Little toy robot excels at walking straight ahead.

Go, little robot, go.

It’s got these batteries that never wear out, like in some commercial. And when it hits a wall, it just keeps walking.

Walking in place. It can do this forever, face up against the wall. Walking is what it does.

Walking, walking. It can do this for forty, fifty years, at least.

Then it gets turned around.

Boy does that feel good!

Go, little robot.
