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.

Researchers show off laser-guided wheelchair that docks with vehicles
We first heard about this laser-guided wheelchair way back in 2006 but didn't really have much more than promises from the team behind it about exactly what they had in store. As New Scientist reports, however, it seems that the folks from Lehigh University and Freedom Sciences are still hard at work at it, and they're finally showing off some of their progress. The wheelchair is apparently still not entirely automated though, with it needing to be driven to the rear of the vehicle by remote control, after which the on-board LIDAR system kicks in and loads it onto the lift all by itself. Not surprisingly, the estimated price for the eventual commercial version has also gone up since we last heard from the team, with it now set to demand $30,000 (as opposed to $15,000 to $20,000) when it goes on sale later this year, assuming it gets the necessary FDA approval. Until then, you can head on over after the break to check it out in action.
