I’ve been looking at different robots but I’m still a bit puzzled on how I can do this. Anyone know how I can make a mogo tilter on the back with a pneumatic piston and a motor? We already have a fixed pneumatic clamp but are trying to make it tiltable. Thanks
A picture of your existing clamp would be very helpful for helping figuring out how you need this to work. I have a few ideas for you but they are all dependent on what you have now so if you can send a picture of that I’ll try my best to help.

Hello there i ran into this issue too where i had an extra motor but needed a back clamp/tilter. I managed to come up with this design, its a bit bulky and you might have a hard time fitting it on your robot if you dont have much space but this is just a motor and it can clamp and tilt a goal back and hold it there. I tried to get different shots of it. Hope this helps!
Ty for the pictures I’ll seeing if I can do something similar to it
Could you send a video of this in action? I’ve spent like 5 minutes looking at this and I still don’t understand how it works lol. Its a great design and really unique, I’m really impressed and also very confused on what is even happening so great job figuring out how to make that work lol.
I could try to Monday morning if i can remember but its basically 2775j’s mogo mech but with a motor, so when the gear spins backward the standoff pulls the clamp shut then proceeds to pull the goal back. Thats the best way i can try to explain it but if i can remember i will record it in action!
I forgot to reply to you lol
Ok I looked at the pics a bit more (thank you for taking so many I wouldn’t have figured it out without all those different angles) and I think I understand how the clamp works now (it looks like the motor drives 12tooth which spins the green gear which pulls back the standoffs that are on the clamp and pulls the clamp down), but I’m still confused as to how the tilting part works and is set up, by spinning the clamp and latching on to the mobile goal does it also tilt the clamps part back? Is that what the rubber bands do? I think I have an idea of how the tilting part works but I’m not sure how exactly it functions (I have an idea of where it tilts and what tilts it I’m just not sure how it tilts)
Alright so on the 3rd picture (the one facing the clamp head on) you can see the stand-off below where the clamp part pivots. This standoff has bolts screwed into it through the c-channel which serves at a pivot point. So after the clamp closes on the goal and has no where else to go, the gear continue to spins and pulls the whole clamp itself back which is where it starts to pivot. The rubber bands are just there to support the motor so it isn’t holding all that weight ya know to kind of help overheating.
bruh forgot to directly reply again.
Edit: nvm i’m just dumb lol i don’t talk much on here
Ok thank you! That’s kind of what I thought it was I just wasn’t completely sure. I think the rubber bands threw me off, but the reasoning as to having them makes a lot of sense. Do you think the rubber bands would be necessary to have if you just set the motor stopping to hold inside the code? I would probably still put them there just to help the motor but I’m curious as to if they would be completely necessary.
I have the motor set to hold in the code. And even before the bands, it held completely fine but the bands are really just there to help the motor last longer. But to answer your question, no they aren’t necessary.
Do you have double acting pneumatics? If so you can definitely make the robot mesh that 2775 has, as the video explains it well enough.
If not I’d suggest making a clamp like the Pink Unicorns (2145Z). My team made a modified one inspired by theirs and it works pretty great.
Honestly, I didn’t use cylinders because I had the motor to spare and I’m stubborn and didn’t want to waste it. But a cylinder mogo mech would probably be way better anyway
Sorry to keep asking about this design, but im just curious as to what these to bars that stretch out from the bottom are for
It doesnt look like they are attached to anything important or hold anything together so im just curious as to what they’re for.
Lol its ok, so basically when they weren’t there we would try and open the claw and the whole thing would just tilt forward. Plus when we tried to back into a goal it would tilt forward too. So those bars are there for the whole thing to kind of fall back on. Let me know if there’s anything else you’re confused on, I’d be happy to help!!
This bot looks familiar
Good to you see on the forum alliance partners!
Thank you for all the help and sharing your great design! I would never have thought of something like what you have so thank you for sharing it.
