*HELP*Epoxy bonding or glue used on the robot

[Jecht22]

I can't seem to find any rules while searching the rulebook regarding epoxy or glue. We wan't to bond belting around our lazy susan but don't know exactly if this is legal. I vaguely remember past years there has been strict rules around epoxy, glue and tape but I am not 100% sure on those rules this year

There are no rules against using adhesives so long as they don't get on game pieces or damage the court.

[Justin Stiltner]

It is typically considered a fastener so no worries there. Make sure you rough up the surface of whatever you are gluing to so the epoxy has some help in gripping the metal.

Try double-sided tape. Think you will find it works out well....

Epoxy and the belt may not be the best. Test a strip first. Thick CA may be better.

we did the exact same thing... it's not at all prohibited

epoxy is stronger, and has a slower drying time, allowing you to shift the belt into position. ca is also more brittle, wheras epoxy has some flex to it

I agree. CA might do better on the belting. To answer your first question, you can use as much epoxy, CA glue, 2S tape, etc. as you want.

We used this:

for our robot more than I would like to admit in 2011. We never could fully take it apart.

Interesting. I'm tempted to look into the use of this. Curious, what's an example of your application. The website states that it is

really strong tape, also known as VHB tape, is an alternative to traditional mechanical fasteners like screws, rivets, bolts, and even welding.

Would you say that is an accurate statement, or did you use it in place of duct tape or other after fabrication fasteners?

We use double-sided tape to secure electronics much of the time, and we got ahold of a few different kinds of VHB tape this year. The one used in the below picture wasn't the type composed of foam, it's extremely thin and transparent. I haven't found a link to it yet.



The Crio was taped to the crossbar on the underside of the robot. The bar was pocketed and the remaining material was only slightly narrower than the width of the tape (about 3/4 of an inch). If you look at the pattern visible beside the Crio, you can probably estimate the total amount of tape we used. In our testing before the final mounting, it took a significant amount of force to break the bond even without even scuffing the anodized finish of the bar. It gave us no problems through the entirety of the season and the weekend in New Hampshire.
