Provided is an upper limb exercise apparatus including: a table (T); a first link (L) and a second link (L) which are disposed above the table and are used for a left arm exercise and a right arm exercise, respectively; and handles () provided at ends of the first link and the second link so as to be gripped by the left hand and the right hand, respectively, and comprising: cameras () provided inside the handles () so as to capture images of fingers holding the handles; and a control determination unit configured to detect and determine an action of a user gripping the handles on the basis of the images captured by the cameras. It maximizes the opportunity to use the upper limbs by means of coordinated movement of the pair of arms, and improves the upper limb function of stroke patients with disabilities caused by a stroke.

Disclosed is a wearable robot for assisting a wrist, including: a plurality of flexible actuators; and a control unit configured to control any one of the plurality of flexible actuators to be contracted or relaxed according to a wrist movement of a wearer. Each of the plurality of flexible actuators includes: a driving part which is contractively deformed by a current or transfer heat applied from the control unit or is relaxed when the heat is lost, and a refrigerant circulating part which is implemented to surround the driving part and circulates a refrigerant so that the contractively deformed driving part is cooled under control of the control unit.

Wearable robot for assisting upper limb movement by using artificial muscle

An upper limb exercise apparatus comprises a base, a frame, and a display mounted on the frame. The apparatus further comprises 5-bar linkage-type movable parts positioned on the display and including a first link and a second link. The first link comprises a 1-1 member having one end attached to the frame and being rotationally driven, and a 1-2 member having one end rotatably attached to the other end of the 1-1 member, the other end having attached thereto a handle for gripping. The second link comprises a 2-1 member having one end attached to the frame and being rotationally driven, and a 2-2 member having one end rotatably attached to the other end of the 2-1 member, the other end having attached thereto the handle and the other end of the 1-2 member. Series elastic actuators attached to the 1-1 member and the 2-1 member provide torque.
