DefconBots is returning again this year with their shooting gallery robot competition for Defcon 16. They’ve decided to leave the rules unchanged from last year. It’s a head to head competition between fully autonomous guns. The first gun to shoot all the targets on their side of the board wins. The rules aren’t very strict on design; as long as you use nonlethal nonmessy amunition and include a safety switch you’re pretty much good to go. The DefconBots site has a reference design to put you on the fast track to competing. Defcon 16 is August 8-10, 2008 in Las Vegas.

[Colin] sent in his prototype for the Defcon bot contest. The performance of the bot in the video is impressive. Hit it after the break. His build looks clean and simple – he even managed to score some sponsorship in the form of pololu servo controllers. Targeting the moving white sensor reminds me of the old MacGuyver episode with the lethal heat seeking robots.

If you’re working on any attack bots, feel free to let us know via the tips line.

Update: I woke up to realize that I forgot to embed the video. It should work now.

[Jared] over at inventgeek.com remembers to think of us whenever he finishes up one of his projects. His latest is an USB Airsoft gun turret based on one of those USB nerf dart turrets. Hrm, this could make a decent base for a defconbots entry. It sounds like he’ll be building an even deadlier expensive version later on.

Don’t forget, December 25th is the deadline for your Design Challenge entries!
