My team has an idea for a mogo mech that we’re building. It uses two pistons that aren’t yet attached. The only problem is that we need something that could be facing upwards to that the piston does not just move with the mogo mech.
If you know if anything like this that could rotate, let m know and maybe link the page to the vex website. (Doesn’t really have to look like the sketch, that’s just how I imagined it.
To clarify, you need something to act like a ball joint at the end of your piston?
Something like that, yes
you can do something like this with the old steel shaft collars with the screw removed. With the screw removed thread the threaded part of the piston into the spot that screw would go. Then attach that shaft collar using a loosely tightened screw and nut combo were the shaft would go to attach the shaft collar and piston to the side of the c channel. I will try to get pics of hol mine work up here soon but this works wonders.
If you use a the newer pistons that vex is currently selling then you could use the threads on the end of the rod to go into a metal lock collar then put that lock collar on a screw pivot that is mounted directly to the clamping device.
Instead of attaching your piston rigidly to the mechanism (as seen in the pictures you provided), you can attach the piston to an axle that the piston (if it weren’t attached) would swing freely around while the mechanism to be moved would be attached rigidly to the axle. I know this explanation can be confusing, so here is a diagram:
Note: The part labeled “Part that allows piston to spin if held only by axle” can just be a small c-channel or something like that with the axle put through its holes (with bearings of course).
