Critique my gripper design please

Unlike the robot code, the physical parts cost money which puts a lot more value in having the fewest iterations possible. Making small changes also takes much longer to implement than guess-and-checking a few variables.

Idk, I have seen programming errors cost a lot of money. Rapid iteration without considering consequences can lead to… Learning experiences.

But yes there is definitely incentive to not iterate on minutiae when it comes to physical prototyping. Keeping in mind there is a lot to learn from modifying a physical prototype to get it to perform better, often this costs very little. Not just finding raw performance, but understanding physical material properties and limits of robustness.

Print an adapter to do what?

Go from ultraplanetary output to a pulley, or a hex shaft.
Example of one on 112’s gripper:

Something like this but 3D printed?

Last season our gripper relied on two UltraPlanetary 1/2in Hex Adapters which we 3D printed out of PLA. We didn’t have to replace any until the end of our third competition when one finally broke after a hard impact against the loading station. Our adapters were slightly modified to be more rigid by thickening the connection between the mounting face and the shaft.

This looks awesome. Here are a couple of thoughts I had. I very quickly skimmed through the thread so I am sure I will be repeating a couple of other suggestions people had. Also some of these things are important and I want to make sure the are highlighted.

Use bearing retention hats from TTB or something similar to retain the bearings.

Add some sort of spacers to hold the plates together.

I would look into using the round bands to run the wheels instead of belts, like 1678 and a couple other teams did this year. Just to save some space and make it a bit thinner.

Why not use ultraplanetary gearboxes on the neo550’s rather than changing the ratio externally? Would save space and weight.

I would take out the back pockets by the neo550’s. That’ll take about two hits before it cracks off. If you are mounting the intake the way I think you are mounting it, this is especially critical.

I don’t know what this intake is going on but you could build in some level of suspension into your arm or do what 2075 did and design it such that when you are going to intake on the double sub, your bumpers smack the wall before your intake does. This is probably going above the input that you wanted, but I thought it would be something to think about. And it is also assuming you are going for the double sub.

Overall this thing looks awesome! I’m excited to see how it turns out.

I would highly not recommend using the round polycord. We used it in 2022 and had a ton of problems.
