Father invents power wheelchair for his son

“We wanted Alejandro to have a power wheelchair. We wanted him to be able to move through the world by his own volition and it’s clear that the ability to independently explore his environment is important for his cognitive development on multiple levels. We tried going through the typical process of obtaining a power wheelchair but met numerous obstacles. (...) While looking for motors and wheels on Ebay I stumbled across a used adult chair for relatively cheap. I decided that starting with this was a significant head start on the project and was well worth the money. I purchased the wheelchair with the intention of using the motorized base and controller and then add new seating and a customized access method. I also purchased a wheelchair programmer, a device that allows you to configure and modify the wheelchair’s internal drive and control parameters”, his father explained.
