The reason we want to use a wheelchair system is so they can use both a traditional wheelchair, by stowing the pedal system, and the pedaled system. The current pedaled system on the market does not allow for this and patients knees are kept very high up due to the pedal system. Because of this they need two systems, the pedaled and the non pedaled. We're looking to combine the two so the patients won't need to switch systems if they want to use the pedals, they'll just use the linear actuator system to bring the pedals out and then go back to the hand moving system when they are done. This also lets them pull up to a table, which current systems do not.
Hope that helps!
