Tim Lexen, an engineer in Cumberland, Wisconsin, came up with the idea of a robot riding around on helical coils parallel to the ground, and then built a radio-controlled prototype in his spare time.
It runs very well on grass, sand, gravel and other outdoor surfaces," New Scientist quoted Lexen as saying.
But the prototype has trouble gaining traction on surfaces like polished wood floors, and Lexen plans to add motion sensors so that the robot can orient itself.
