“The Mercenary”, the worlds first commercially available automatic paintball sentry gun. It tracks and automatically fires upon targets on its own by help of a camera and an on board computer. The on board computer processes real time video, obtains targets using motion and color processers, and then tracks them using predictive logic techniques.

Targets can interact with The Mercenary by changing setting options on the on board LCD display, or through an interactive target. The changeable settings include: rate of fire, burst modes, turret aggression, and scenario modes. One scenario includes team based play by use of colored jerseys.

Zero-Op Systems started up in 2007 with the objective to give an exciting technology in the field of robotics and computer vision. In the summer of 2008 they finished building some successful prototypes of the paintball sentry gun, The Mercenary provided ground-breaking way of Paintball, Military Training, and Computer Vision.
