This paper is concerned with the designing and making power lifting wheelchair. This wheelchair is studied based on the mechanical and electrical engineering concepts and theories. The statics and dynamics are studied with moving and lifting motion. The power lifting wheelchair is compared with the previous model, the power standing wheelchair, in the sense of kinematics and kinetics. The main functions of these two models are to reach to the standing height of normal person and to move by electrical power. However the lifting mechanism gives more comfortable feeling to users when the chair reaches to the high position with sitting in chair. Without stretching the user’s leg, the X-truss mechanism is applied in this wheelchair. Also the wheelchair is controlled by the joystick attached on the arm rest. The real size model is made and investigated by the test drive. Finally, this power lifting wheelchair proves the possibility of commercial production.
