I don't see how the drive mechanism is any different than a Sphero toy, but I like the dual gimballed camera mechanism. I assume the cameras are independently controllable in pan and tilt, like a chameleon? If you could point them in the same direction, you could probably get reasonable stereo vision to a remote operator.
This is an interesting alternative arrangement for a security patrol device, and it would appear to have avoided quite a few of the common challenges with it's unique form factor. But it would be fairly simple to neutralize with a method similar to the one used by biologists for capturing skunks. But otherwise it is quite an intersting package. A smaller version would probably sell very well as a high-class toy. Just think, a two inch model could probably go almost anywhere and not be noticed. But scaling down might be quite a challenge.
"The patented drive-mechanism uses a motorized pendulum to propel the Guardbot by changing the center of gravity for back-and-forth movement, as well as 360-degree turns" sounds like an ingenious way to take advantage of a sphere's capability for directional momentum. It reminds me of a hamster ball with a hamster in it - the hamster's center of gravity affecting the ball's motion and direction while moving about the floor. I am wondering if any of these are in service yet - the variety of payloads make the extremely versatile and I could see them being used in many different applications.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
