Hi my name is Sai from hill middle school Team B and I am here to ask if somebody knows anything on how to build a Mobile Goal Mechanism. I have been searching Vex Forums and YouTube for around a week with no results on this topic and it would be very helpful if somebody can help me in this situation.
Post a picture of your robot, so we could see how it might fit onto it.
Generally, good mogo mechs are simple clamps powered by 2 pneumatic pistons that push forward on the top part of a metal bar so that the lower part is pulled towards the bot, which would clamp a theoretical mobile goal in the process.

As a guide of course no one will tell you how to build it but there are people demonstrating it on YouTube. So I really think you didn’t bother to look.

Our team is the only team with a Pneumatics and we only have one because our school generally does not buy things for us. So is there a way to make it work with only one pisont and I will send the picture as soon as possible.
Yes, it is very possible.
Again, we’re not here to build for you. Make sure to keep your search broad, and also just take time to just play around and experiment yourself rather than relying on already-designed ideas.

No, I did check YouTube but non of those where really helpful to me because most use two pistons or just don’t explain it really well.
Adapt a design it’s not very hard to turn a two piston mech to one. The same concept applies.

Okay, thank you for the advice.
We use one piston and it works great. So it doesn’t have to be two.
Hi, I have also run into another problem with my Mogo Mech. When I finished the code and everything I clicked the button that sent the air out and it didn’t work. It just releases air for some reason. Also, another problem is that our single-acting piston. It has the fittings in the back. We have had a problem with mounting the front of the Mogo mech to a piece of C-channel because we don’t have the mounting part. It would be very helpful if we could get some help. Thank You.
For your air problems, it sounds either like a leak or faulty parts. You can fill your tank using an air pump, then slowly monitor the PSI of the tank to see if it drops over time. If it does, you can then search for a leak somewhere on your pneumatics.
For your mounting, we also ran into the same problem. For us, we cut 1x1 L channels into 1 long bits to form 90 degree angles, which can then be put onto a C channel to act as a piston mount. You can then run a screw through to use a screw hinge.
What screw would I use.
@T1T4N11 The way that my team does it is that we put multiple hex nuts on the threaded bit of the rod, and then screw on a collar, leaving space for a screw to run through the collar. We then tighten up the hex nuts to lock the collar in place. I’d post a picture, but I’m at an FFA contest today. I’ll post one tomorrow if I can remember to.
