Have a look at this Autonomous Sentry Gun that was built for the Defconbots competition. The site has lots of good documentation of the build. (Article mirror)

More videos after the jump.

“The electronics for this project are going to be relatively simple as well. To control the three servos (pan + tilt + firing), we are going to use the Pololu 8-channel servo controller. Normally we might use an atmega to do the control, however I already created code to control the pololu controller for another project and it’s really inexpensive/easy to use. If it required more complicated feedback or logic, a microcontroller might have been the better choice, but in this case it wasn’t, so the right decision was just to use the Pololu controller. To control the valve, we had two options. One was to use another channel on the servo controller and something like a Banebot motor controller to apply power to the electronic valve, the other was to use the servo that pushes the plunger to push a switch that opens the valve. The ladder option was chosen.”

Thanks Joe.

    […] The sentry gun pictured above was built for the Defconbots Competition where contestants battle it out to see who can build an autonomous device that can shoot down targets in the fastest time. The gun didn’t win, but by the looks of these videos, it seems to work pretty well. And the best part is that the team behind it left a decent amount of documentation on the build. So, if you have some skills, you can be terrorizing kids and small animals around your neighborhood in no time. — Sean Fallon […]
