Because it's always a good idea to have wall-climbing robots ...
"Oh, hell no," said Will Smith in "I, Robot."
... Disney decided it needed one of its own.
And, no, we're not talking about this robot.
"WALL-E," says WALL-E.
Disney's wall-climbing robot is called VertiGo.
It climbs walls with the help of two propellers on its back.
The propellers push the bot against the wall; its wheels do the navigating.
That's different from the lizard-like technology Boston Dynamics used.
Or the suction tech used in the Otto robot from California Polytechnic State University.
Wall-climbing technology of any sort helps robots travel in challenging environments.
So why does Disney need a wall-climbing bot? We're still trying to figure that out.
