Marathon Robotics has developed a robotic training system for the Australian special forces. Targets are mounted on Segway Robotic Mobility Platform (RMP) vehicles which are controlled by a central computer system. They can, for example, be programmed to scatter when a shot is fired, just like you would expect from human, making it much harder for the sniper to take out the next “terrorist”.
Personally I think this is the best possible use of these damned devices. Nothing would give me more pleasure that shooting a Segway in the ass!
