This qualifies as a candidate, I think - I was watching these last night - check out the autonomous bumper to bumper hit:

I asked the team about it after the match when they were picking up the pieces. Let's just say, there is a really good reason you use polycarbonate and not acrylic on robots.

our first grabber was acrylic, as was our nice pot mount. to demonstrate why acrylic shouldn't be used on robots, our build captain threw the grabber on our shop floor. it shattered, and we moved to a lexan pot mount and a lexan + aluminum grabber.

Yeah I was worrying about our platforms getting tore in pieces because we don’t have side bumpers. But those carbon fiber and fiber glass honeycomb platforms proved to be stronger than I thought. We have a small dent on the fiber glass side and that’s it. Our bumpers got ripped off of our robot a couple of times though. Then again, they were attached to our robot by a few wood screws.:rolleyes: I’m making unbreakable bumpers for national.

Be wary... this is FIRST... If you say it's unbreakable, someone will find a way to abuse and break it on the field.

But anyway, I was amazed at all the defensively flimsy robots this year. It was clear from the existence of a single scoring area that the defense would be disturbingly heavy, and so I was surprised when I saw so many casterbots and bots without bumpers.

Yeah but this is not battlebots, so I think as long as I bolt them down well, they should be fine.

Review the rules with regard to the bolts that are supposed to be
used for bumper attachment. A specific bolt size is specified.
You now know the reason for that. The inspectors at Atlanta
have promised to be more picky.

I seriously would like to see the video of this match... I want to see exactly how this happened.

Does anyone know if any yellow cards were given as a result?

They mentioned that no yellow cards were given out.

Wow. We ALMOST, I mean, like, were this close <--> to getting a yellow card, and that was for playing 'high speed defense'... I guess the ref really makes a difference.

Here's a little more of an action shot.


Obviously several bots were involved, and I think it was just a matter of combined forces on the exposed (and kinda brittle) outer plates. I'm not really sure why the battery popped out, but I know things didn't get rough enough to merit a yellow flag.

Ahh, Second bot I've seen with a fallen battery at Davis. I think it happened to 1031 as well.

Haha that's not just a fallen battery. I know it's prolly been asked before but is there a video of this somewhere?

As far as I know, 3 bot's lost bats. I have pictures of ours (1147), 1031 and 1560 all with a bat on the floor. I'd post them here but I can not attach pics in this thread.
