Jtkthx” has unveiled a new version of his home-built robotic sentry gun. Video after the jump.

A webcam first takes a picture of the environment in front of the tripod. A computer running Java then interprets that image, deciding on a target. Based on predictions of movement and servo calibrations, the computer sends a signal to a Phidget servo controller, which then moves the four servos attached to an Airsoft mini MP5. Servo 0 is the X (or pan, yaw, whichever you prefer), servos 1 and 2 are the Y (or pitch, or tilt), and servo 3 pulls the trigger
