Development of wrist bending rehabilitation robot

This paper describes the wrist bending rehabilitation robot using a four-axis force/moment sensor. The robot can be used to exercise the wrist bending rehabilitation for severe stroke patients lying in bed wards or at home. The manufactured four-axis force/moment sensor which can detect two directional force Fx, Fy and two directional moment Mx, My, was attached to the developed rehabilitation robot and allows the rehabilitation robot to measure a bending force (Fx) exerted on a wrist, the signal force Fy and moments Mx, My which in turn allows the device to be used safely. The results of a characteristics test for the developed rehabilitation robot showed that it was safely operated while the wrist bending flexibility rehabilitation exercise was performed. Therefore, it is thought that the developed rehabilitation robot can be safely used with severe stroke patients.
