So... I have always thought that powered wheelchairs had the potential to make great mobile robot base platforms. They are typically sturdy, well-tested, and designed for prolong (safe) use. Because of their large market (compared to domestic mobile robots), they also benefit from economy-of-scale in pricing (if one discounts exorbitant healthcare markups in the United States). Consider that I can walk down to a neighborhood thrift shop and purchase a used run-of-the-mill powered-wheelchair for $40 (I still kind of kick myself for not grabbing one of the three; I haven't yet seen another materialize) .
Anyway, it appears that as of January 2009, Johnson & Johnson's Independence Technology (a DEKA licensee) is discontinuing production (with service through 2013). This may be really unfortunate for robotics -- domestic mobile robots are just coming into their own, and a base that could traverse stairs would be a real boon. I think it would be a shame if DEKA dismisses the iBOT in its entirety -- dare I say a "failure" on Kamen's part.
Curiously, Dean Kamen came and gave a talk at Georgia Tech a year or two ago where someone from our group asked him about the iBOT as a robot platform. While I cannot recall his exact response, it was something to this effect:
Because of certain FDA certifications / ratings relating to safety, we cannot sell or distribute the iBOT unless you have a prescription and undergo user training. We really wish we could sell them to roboticists, but unfortunately, that would result in loosing the very costly certification.
Costly FDA certifications, indeed... the iBOT retailed for upward of $25,000 USD. Now that it is being discontinued as a medical device, perhaps it can be fabricated and sold for the robotics community instead (at reduced prices). After all, these could be just as useful as the various Segway robotics platforms that DEKA is (gradually) releasing, such as the RMP series of bases (i.e. the RMP 50 Omni pictured below left or the RMP 200 pictured below right).
