Children with various genetic disorders often have limited walking ability, requiring them to use wheelchairs. Manual wheelchairs are hard to push which makes children to become tired and motorized wheelchairs are expensive and heavy.
A team of five undergraduate mechanical engineering students at Brigham Young University have designed, manufactured and constructed an inexpensive, lightweight, motorized wheelchair specifically for children with walking disability.

The whole device weighs just over 20 lbs. Less than $500 used to construct the wheelchair using off-the-shelf components, a considerable savings compared to commercially available motorized wheelchairs.
The students will soon be releasing the list of the parts and the construction plans for the wheelchairs, allowing anyone anywhere to build inexpensive motorized wheelchair.
