The Network-Centric Applied Research Team (N-CART) is continuing work on a project known as the Network-Enabled Powered Wheelchair Adaptor Kit(NEPWAK). We have introduced techniques for modifying powered wheelchairs to allow tele-operation over the Internet. As a prototype version, a wheelchair was equipped with a low-power laptop computer, CCD camera and wireless network card. Custom circuitry was supplied to allow control signals to be sent by the laptop to the chair’s control circuit. The laptop acts as a server allowing network clients to gain access through a custom control interface that includes a video feed from the wheelchair.
