Look at the wheels on this KUKA omniMove Mobile Robot
I got a chance to see a bunch of KUKA robots up close when I toured the Audi factory in Germany. These robots are amazing. Extremely precise, very efficient, and surprisingly quiet. But I didn't quite get to see any KUKA robots on this sort of scale.
The KUKA omniMove Mobile Robot shown here is used to move large portions of Airbus' A380 fuselage during manufacturing. These giant moving platforms are able to maneuver in extremely tight factory spaces thanks to special wheels that "turn" the platform by moving laterally.
