A chair with wheels is called a wheelchair, designed to be a replacement for walking on foot for disables. The machine comes in deviations where it is forced by motors or by the seated dweller revolving the rear wheels by hand. Often there are handles behind the seat for someone else to push it forward. Wheelchairs are used by people for whom walking is difficult or unfeasible due to infirmity (physiological or physical), injury, or disability. People with both sitting and walking disabilities often need to use a wheel bench.
Electric wheelchairs make use of either gears or belts or occasionally both. Power wheelchairs with belts are classically very quiet, but they need extra maintenance. new gear drives are comparatively quiet and low-maintenance, but they tend to wear out more quickly then belt drives and get noisier in the process.
Researchers of the Florida A&M University/Florida State University Engineering college are trying to make the life of those people easier who are completely dependent upon electric wheelchair by using an urbanized technology of military robotic vehicles. Their prototype electric wheelchair can detect hazardous terrain and change driving strategies suitably is so promising that the US Army has offered to fund. If all goes well, we could be seeing these new-age chairs within five years — CES 2016 can’t come soon enough.
