if you have motors outside the frame how do you have to hold the wires and how must the pneumatic pistons be attached?
Could you please be a bit more specific? It’s completely unclear what exactly you’re asking.
will have to send to you through you’r email. my computer will not let me put the picture up
Upload it to imgur.com, copy-paste the image URL and use the tags. Ensure that the link inside the BBCode ends with .jpg (i.e., that it’s the image location and not just the imgur page).

If you can put it in an email, you can put it on imgur.
Also, in the future, you should post this sort of thread in the technical discussion forum, not the general forum.
I think I got the arm hanging and the pneumatic
While a picture is certainly likely to help us understand what you’re asking, a few more words might be useful in the meantime.
What does “outside the frame” mean when you say it?
What is the function of the motors you are asking about?
To what are you trying to attach the pneumatic “pistons”? Do you mean pneumatic cylinders, or are you trying to refer specifically to the end of the moving rod?

Where the blocks are is where the bumpers will be

The motor turn to pick up the ball

The pistons are used to pick up the arm with the ball and lower the arms to get the ball
Um…yeah, go ahead and try to upload a picture somewhere we can see it. Your Gmail link won’t work for anyone who isn’t logged on to your Gmail account.
I would be cautious about that motor placement, but for running the wires I’d recommend the usual judicious use of zipties.
For attaching the pistons, at the rod-end you’ll probably do best to use a standard bimba rod-end clevis, and at the rear end you’ll either want their pivot brackets or you’ll want to push out the pin that comes standard (by means of a large bench vise - I’ve tried a two ton arbor press to no avail) and use a bolt.
thank you
I don’t think there are any specific rules that require you to attach your wiring in any particular way. If that ball pickup assembly starts the match inside the frame perimeter, then you can do it pretty much however you see fit.
You’ll want to make sure they don’t pose an entanglement risk to other robots, and that they aren’t prone to being pulled out or tugging on (and breaking) the motor’s electrical terminals. It might even be a good idea to include some sort of guard around the motor itself to keep it from accidental damage.
I still don’t understand what you want to know about mounting the pneumatic components.
If I’m seeing this correctly, it appears this is a ball collector hanging outside the front frame perimeter (when deployed).
In addition to the high risk of your wires being caught and ripped off the machine, I’d venture to say your actual gear motor assembly might not last through more than a couple matches before getting destroyed in a side-impact collision with an aggressive defender.
I’d strongly suggest some additional protection for your mechanism and the attached wiring.
I’m worried about your cylinders bending. If a robot traveling 15 fps comes crashing into your arm, do you think the cylinder will survive?
I predict many broken attachments this year.
when the arms are not being used the arms are in the frame and up.
Right, but when they are “being used” is exactly when you’ll be attracting the attention of the aggressive defenders.
At a minimum, it would appear to be a relatively straightforward change to put the gear motors on TOP of the ball rollers instead of down at the bottom. They might have a better chance of survival up on top. That is…IF there isn’t some kind of space constraint in the retracted position with the motors on top.
Alternative: Bring 45 pounds of extra ball collectors. You’ll need them.
