[CONCEPT] Vertical stabilizer (without a gyroscope)

[Tommy Styrvoky]

I was wondering about making a self leveling gun that would keep the current position of the barrel if the vehicle's hull wasn't level with the ground.

This concept uses a servo attached to a gun carriage with some gearing to allow the gun carriage to "float" freely when the ground angle is changed. A counterweight attached to some gearing on the rechargeable battery box allows for 15 positions of the counterweight, The servo mimics those positions and compensates the barrel by moving the gun up how many positions the counterweight has moved. The elevation mechanism for the gun is attached to the gun carriage.

Here's a image of what I mean, I don't have the parts to test it, but if someone is willing to try it would be helpful.

That would probably work very well! As long as you can fit it all

I think however it will be a little jerky, as the servo will move in 90/7 degree increments, unless you gear it. Not having the rechargeable batterybox myself, I wouldn't know how "hard" the speed dial is, nor whether it is free moving like the dials on the speed remote controller, or fixed with +/- 7 steps

EDIT:

Concidering your previous tank MOCs, space might not be such a problem

the sevo and counterweight would probably be geared down to move 30/7 either direction and I'm posting this idea for this tank http://www.eurobrick...showtopic=96453
