Robot surveillance balls. Sounds great. Partner them with computers and artificial intelligence. Nothing to worry about.
This is Guardbot, a surveillance robot that's able to manoeuvre on any terrain, even having the ability to swim. The device comes in a variety of sizes, ranging from as small as 5 inches to a model that is 7ft in diameter. Guardbot is fitted with two surveillance cameras, a batter that can last for 25 hours, microphones and GPS, allowing it to be controlled via satellites as well as remotely. It's currently still in development and the military are looking into using it for future deployments.
Shocking that the military is looking into them.
