[TANKS] Re: If you're into automated fire control...
I spoke to a mate ages ago about our tanks and he basically mapped out in his head how to do a gyro-style gun leveling system - point and elevate the gun, engage "auto-leveling" mode and the system (using a gyro/accelerometer) would constantly adjust the gun to keep it where it was pointing even while you are moving the tank. Like most of these things, easy to talk about, something else entirely to implement, and something else entirely again to implement well On May 23, 8:14 am, Mike Måne wrote: > That's an interesting concept...

That's an interesting concept... Perhaps a device similar to real tanks' hydraulic gun-leveling system can be employed. Instead of hydraulics, it could use servos (linear actuators) or perhaps even pneumatic rams. However, the electronics used to fine-tune the aim would be difficult. -Mike M 2009/5/22 HV > > This might be an easier project: > > The human operator points the gun at his target, and the electronics > acquires the target and fine tunes the aim. > > > -- -Mike Måne @ http://moonrcprojects.googlepages.com --~--~-~--~~~---~--~~ You are currently subscribed to the "R/C Tank Combat" group.

This might be an easier project: The human operator points the gun at his target, and the electronics acquires the target and fine tunes the aim. --~--~-~--~~~---~--~~ You are currently subscribed to the "R/C Tank Combat" group.

[TANKS] Re: War in the Woods reconnaissance
This looks like the way to go. I doubt we will be operating in very high winds. I just wonder whether it will stop (or rather slow down sufficiently) paintballs? It is very light- 80 gm/sq m is exactly the same weight as photocopying paper. Our local p-ball place uses netting whichis thicker I'm sure but that's for permanent erection. It'd be worth e-mailing them. Has anyone in the group tried using netting? I have a collection of aluminium poles left over from various trailer- tent awnings (now departed to trailer-tent heaven) which are probably suitable for poles. DATES: How about 5/6 September here in Surrey guys? I'm warming up the barbeque!
