Another use for a robot, inspecting for bombs etc, this is the general-robotics Ferret. I find the name of the company interesting it’s turned up in SciFi forever, following General Electric, General Motors, General Mills, General Atomic, etc, etc, it became a claim on greatness then a cliche. The parent company is in electrooptics and it’s influence can be seen in the video glasses. Does not take away from a great idea. I wonder if the inventor was watching his Rumba vacuum under the couch when he had the flash?
