That reminds me of another issue: We originally had our battery resting on two bolts. Probably a bad idea, because it shorted and caused the battery to heat up melt the blue plastic insulation.

We used the pivot bearings in our robot at one time, are you using them as suggested in the instruction manual?
First off, great idea! (battery holder) and wise warning

Yes I'm using the pivot bearings as instructed, maybe an isolated incident?

Re: [FTC]: Common failures with TETRIX

Perhaps. Do you mean the screw went all the way through the center of the bearing? Or through the small holes on the servo mount? None of our bearings had that problem, and if all of yours did that would be a huge coincidence.

Re: [FTC]: Common failures with TETRIX

I actually have a few unopened packages of bearings i haven't tried yet. So it could really well be an isolated incident. For clarification, the screw went through the bearing and metal but wasn't able to make it through the servo bracket. I'll post a picture perhaps (lol if I kept the "mismanufactured" bearing set)

Re: [FTC]: Common failures with TETRIX

The pivot bearings are useless for everything EXCEPT what they're used for in the manual. Most metal is just way too thick for the length of the screw; it only really works with the really thin stuff. It's sad, because there's so much we could have done with it...

Re: [FTC]: Common failures with TETRIX

I think I saw the answer already, so forgive me for asking directly -- will the servo burn out if stalled? We are using it to run our claw & depending on how the ring nests it may not close entirely, stalling the servo. I am thinking we will need a spring relief for this. What do you all think?
