objectives: wheelchairs are the prime mobility aid of persons with spinal cord injuries. manual wheelchair propulsion puts a lot of demand on the cardiopulmonary as well as the skeletal system. the main purpose of the study was to compare the effects of both arm ergometry training and progressive resistance exercise training of upper limbs on resting heart rate and distance covered during wheel...

A power assist wheel chair robot by which a patient can climb over steps/curbs without any helper's assistance is proposed. A patient can maintain inverse pendulum control of the wheel chair after raising its front wheels. Next, a patient can move to the step maintaining the inverse pendulum control, and can climb over the step being assisted by DC motor force. A light weight wheel chair system...

An automated system is developed to control the rotation of the wheel chair based on touch screen and head movement by the physically challenged person. Independent movement can be done by them with the help of an accelerometer device which is fitted on person’s head and a touch screen is placed with the wheelchair which can be operated by the person [1]. Based on the touch and head movements, ...

The purpose of this review is to highlight the wide array of interfaces developed so far to control wheel chairs. A preliminary study on wheel chair interfaces is presented. This is followed by various types of powered wheel chair control methods such as hand, voice, communication methods and hybrid. Wheel chair control methods for persons with reduced strength are also explained. Apart from al...

In this research work, an attempt is made to completely automate a wheelchair for wheeling and walking. For this the design criteria of the wheel chair are analyzed and then compared for an optimization task. Thus a newer design of wheel chair is developed which can be stable even when it is lifted to certain height. Using this stability of the design, legs are made to walk and to climb the sta...

the paper presents the optimization results for several electrical machines dedicated for powered electric wheel-chairs. The optimization, using the Hook-Jeeves algorithm, was employed based on a design approach which takes into consideration the road conditions. Also, through numerical simulations (based on finite element method), the analytical approach was validated. The optimization approac...
