THE DEVELOPMENT OF SMALL FREE 4-WHEEL DRIVE ELECTRIC CART FOR THE DISABLED

Abstract

The objectives purposes of this research ware 1) to develop small free 4-wheel drive electric carts for the disabled, 2) to measure the performance. Of the created model that facilitates the disabled to be able to support themselves when necessary or to help them with mobility. The researchers researched and built free electric carts for the disabled. The highlight is that it is possible to move freely on slopes, rugged roads, elevations, and uneven floors. The results from testing the boost control system showed that the 4-wheel drive electric cart could increase its speed from a constant speed of 10 km/h to 18.8 km/h; with the current voltage measured at 20 amps and the direct current voltage measured at 9.8 amps when they were first launched. The electric carts’ gross weight when traveled by a user was 246 kg. The small 4-wheel drive electric cart were able to move up only the elevations of 8-10 centimeter when traveled by a user.
