Rotundus Groundbot Robotic Spherical Guardian Video
The Rotundus GroundBot is a unique spherical surveillance robot. GroundBot weighs just 25 kilograms and rolls easily on its special polycarbonate shell. They've done a lot of work on it since its first appearance four years ago.
GroundBot can be operated by hand or it can be programmed to navigate by GPS. It sends back high quality video streams in MPEG-4 from its two pan-tilt-zoom cameras, providing a 360 degree field of vision. GroundBot can move along at up to 10 km/hr and operates for 8-16 hours on its internal batteries, depending on the mission profile.
GroundBot's propulsion system is simple and foolproof - gravity. An internal controlled pendulum is used to alter its center of gravity, causing it to roll in the selected direction. To learn more about it, see this earlier article on the Rotundus spherical robot.
GroundBot is sealed, so it can operate where many robots cannot. It can be used around - or even in - water, and is safe for use in areas where there might be gas leaks.
It appears that the operator can watch what amounts to an augmented reality view, so you can see exactly how the robot is oriented relative to the field of view.
