NSF backs development of laser-guided robot wheelchairs
It's been well over a year since we last saw the laser-guided, self-docking wheelchair developed by folks at Lehigh University, and now the team is back with an altogether more ambitious project. According to associate professor John Spletzer, the recipient of a five-year CAREER Award from the National Science Foundation, the goal is to "extend the autonomy of the wheelchair so it can navigate completely in an urban setting and take you wherever you need to go." This will be done by equipping robotic chairs with laser and camera sensors (which the team developed for the 2007 DARPA Grand Challenge) as well as exhaustive, Google Street View-esque maps of the city where they will be operating. Of course, these guys will be operating in a busy urban environment, so in addition to large-scale 3D maps, they must be equipped with motion planning features for operating in dense crowds and a changing environment. It's too soon yet to say when these things might become available commercially, but if you're a resident of the Good Shepherd Rehabilitation Hospital in Allentown, PA, you might have your chance to test one soon enough.

ATRS to make entering / exiting vehicles easier for handicapped individuals
While there's certainly smart enough wheelchairs to get you around town without mauling a lamppost or taking out a crowd of bystanders, a Pennsylvania-based team has developed a system to get wheelchair-bound individuals in and out of their cars a lot easier. Engineers at Lehigh and Carnegie Mellon have partnered with robotic startup Freedom Sciences LLC and Freedom Lift Corporation to unveil the Automatic Transport and Retrieval System, which will supposedly "enable wheelchair users to drive while sitting in standard automobile seats that meet federal safety regulations." Currently, motorists are forced to use cumbersome, bolt-in attachments that typically require heavy modifications to the car in order to operate; the ATRS system, however, uses remote controls, wireless technologies, and "lasers" to assist drivers into a standard seat, roll their wheelchair "autonomously" to the loading dock, and close up the rear door, all while parked in the driver's seat. Sensational as it may sound, the system doesn't come cheap (nor with a wheelchair), and will cost handicapped individuals (or insurance companies) between "$15,000 and $20,000" when it goes on sale next spring.
