Let's See Your Robot's Battle Scars

[Sparky3D]

With a a ton of defense being played, and some overburdened referee's, this year is shaping up to be a rather "painful" year for our robots. So I thought it might help to have a place where we can all share our pain together . So feel free to post pics of the battle damage your robots have suffered this season.

Here's ours: these are our lift cylinders after one of our elimination matches (pics stolen shamelessly from one of my fellow mentors). We actually had a third cylinder damaged earlier in the regional, but I didn't get any pictures of that one.

We just finished playing at the Palmetto Regional.

We had 3D printed CIM mounts that were completely destroyed during one of our last practice matches, we spent the whole night 3D printing another set.

Also we went through about 4 encoders.

James from 95 posted some pretty impressive ones in his 95 at work thread.

Our team, also a CIR, destroyed out pickup... about 4 times.

Those pictures confirm the concerns I've had since kickoff with the extensions being 20" and the field being ripe for harsh defense.

Also, long cylinder rods outside the bumper zone are just asking to be damaged. The lever are is just too long.

Actually, those cylinders are entirely within our bumper zone. But we will be adding some additional protection for them at Wisconsin.

I think my team may plan to add foam spikes to scare away defense for our robot.

Here's a couple views of the FEDS' robot after a non-penalized frame perimeter infringement.





The shield did what it was designed to do. It protected the LEDs, the camera, and the radio (the camera and LEDs are aimed up and to the right). We would have liked to put the radio somewhere else but we didn't have the room.

This was a bumper mount that had been ripped and the bolt holding it on was stripped through the frame. This happened from inside the frame contact in QF 1.1 and was not penalized and resulted in us being disabled.


This was the replacement for a flap that was bent and snapped. That happened because of inside the frame contact that was not penalized and resulted in us not being able to pick up a ball at the end of the match.


This was a battery tray. the bent part snapped and broke after a high speed hit in QF 1.2. Did not affect anything for that match, but it still was a hard hit.

We had some complications with our shooter at Palmetto.
Turns out, the 1x1 versaframe couldn't handle the force of our hard stop and over time began to crack. Eventually, our shooter basically just broke in half. Thankfully it happened during testing in the pits rather than during a match, but it was not fun to have to replace the entire thing.

Just to be clear this is because of a catapult hard stop right? We are using the versa frame as well but not for the same application.

Folks, the 1" x 1" Versa Frame is only .04" thick. It's a really bad pick for serious structural applications.

Do I want to know how you found this out? Or are you just saying this because of the fact its .04 thick?

[Joel Glidden]

Just saying this based on the thin xsec. We didn't use any Versa Frame.

It's hard to pinpoint what exactly caused the system to fail, but it was likely a combination of the hard stop, the amount of force we were bringing the catapult down with, and a human error where we left the shooter clipped to the frame and ran it, putting loads of stress on the entire system. (interestingly, that misfire sheared our gears first). We were using the versaframe profile shooter on our practice bot and it seemed to be holding up fine, but now I'm questioning when that one will fail, if it's not about to already.
