The Segway RMP: Magic carpet ride
Sadly, this odd platform wasn’t working today due to firmware problems. However, as you can see from the video, it’s basically a moving platform that can move in any direction without turning. You can basically turn at a 90 degree angle while moving forward and the thing runs as if it were on rails.
It’s a Segway prototype right now and can be embedded in almost any configuration, including this odd table thing that never falls over. The devices move so smoothly it’s eerie.
