This paper presents the design process and driving performance test results of a power-assist module to which cycloidal reducer is applied in order convert manual wheelchair into an electric wheelchair. The types electrification modules currently used electrify wheelchairs include front-mounted, rear-mounted, powered wheels. These assist devices are either difficult carry transport independentl...

D espite its obvious benefits to the user, the wheelchair represents a changed and intensely disliked lifestyle . It identifies the user as disabled and is a constant reminder of the disability . Moreover, the wheelchair becomes part of that person's self-image . For the prescribing physician or clinician, it is a frustrating reminder of an . inability to cure the condition . An appropriate whe...

This position paper is based on the premise that those who ride seated in wheelchairs are entitled to equivalent occupant safety when they are traveling in motor vehicles. The document summarizes research and best practice for safety and selection of crashworthy wheelchairs with the requisite features required by the WC19 safety standard when it is necessary for individuals to use a wheelchair ...

Paraplegia is a disability caused by impairment in motor or sensory functions of the lower limbs. Most paraplegic subjects use mechanical wheelchairs for their movement, however, patients with reduced upper limb functionality may benefit from the use of motorised, electric wheelchairs. Depending on the patient, learning how to control these wheelchairs can be hard (if at all possible), timecons...

*Dimensions given here for seat width and depth relate to space available to the occupant and are not overall dimensions for the chair or its components . floor vary with the width approximately as shown in Table 1. Selection of the proper seat width is important to comfort and stability . A seat too narrow is not only uncomfortable, but access to the chair is made difficult. Furthermore, the c...

AI and computer-vision techniques to read sign language and improve mobility aids such as wheelchairs and walkers. With this in mind, AI is being increasingly implemented in various types of tools designed to help the disabled. Those tools include screen readers and computer-navigation aids for the visually impaired, voice-to-text converters for the deaf, neural interfaces that interpret brainw...

This is an exciting time to be involved with research and development related to improving the mobility and function of people with physical impairments (1) . The recent and impending technological advances promise to change their lives in potentially profound ways: the confluence of technology, biological sciences, and social change have created an environment for progress and growing acceptan...

This paper reports on a set of theoretical and experimental investigations into the use of force reflection to enhance the dynamic behavior of human piloted vehicles, especially joystickcontrolled vehicles such as fly-by-wire jets, bulldozers, and powered wheelchairs. Briefly, force reflection is used in the manual controls to cancel the effects of feedthrough dynamics. Feedthrough dynamics ref...
