Groundbot from German firm Rotundus can be remote controlled or programmed to navigate by GPS.
Groundbot can also travel at up to 6 miles per hour and last between 8 and 16 hours depending on the mission. The rechargeable Li-Ion battery can be completely recharged in 3-4 hours.
Containing two pan-tilt-zoom cameras, Groundbot can stream high quality video.
The round sphere housing the robot is sealed and can float on water. The robot is also virtually silent and would probably make a good surveillance robot. This is probably due to it’s pendulum driving mechanism. Groundbot can also be outfitted with a variety of sensors such as gas, heat, radioactivity, humidity.
This robot looks like it was designed by Braun or Dieter Rams.
No word on price, but you can contact Rotundus through their website.
