Robo Damage after this years competition

This year had plenty of defense. Post a pic of how damaged your robot got from the 2019 season. You can also add a fun description of how it happened.

This year, our bumpers weren’t exactly the best, but they passed inspection. This was the state of our bumpers after our last competition. We also saw that our outer plate was slightly caved in from ramming. Lol

I don’t have a picture, but our base was made of welded+bracketed 1x2 1/8 in aluminum tubing. The brackets that we used had 4 rivets in them. One of the corners on our drive train had a weld on the top and inside and a bracket on the bottom. From repeated HAB level 2 starts, pretty much a whole season of defense, and a couple falls from level 3, the corner broke of our base snapped in competition.

This is what happened after playing defense against 868 during quarterfinals at Indiana State. They accidentally ripped out our bag motor and tore off the top part of our cable chain with their cargo intake. We got a yellow card for it. :frowning:

Edit:
I don’t want to sound like I’m throwing shade, just thought it would be fun to add.

At the end of our first regional, our robot was pretty destroyed - plates bent, bolts bent, rivets pulling out, belts stripped, everything was held together by zipties by the time we were eliminated in semis. Although we chose to play defense, and continued to play defense even after it was clear that our superstructure was getting wrecked, so we have no one but ourselves to blame :slight_smile:

This photo was taken between when we were eliminated and when we rebagged. We removed one of the stages of our elevator so that we could fix and robustify it at home and bring it back as our withholding allowance, and ended up bagging our subsystems in two different bags. This picture shows our intake arm and elevator gearbox resting on the drivetrain.

We did manage to put it back together in time for our matches at our second regional, which was its own kind of victory.

The bendy bolt in question was a Grade 8 1/4"-20 bolt, so we’re naturally quite surprised by how much it bent by. The other is a piston rod which was bent in the same process- these both came out of our hatch handler mechanism when our driver went a hair too fast into the wall.

Contrary to all of this carnage and what felt like a bare knuckle brawl on the field, our robot this year actually has far less physical damage than at the end of the season in most recent years (2016-present). Our Stronghold robot had the most damage, followed by Power Up, then Deep Space, and then finally Steamworks.

It certainly felt more brutal, but I don’t think the amount of damage is actually that much greater than usual.

Even though we used thin wall tube on our elevator and all of our chassis, we had no issues with it (other than a gouge from where the carriage got pulled out of its track by jamming it into the rocket - oops). This includes many falls while attempting to climb, all they did was break a 3d printed mount piece (we had about a dozen spares since it was an easy fix). The most damaging part of this game was definitely the bumper cut out, which mangled 4 of our corner shields (thankfully not the swerve motors!) before we replaced them.

So we subscribed to the religion of climb by yeet. After an issue with lining up, we decided to not be very committed to the religion. But it’s okay because we didnt want this bolt to come out anyways.

(note all the holes with no rivets in them)


(bracket is supposed to be upright and bent at 90°)


(aluminum scabbed over broken polycarbonate tube, one of 3x times this happened)

Most of this damage is related to defense, mostly having it played on us, sometimes us playing it.

This sheetmetal is what our climber/ball intake arm is attached to. Much bracing was added after this

This wheel was on the end of our jack leg that came down for our climb. As the season progressed, the gearbox which powered the jack loosened just because regular wear and the jack leg began to slip during a the matches. This lead to the wheel just sitting on the ground and the carpet became a belt sander. The wheel didn’t however hinder any of our climbs, we just found the whole process to be smoother after we changed the wheel. Now we just pid our jack up at the beginning of the match and make sure it stays there until we’re ready to climb.

This was not from defense, it was just a drop of the control while in the human player station at the practice field. That’s the top beam of our arm. Very unforgiving, yet our great pit crew managed to mount a backup.
