AUGUST 21, 2008--For people with physical disabilities, everyday tasks, such as hopping in a car, are often challenging feats. Freedom Sciences (Philadelphia, PA, USA; www.freedomsciences.com) has developed the Automated Transport and Retrieval System (ATRS), a wheelchair system that can be equipped in mid- and full-size vehicles, to alleviate some of these hardships.

The ATRS is designed so that the driver or passenger seat is lowered from the vehicle at the same time a wheelchair storage unit is unloaded from the rear of the vehicle. Once positioned in the seat, the user operates a remote control to guide the wheelchair to the back of the vehicle. As the wheelchair reaches the vehicle's storage unit, the remote is no longer needed and a non-contact Laser Measurement System (LMS) from SICK (Minneapolis, MN, USA; www.sickusa.com) takes over the navigation. With the LMS291 mounted on the docking station, the wheelchair can be automatically situated on the dock and precisely loaded into the vehicle.
