A robotic wheelchair called the ROLY -robot assisted learning for young drivers -has been developed at the University of California by researchers. They are currently testing it in a group of nondisabled children and one child with cerebral palsy, hoping to lower the cost of teaching children with disabilities how to use wheelchairs. It will allow children to learn at their own pace with less assistance, substantially reducing the costs.
A photo showing how it works can be found here.
Instructors can provide assistance to the children, allowing them to progress at their own pace.
