| Summary: | Rehabilitation training is a method of post-treatment for physically injured part of body especially the stroke patients. The training task such as massage and repetition exercises are needed to help them to have a normal life as before by a physiotherapist. The physiotherapist or physical therapy is a person who has experienced to treat disease or injury by physical methods. Therefore, a main objective of this paper is to develop a nursing-care robot system that can assist the stroke patient in doing daily activities. A one-degree of freedom nursing robot was designed based on the right-hand bicep using CATIA software. This robot was associated with the electromyography (EMG) sensors in order to collect the data from the muscle contractions. Meanwhile the EMG sensor is a muscle sensor that detect an electrical potential between the two-contraction flexion or extension muscle using the polymer Ag/AgCl coated electrodes. Then, the data from the muscle was sent to the Arduino microcontroller to control the servo motor. The different angle of servo motor can give the direction of movement of the nursing-care robot. The nursing robot was activated by electrical potential from the contraction of the muscle. The value of servo angle from 0 to 100 degrees angle made the robot will move up and down. The movement of robot in up and down direction is likely same as the therapist assistance doing to their patient. The size of robot is about 600 mm 100 mm length and width and then was fabricated using 3D printer with one degree of freedom (DOF). The limitation of this project is focusing only the hand right hand bicep brachii muscle physiotherapy exercise. © Published under licence by IOP Publishing Ltd.
