On Friday CMU announced via press relase the creation of the "Ballbot" (original, I know). It’s a robot that dynamically balances on one steel ball. It was picked up by several robot websites and was also featured on RocketBoom.
That’s all fine and good, until someone cries "fowl!"
Theo goes on to say:
Translation: It’s not that hard. A PI controller takes about four lines of code, and experimental tuning involves grunt work, not real science. Here is a link to the IMU they use.
While I’m not sure if I’d be as harsh as Theo is with them, I definitely don’t think it was worth all the hype or the press release. Come on CMU, show a little humility!
Update: Theo, made some good comments below.
