For the power supply, you should use the computer's power supply, but it will require some electronic magic because it delivers 12V and you need 7V or whereabouts for servos. A LDO regulator should be employed if the board you decide to use doesn't use one.
Arduino!Computer USB > Arduino > peripherals (bluetooth, turret, etc etc)You can simply search "arduino bluetooth" or "arduino servo" and get tons of examples, so if you can code reasonably, it shouldn't be too bad.
Axon!Yeah... we could do this all day and not get far.Best advice you can get about choosing a controller: have a look at the Axon (a helluva lot of functionality) or the Arduino (very good price from what i hear. There are other cheaper controllers on the market if these are too much for what you need. After you did some scouting, decide for yourself what works for you. Don't ask which one you should use because you won't get a clear picture. You should ask what features do individual controllers have to offer.For the power supply, you should use the computer's power supply, but it will require some electronic magic because it delivers 12V and you need 7V or whereabouts for servos. A LDO regulator should be employed if the board you decide to use doesn't use one.The turret will most likely be powered by a servo, which plugs directly into most boards. Also, the Bluetooth device plugs into an UART port (so your controller should have at least one).For the motion part, i recommend DC motors because i don't think servos would be suitable for movin a large computer around. To drive DC motors you need H-bridges. You could build your own (some very good links on this forum, and Google produces good results as well), or you could buy one (Sabretooth would be a good place to start).That should get you moving in the right direction. I don't know how good my ideas are, but i'm sure others will have a word to say about them

I believe if you plug into the 5V and 12V connections you get a 7V difference in potential. No LDO regulator needed. Good luck with your project. I would love to hear about your progress. I'm in the process of building a treaded chassi with a defender airsoft gun mounted on top. I've asked questions here on how to connect a laser to a microcontroller and power the firing motor.Conscripted
I plan keeping the gun detachable so the gun is going to retain its own power supply along with the laser. So I can't help with hooking up the firing motor laser to your microcontroller. I just want to be able to remotely fire the gun and turn on the laser. I do plan on doing a full picture/video build so you will be able to keep track of it.
You had suggested a servo to control the turret pivot, the gun is roughly 6lbs unloaded would that be too much weight for a servo? Would I be better off using another dc motor?
