Robots on Wheels!
Ha, this is so pointless at the moment, but still kinda cool I suppose.
Explaining why Hitachi's Emiew used wheels instead of feet, Toshihiko Horiuchi, from Hitachi's Mechanical Engineering Research Laboratory, said: "We aimed to create a robot that could live and co-exist with people."
"We want to make the robots useful for people ... If the robots moved slower than people, users would be frustrated."
It moves at a little under 4 miles an hour. Looks to me kinda like a Segway on wheels.
