For millennia, physically challenged people have had to find different means to live their daily lives. In the early times, most of the used methods were very inconvenient and needed constant aid of other people. With time, however, these methods have been improving constantly and with the dawn of the revolutionary wheelchair, the hardship of physically challenged people was reduced a great deal. Although it is uncertain, the first known wheelchair is said to be made in 1595 in Spain, and since then with the advancement in technology, the wheelchair has come a long way and today’s sophisticated wheelchairs make life for physically challenged people very convenient. However, these sophisticated wheelchairs are also very expensive and unaffordable by the financially unprivileged people of the third world countries. Hence, an idea was proposed to produce an electrical wheelchair with integrated torque sensor technology which would ensure longer battery life and cut down overall costs and therefore, would be more affordable and convenient for the unprivileged people globally. The wheelchair was successfully produced, however had certain limitations and inconveniences. This thesis paper is about the modification works done on the existing torque sensor based electrically assisted wheelchair with dedicated solar charger kit to enhance performance.
