I was wondering if anyone knows of any type of robot that could be used as a moving target in a shooting range. I know a company based out of Australia has an example (marathon robotics) using segways, but these are neither armored and they do not move fast enough. I need something that could have a manequin mounted on it that could run at 12-15 mph speeds. Ideally the robots would be entirely autonomous and not require a track infrastructure to make sure they remain portable. Any suggestions would help.
