"One time we dropped it out of a helicopter from more than 100 feet," one of the designers tells me. "The worst that happened was that one wheel was slightly damaged so it wanted to drive a little wobbly. But it still rolled."
I'm at AUVSI's (that's the Association for Unmanned Vehicle Systems International) Unmanned Systems North America convention at the Recon Robotics booth, checking out the company's Scout reconnaissance robot, a tiny two-wheeled system weighing just more than a pound. It's a diminutive machine, about the size of a tallboy beer can. And I've just been invited to chuck it over an eight-foot wall.
