Let's See Your Robot's Battle Scars

[AustinH]

Thankfully, no visible damage after PNW Glacier Peak. We do have a large quantity of paint from other robots well inside our frame perimeter. Gonna have to do some touch up work this week.

706 Superior battle damage some of it any way didn't get pics of the worst

You can see that piece of square tubing is supposed to be parallel to that ruler and is bent in about 2 inches as well as having the end 3 inches bent down about an inch with the rivets ripped out and the belting torn off.
We also had our ball centering device which is a piece of .125 by 3 inch piece of aluminum and is well within our frame perimeter bent at almost 90 degrees over the last 3 inches. No pic because we were in finals and had no time to waste.
Was a lot of fun though
also had metal sheered off as seen in this pic.



Build em strong this year!!!!

A lot of these failures are not terribly surprising.

Our contribution:


This failure was not unexpected, so we'd brought along the drive pods from our practice robot as spares since they were designed to be easily replaced. We lost two rollers during qualification matches, discovered it before elimination matches started and replaced the pod after our first quarterfinal match. We broke another two rollers on a different wheel pod during the elimination rounds, but played with the broken wheel.

Our worst problem of the week was that we threw a keystock in one of our intermediary axles that caused the wheel on the transmission shaft to throw tire treads constantly. It took us riveting and ziptying the heck out of the tread to rectify the situation. And we also completely shattered a window motor into pieces, but it wasn't working anyway so no one really cared.

Additionally, we had our sponsorship lamination ripped in 2 places, we broke a chain, and some of our surgical tubing came undone. We kinda got the crap beat out of us/did some of the beating ourselves.
For once though, nothing electrical or structural!!!

We didn't have anything break, but we have alot of scratches and scrapes on our intake. Our side panels also kept getting bent in because of all the defense. Some other robots fared alot worse in Oregon though.

We broke our pickup arm and several of our Pneumatic Pistons from defense this year. Here is a video of Semi-Final Match 1-2 where our pickup completely breaks off after our last piston breaks. We had to emergency stop our robot to prevent any more damage. Even though we did break our pickup for our robot, we still had a lot of fun and had a great laugh from it. Can't wait till this weekend to have our new more robust pickup attached.

We also broke several hex bearings and chain that was also attached to our pickup.

you see the red brace (second pic) the one on the other side of the bot has a large dent in it.

3634 had a bit of a rough time. We ripped apart 3 window motors that were powering our "el toro" style intake. After the second one broke, we decided not to put the arms down anymore, then when the third one broke (still inside the frame perimeter) we took them off entirely. We also lost our battery in several matches where the velcro that was holding it on ripped at the bolt attaching it to the frame. Shout out to 1699 for helping us rebuild our battery box! We had no further battery issues after that.

This was damage sustained during the Central Illinois regional.

We didn't get much damage at GKC other than scratching up some of our powder coat, and some black scrapes on our collection roller.

What was this gear used for, and what conditions caused it to fail?

A team next door to us at the Sacramento Regional pulled out 2 of those "toothless" gears from their drive train.

2 of 1388's wheels suffered this damage at the Sacramento Regional during the first elimination match. Andymark is actually contacting us for information

[April_robo]

My team (3548) while playing defense got our sister team's (1188) intake roller stuck in our chain between the chain and the sprocket. Ask anyone at the Howell district and they will tell you it was brutal. I had to take the chain off on the field. I do not have pictures but I'm sure someone on chief Delphi does

It was on our drive. Our center wheel is directly driven by the output shaft of our gearbox. This gear was cantilevered and was 1.5” from the nearest bearing. We replaced it with a steel gear which broke too. We ran only in low gear, which was also cantilevered, but worked well. We’re going to try switching to 20 degree pressure angle gears that are .500 wide and supporting the shaft on both sides of the gear.
