Welcome to Project Sentry Gun, home to the most versatile sentry gun on the web!
Now in use on six continents!

This sentry gun autonomously tracks, aims, and shoots at targets, using:
  • An airsoft or paintball gun
  • A webcam to find targets
  • A computer to process the video feed and aim the gun
  • Servo motors to physically aim the gun and squeeze the trigger
  • A sturdy tripod base
  • A microcontroller to interface between the computer and the servo motors
  • Fully open-source code
  • Lots of camo paint
 The end result is a paintball/airsoft spewing robot, that can turn the tides of any match. 


     The Eugene's paintball sentry, Andrea's airsoft sentry, and the Gladiator airsoft sentry.
