Robotic Paintball Sentry

Shoots things!

Hey Guys,

Figured I'd show off my latest robotics project, this is a Robotic Paintball Gun Sentry. It's using a pair of RX-64 Dynamixels for the pan/tilt, with some major modifications to the default base platform. The entire base was designed in Autodesk Inventor and cut from 1/4" Black ABS on a lasercutter CNC. Onboard brains is an ArbotiX Robocontroller, which is programmed in the Arduino IDE. It uses a relay hooked up to a digital output to 'trip' the electronic firing control board that I yanked out of the paintball gun. Currently it's remote controlled using an ArbotiX Commander handheld controller and a pair of Xbee wireless radios, but a camera has been added and am working on a fully autonomous mode (which will also include an onboard laptop).

Awesome project!!

'I am very impressed, and the camera is going to make this even cooler.

Nice work man!

Thanks! I actually have such a sensor and have used one mounted on a similar (smaller) airsoft turret. Hit the target sensor and it disabled the turret for X seconds. 

Code is available here, though note that it uses some custom libraries (all available for download from Vanadium Labs' site)





Very nice -- the workmanship looks top-notch.  All it's missing is a sensor to tell it when it has been disabled (although that might not make much of a difference during play, as it might be easier to shoot the operator).

The PDE file (the Arduino code) would be interesting to me, if you're willing to show it.
