Sogang U's 21st century robo-walker

Dude, forget that crappy piece of plastic and aluminum with the cut-out tennis balls you put on the bottom, Sogang University's elderly walker-bot is where it's at in 2005. We wish it wasn't such a unitasker — for example, it might be nice if the robot could also help the elderly dance like in that terrible, terrible commercial — but stick this in your pipe and smoke it, Joe Engelberger. We kid, we kid.
