A 9-Dof wheelchair mounted robotic arm system (WMRA) has been developed to assist wheelchair-bound persons with upper limb motion limitations to perform activities of daily living (ADL) tasks. In this paper, we utilize mobile manipulation control to keep the end-effector stationary while moving the base and vice versa. This allows easier execution of a group of pre-set ADL tasks including opening...
Wheelchair-bound persons with upper limb motion limitations can utilize a wheelchair-mounted robotic arm (WMRA) to perform activities of daily living (ADL) tasks. In this paper, an optimized control of our 9-DoF system, consisting of a 7-DoF robotic arm and a 2-DoF power wheelchair, is achieved. For effective ADL task execution, positioning the end-effector with proper wheelchair orientation was optimized...
A model of the human upper limb was developed for predicting the motion of the human upper limb while performing activities of daily living. This study focuses on the effect of a joint limit function on the ability of the model to perform human like movements. This measurement was analysed by comparing the modelled joint movements with recorded movements of subjects while drinking from a cup, opening...
