Motorized wheelchairs were a huge development in helping disabled/old folks get around. The problem? What if grandma pushes the gas a little too hard and careens off the stairs? Or into traffic? Or down a hill?
Case Western Reserve University students are working on a solution: robotic wheelchairs which filter your requested movements and check for safety hazards. Cool, right? There's more. They're also working on voice-command technology, so gram could say, "Take me to the fridge," or, "Open the fridge," or, "Make me a sloe gin fizz already, dammit" and her wheelchair would do it. OK, maybe not the last one, but Case is definitely working on requests like the first two.
