The Bedford Express 1023 crash- in GIF form!
 

During the first match of 1023 in Detroit they crashed, from the third floor. Watching it hurt my soul so much i had to make a GIF out of it.


Enjoy! :p

interesting fact!
in revers it looks like the most innovative climb so far.

How much Damage and of what Magnitude?

Well it wasn't fun.. and I don't plan on dropping our robot again. We had some pretty extensive damage, but we were only out for a two matches.

Our hopper and dumper arm and basket were smashed, the shooter tray was bent pretty bad, the uprights that hold our dumper welds broke, the shafts to hold the dumper bent, the fingers on the claw sheered off, as said before the sidecar shorted, and all the pwms completely melted, and an internal climbing component bent as well.

Ha! That is great! Thanks! :)

That's awesome.

Any idea why you fell?

We fell because our top latches slide off of the powder coated pyramid, and our bottom safety latches were disengaged. On our practice pyramid back home our top latches hold on just fine and we would remove our bottom locks for easy removal. But since we slide off, we have to keep the bottom locks engaged to hold us up.

That and, due to the playing field being less sturdy than we planned for, we took a less fatal fall in a practice match early in the day. What you see there is our 2nd 3rd tier fall of the day. The first landed us on corner bumpers which saved us greatly. We did have some damage that was later discovered which affected the later fall. Also, as Brandon mentioned, the powder coating made the poles much slippery than our practice field. A number of small factors all added up to that fall. Hopefully we will have them all resolved for our next event.

Not gonna lie, that was terrifying to watch. When it started smoking after it hit the ground, everyone on my team thought that the battery had ruptured. You guys really bounced back well though. Sorry that you didn't get to show off your awesome 50 point trick, but amazing work all the same, and best of luck in your next event!

You know...the reverse fall GIF is a little too fast for me to tell...but I think that if that had happened it would have been a valid climb...hmm...I bet someone could build a mechanism to do that...can you say ultimate climb?

Re: The Bedford Express 1023 crash- in GIF form!
 

I stand by my prediction that at globals there will be at least one alliance that is just 3 30 point climbers with solid autons. You won't beat everyone, but that's a nice chunk of points!

Re: The Bedford Express 1023 crash- in GIF form!
 

I would watch that alliance.

Have any teams tried doing two thirty point climbs at once? Obviously 30 point climbers are rare as it is, and getting two of them together for anything would be even rarer, but I'm curious as to what changes when more than one robot ascends at the same time.

Re: The Bedford Express 1023 crash- in GIF form!
 

The biggest gimp would be that you could really only feasibly dump with one of the bots (try dumping too many, and there will be overflow). As for the difficulties of multi-climbing, I'd say the biggest one is making sure that they don't hit each other trying to get to their respective corners

Closest we came to it after our fall.
BX 1023 Saturday Detroit

You guys did very well!!! :)

Well, to me it looked like one of the pwms came out of its motor controller, and its ground pin came in contact with 12v somewhere. Probably the power to the motor controller itself. You can tell because the ground pin was blackened, the entire length of the single wire was melted, and the motor controller survived.

So, that's a lot of current going through that small wire, and through the ground of the sidecar. Neither of which are designed for it. The wire responded by heating up a ton and melting through the insulation. Since the pwms were in a bundle, it ended up destroying the entire bundle.

In the end, only one of them looked like the culprit (since only one wire had been burned in its entirety). Although I gathered that the sidecar was dislodged and had smashed into the chassis, I don't think that was the real cause.

Buuuut I'm not on the team and I didn't get a look at the damaged sidecar. This is just what I figure from what I saw of the damage to the wire bundle.


And theeeen there was the second time you almost fell... If your rear bumper hadn't landed on the second level, it definitely would have fallen. It looked like only one of the grapple hooks was holding you, and neither of the ratcheting pieces.

I hope you get everything sorted out before your next competition. I was very impressed with your design. :D

Thankee

And I know. That was the closest anyone got in the qualifying matches to stopping 469. Well played! I'm assuming your next competition will be the Bedford district?

You mean the third time? (We fell in a practice match first) We dealt with residual problems for both days. We didn't even catch all of the affects of the original fall in practice &/or the 2nd fall, until we were tearing it apart after we were knocked out, to take off damaged parts. Part of our undercarriage got bent to where we didn't see it, but it prohibited the rack from fitting between it.

This caused a lot of problems along the way, and depending which fall it happened in, could have caused the others. It also prevented us from getting the 50 pointer on our succesful climb and dump because we couldn't get our tail up out of the 20 zone. Which makes me think it was our original fall that damaged it.. because, one of the things that triggered our second fall (the one in gif form) was we saw our tail was down, and tried to pull it up.
If you watch our original video, you will see it sit still for a long time, then movement, then fall. That was us trying to pull the tail up, then it sits still,but the weight shifted enough with the powdercoating making things slippery, that we fell... Sorry about the horrible grammar, but it is late and my mind is tired. :) I will try to upload the practice match fall when I can get it off my camera.

Thanks for sharing that video. I haven't gone back through all of ours yet. We REALLY got lucky on this one. And that is why we decided not to 30 point climb the last match. We were only going to go 20 points and shoot more, but we got lodged under the pyramid.

Looking forward to trying again though!! :)

it was a little too fast for me too, but looking at the normal direction, you can tell it was legal since the basicly slided down the pole. funny thing is one of my team mates offerd a climb similiar to this, he offered us to use pistons to push the ground and basically jump to the third step.

I was looking for this to show a few of our new students the reverse GIF but it seems to have been take down. One of my students decided to remake it.
