The typical security robots that you see publicised these days are usually from japan or korea and basically is like a R2D2 that travels on 4 wheels. Rotundus is a swedish company that thought out of the box and introduces a security robot that is an entire sphere.
What's innovative about this robot is its propulsion system. It is powered by a pendulum inside the sphere. When the pendulum is displaced from the center of the sphere, the ball will move along the direction of the pendulum. As such, it can move in virtually any direction.
A sphere shape means it's fast too. Little point of the contact with the ground means little friction. It can also tackle any terrain from snow to grass to concrete. No need to get stuck at corners either
This robot was developed by Ångström Space Technology Center, part of Uppsala University, Sweden, and meant to be used in space. But people also realised that it can be used as a security robot back on earth. Plenty of space inside the sphere to put cameras, microphones and various sensors to fulfill its purpose as a security robot. All you need to do is set its patrol route, and it'll follow by using GPS.
It's still in prototype form though, and the finished version would have improved GPS, radar, alarms, and a better powered pendulum to enable it to go upslope. That's alot of improvements that need to be made, but the basic concept shows a lot of promise.
Now imagine this as a gps-enabled bowling ball and the things you could do with it. Perfect score!References
