable robotic apparatus to increase muscle strength of an upper limb comprises: an upper arm unit having an upper arm body portion, a forearm actuator portion fixated to the upper arm body unit, and a forearm link portion connected to the forearm actuator portion; and a forearm unit rotationally connected to the forearm link portion. The forearm link portion comprises: a forearm driving link connected to the forearm actuator portion; a forearm hub link connected to the forearm unit; and a forearm coupler link connecting the forearm driving link and the forearm hub link. As such, muscle strength of an upper limb of a user is able to be improved.
