pic: Davis Bot Left Disabled

[Grant Cox]

Holy cow... as a driver, I'm not sure I want to see a video of that taking place *shudders*

Dont let it bother you too much though, skimming over rule G.6.984 is a common mistake that many teams make. Good luck on it next season

thanks

He was responding to a post about blast points and Sand People--the movie is Star Wars: A New Hope (also known as Episode IV).

I am not sure I want to see video of that match--it'll probably be more brutal than the regional eliminations I watched on Saturday!

That's the 2nd out-of-robot battery experience there was at davis! WOW!
to bad I missed that match!

[Darkswordsmith]

yeah, that game was just brutal. That robot got shreded completely, one of my teammates was crying in the stands. Surprisingly, no yellow card was given in that game i think.
Anyways, Davis' defense was crazy. We had to change the gearbox b/c it was damaged somehow from all those pushing...

Team 1560 has learned their lesson concerning acrylic XD

The panelling had already developed fractures over the course of SVR and earlier Davis qual matches which was bridged with aluminum. When the Harker bot (1072) hit us the panelling literally exploded.

Luckily most of the acrylic was cosmetic panelling, save the back panel which did hold the battery down. All the moving parts of the bot were still completely functional after the round. Harker gave us a piece of Lexon which we subsequently used to re-cover our electronics and we went on pick the number 7 alliance at Davis.

Oh, and we won that match too

[Jeremiah Johnson]

WOW. Yeah, can't say I like the way you've got your electronics covered, even with the side panels. An arm could easily accidentally reach down in there and detroyed everything.

If that picture isnt the greatest ad for using bumpers I dont know what is...

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

Ouch

That scene was so bad that I didn't even see it happen, I looked down for just a moment to write down some scouting notes and when I look back up, there's a mess on the field.

And that's our robot in the background, we ended up getting picked by them for eliminations.

[danshaffer]

i saw a few of these too. please, guys, build a real battery mount, preferably welded into your drivetrain.

I was watching that. That basically was the defense scene at Davis. It was intense. I believe just about everyone without bumpers had something like this (but not to that extreme) happen to them.

Davis was insane-like-a-fish!

[Koko Ed]

That robot looks about in as much bad shape as Greg's battlebot did.


And that robot was designed to slice through anything in it's path (literally. I found video of it doing just that on Youtube). What robot did that to that poor little robot?

[billbo911]

I have pictures oh this from the opposite angle. We were on deck when this happened. I'll try to post them later.
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.

We used some acrylic on one side of our mast in 2005 until we got lexan ready. Davis rolls around, and a team was particularly obnoxious in defending us in a couple of rounds (until we started lifting them by way of a tetra, then let them escape--but I digress). One round, they went up our (1/4"+ lexan) defensive wedges and hit the acrylic. The acrylic broke and we switched to lexan as soon as we could. Acrylic isn't a good idea if there's any chance it'll get hit with even moderate force. I don't think we've used acrylic since.

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. I’m making unbreakable bumpers for national.
