K, once I start building that part, I'll try to see if I can set that up, but use electronics. I was also thinking some sort of chain that hung from a cage and attached to the paintball gun. I would use a screw drive to push and pull the paintball gun, but since it is on that pivot point, it would raise the barrel up or down. To allow for transverse, mount that whole on a setup like your swivel in the middle of that, and have another to push screw type thing to push and pull the whole unit. I think it might be too complicated to get to work, and I don't even know that it would work.
For tracks though, would the v belt thing work? I was thinking more on it; I could just use 2 and connect them in between with whatever I could use for treads, and not have to have the 2 extra wheels for each axle. It would sort of be like your Tyng track system, but using v belts and the pulleys for them, since I definitively can get them before I can get a treadmill belt. Since v belts do hold when tensioned, but slip when they get locked up, that would save on a drive system, so I could use the m1 sprocket type chain for that part.
