The purpose of this research is to develop a motorized wheelchair, to meet the special requirements of indoor use. A wheelchair prototype is developed, which uses two motors, controlled by a PWM controller. The PWM controller is based on a L298N Dual H-Bridge Motor Controller module with an Arduino board. The prototype has the ability to perform forward/backward motion and steering. These functions are controlled by a joystick mechanism, operated by disabled human. As a drive train from motors to wheels are used chain transmissions. Drive trains convert high motor speed to lower speeds but with increased torque. The proposed design solution allows wheelchair folding for transportation. Experimental tests carried out gives us a kinematic and dynamic characterization of the wheelchair.
