fall over
 

yes.. we fall over..

We also fall over, but try to have some fun with it. We fell over once in qualifying matches and once in the semi-finals (not for long however, thanks 356!)

If you were at STL Regional you saw 525 bottom: "Help! I've fallen and I cant get up!"

We are planning to show the bottom to no one at nationals :D

heh, so do lots of other robots when they are on the ramp..we fall over, but not on accident, nor on the ramp

We can make robots fall over, does that count?

our robot is too short to fall over :)

No robot is too short to fall over.

Our robot tipped itself once in autonomous mode when our pnumkatic "wings" hit the side of the ramp at the same time we ran into cheezypoofs but normally we have no problem.

We have decided to make a video out of only robots tipping over after filming quite a few during the practice matches.

No robot is too small to be tipped over. At Sacramento we tipped over quite a few robots and ALMOST tipped ourselves even though we have such a low center of gravity.

Most robots get tipped over when they are pushing up the ramp against another robot. Let's say the back wheels are spinning counter-clockwise when your robot is pushing up the ramp. If your robot isn't going anywhere, the force of moving the wheels needs to go somewhere. Usually your wheels will just spin, but with the robot at such an angle the force will cause the robot to pivot clockwise around the back wheel and you will tip. You will tip even faster with a high center of gravity, but low robots will tip as well.

Basically, if your robot starts to tip, stop pushing and reverse directions!

Not to threadjack, but that was the most concise and accurate post I've seen on CD this season. Bravo.

our robot fell over like 10 times at sacramento... no non-cosmetic damage whatsoever :D

Hey! Team 612 played 8 QP matches(apposed to the 7 matches the other 61 teams @ VCU played before semi-finals), and we didn't once fall over =)

I'd like to think we were 'un-flipable' with 110 pounds, almost perfectly balanced around the robot(except for the 15 pound wedge)

Not to mention our ground clearence was ~1 inch with interior wheels(so we dont 'ride' up a robot =)




Other then that, I think most robots flipped =) Question is, can they get back up? =) Lol we can't, but we wern't designed to allow any room for 'flippage' =)

I only saw 1 team successfully do that, Grats to Sparky/Team 384 @ VCU Regional, too bad that's only a 1-way flip recovery arm =p

356 helped right 525 in the semi-finals, I believe, at St. Louis!

It was easily the hilight of the day!

Sparky tipped over durring a match against a box, but then the arm self-righted Spark and the match continued.

Sparkey was cool =)


Though I had to admit i was cheering when the judges said you all lost the VCU semi-final seed =p (we were your competators after all)..

But, fair is fair, you had more QP, and won fair and square =)


btw JosephM, take a look over at http://www.chiefdelphi.com/forums/sh...threadid=19089 I had a question for 384 =) Also, most our team liked Sparkey too =) but we had to ally with our alliance partner for last year :( I was chearing for ya though (when i wasnt fighting ya!)

Gabe answered all your questions Lee.

Thanks for the comments guys.

We flipped. Then we stripped. (the robot) now it wont fall. but i saw a little short robot drive up on abox and flip. it was so sad. =)

HAHAHAHAHAHAHa
 

Team 967 thought way ahead and can drive up side down. We even won an award for it!!!!

I saw the Visoneers robot fall over onto a box in front of fellow Rochesterians Grrr Robotics who tipped them back upright (by mistake no doubt since they were opposing them).
835 got knocked over once and I think 85 BOB pushed them back upright. It helps to haave good capable partners to help you out when you get into trouble.

Maybe they were just being extremely good sports. Nobody would fault Grrr for doing nothing or even making it harder for the Visioeers to get back up. It is entirely within the rules to do so.

But helping your opponent get back into the game is a very generous and sportsman-like thing to do. (assuming it was deliberate).

We Rochester teams like to stick together.:D

Plus Grrr are a bunch of good guys as well.

after that match we went and thanked grr for it and they said that they were moving the robot around because they couldn't see where it was and fliped us back randomly........we still thank them for it,

thanks again guys

Life is full of happy incidents.:)

I think my team might beat everyone! If this is something to be proud of. . . Lol.
We are modular, and both of our robots tipped. Not only that, but the BAHA BASHER Mod tipped a few, although others drove up and flipped themselves, NOT OUR FAULT!!

We went over twice. First time was in practise, we were headed up the ramp in auto when 16 came flying down, I mean, flying and over we went. the GI team later came and shoved us around by means of our wings. Anyway, they destroyed our poor left wing. I think they were going for our stacks, but we had to redo the wing.

The second time a qual match, a teammate was driving and tried to climb ontop of 45 after they went all king of the hill on us . . we were about halway up when we went over. The left wing had to be completely redone once more. By the end of the regional, it was held on by zipties and little bits of wood.

We only flipped one team, and that was their fault. We were preventing them from coming up the ramp, and their back wheels just kept goin as their front went up (i don't remember #).

Later their partner rammed them, shattering their light cover. At least we didn't do the damage, only the flipping.

OK, my favorite flip was at the VCU regionals.

1051's auton mode wasn't quite calibrated - I watched it swing a wide arc toward the ramp - too wide, so it hit the ramp with it's front right tire and flipped over all by itself. What was great is it repeated the move identically in the next match.

Good thing they got that figured out. Also, 1051, I really like the look of the bot and your wicked, toothed arm. I wanted to see you use that on some bins.

I don't really like when robots fall over... It kind of takes the fun out of the competition...

This is so funny because what the thread started about was if you fell over at the start like Beatty did last year. Not if you tipped cause all bots can tip/ be tipped. IF you where are New England you should know what I am talking about.

Mehh team 564 makes flipping over stylish. We were doing it way before any of your little robots knew what topheavy was. Not only that but we won the one match last year when we did and almost won a second one. It was so funny we fell into our scoring zone and the other team did not even know.

We flipped 651 on the ramp, YO-BOT the infamous box thrower and crowd pleaser. But they actually got back up. they used their arm to self right as well.

The bigger they are, the harder they fall:

falling over
 

We fell over twice at the New England Regional, but thanks to our arm driver we were able to right ourselves both times.

I believe there was one time you guys fell over sideways and were unable to right yourselves- you were stuck on your side and your arms' range of motion prevented you from nudging back on track.

We fall, we also flip but due to the nice arm we flip back over rather easily.

we've never flipped. I think that having interior wheels helps alot - most of the flipping i've seen happens when a robot rides itself up on-top of another robot. It is much less frequent that a team will ram another robot and flip it.

Yet to be flipped

yeah... but we are suppose to fall over.. our robot starts in a standing up position.. then falls onto its side.. thus making our bot 4 feet wide. :D

You can tip us but you can't knock us down.

We are over 4' tall and we have stayed up in every match. To see proof of this watch the regional finals. We even managed to drive on 704 and 118 without falling over. We had a couple close calls but were saved by our caster wheels and beveled front.

Good luck at Nats:)

lol Clark (696) almost flipped us in the semis at SoCal, even though we are like 10 inches tall with 2-3 inch ground clearance, not to mention we were on the same alliance. Our arm might have been able to self right, but luckily we didn't have to try :-)

just out of curiosity... who else out there besides 573 fell at the start of the match intentionally... and how'd it work out for you guys...

-lisa :)

Cyber Blue's robot is very top heavy and we have had to many close calls to remember. We've learned a few tricks at keeping the robot upright, but unfortunately we weren't so lucky at our second regional in Arizona. We fell over in the qualifying round but went on to win the match with little damage to the robot.

our arm in the down position acts as a perfect wheelie bar so we can't be flipped over from the front or back...
