The Rotundus GroundBot is a dual-camera security bot that returns 3D video feeds to a security team located nearby. I think I'll call him Wheelie from now on. Oh alright, Wheels it is.
Ideal for environments with plenty of flat spaces, like airports.
The slick rubber surface provides smooth sailing and speeds of up to 6mph on flat surfaces.
Alternatively, those little nubs help the GroundBot wheel uphill.
