Let's See Your Robot's Battle Scars

[cglrcng]

Robot is just fine, but 3rd Q-Match before the picking begins Saturday morning....FRC Driver station up loaded on the Laptop LCD and ready to play, robot already placed on the field and the drivers station panel is placed on the shelf, our drivers are ready to battle.....A cable from the drivers station gets caught on top of a jeans belt loop (my son's), while walking away heading back to get behind the line and wham.....The whole panel flops off the shelf upside down and all the weight lands on the edge of the display lid top edge. The display plastics of that Dell 1502 Laptop is fine, but the LCD is cracked (shattered), internally, the screen is rainbowed pretty colors in the shattered corner and just white everywhere else (they cannot see a thing on the screen), and they went on and played the match w/ it like that, and won. (The FMS is absolutely great!)

Luckily that added Dell accelerometer program came on that unit, and the HD must have parked momentarily during the fall, as the HD checked out just fine.....They borrowed a classmate from FIRST AZ, and a monitor to see by, while they copied off the programming and loaded it up for the last 2 Q's and elimination rounds.

Sure enough both BU Laptops were left at the shop 3 hrs. away (First time in years). New LCD will arrive tomorrow, $59.00 and they are back in business again.
---------------------------------------------------
Things could be much worse for sure after looking at ALL the pics in this thread...Ouch on the laptop above...Snipped...."Of course, the laptop screen decided that this would be a great time to go belly up." Decided to? OK..Lol.

Something tells me that laptop screen didn't have any choice whatsoever, in that situation at all! That is much worse damage, and looks like it was run over by the loaded robot cart too!...Though if hooked up to an external monitor and that drive is still OK (Disk Check and a defrag w/ Defraggler (Piriform.com), use the Health Monitor bad sector check), all the rest looks quite fixable. Doesn't sound like the unit was on, so the HD should be absolutely fine.

E-Bay is your friend for new & used puter parts. Our drive was powered up and spinning when it flopped to the carpeted floor from the shelf. Luckily the G-Force had to be just enough to park it first before the hit. (Not a bad sector found).

And that Gummed Up Wheel and the bearing...Whoa, took some real force to break that bearing like that. I see a lot of added "character" in the pics, as they call it in NASCAR.

Our drivers station overhung our robot cart and got banged by a trophy case in the hall en route to a match. Of course, the laptop screen decided that this would be a great time to go belly up. Luckily, we had our classmate in the pit.

Ian, what make/model is that laptop? You check the hard drive, I'll locate the parts for you. Upper Clamshell and LCD are fairly cheap.

So, we got a little bit of the field tape in the drive-belt....

never again will I doubt the power of a cim motor

We knew that we would be missing our driver for the first few matches of Friday so on the practice day we were training a backup driver (who may or may not have been me, I cannot say either way ) anyway lets just say that a robot with an extended intake travelling at 15 fps plus the low goal makes for some interestingly shaped parts - linked picture of a bar on the linkage that drives our intake.

At the Peachtree regional 4468 has had 2 main things happen to us. First we picked up about 10 ft of field tape into our belts during auto one match. Enough tape was sucked up to completely derail our belt. The second thing that happened was we snapped a bumper in half not the short way but long ways (2ft long) sadly I don't have a picture of it though.

Long Island didnt see too much bad damage from what I could tell. The extent of our damages were a tread broke off a wheel and we didnt realize until the next day, one belt hub cracked in 20 different places and bent a bolt holding it after a particularly hard hit and we slightly bent our harvest wheel but it fixed itself over the course of the day.

Overall me and the rest of the pit crew had a very relaxing weekend of just reloading the air

Week 5 Livonia Finals were very physical.

[JagCode]

During the WAAHS QF4.3, our robot got bashed, slammed, rammed, and even slashed. A mechanism from Bear Metal cut rope, elastic cord, and surgical tubing from the insides of our robot. Furthermore, CHUCK's bot bent in our intake from the front, and from the side, resulting in bent pistons and the near destruction of our intake roller and it's subsequent crossbar.

Horns of Havoc, one of our alliance partners had 3/6 of their 6" Hi-Grip wheels shattered due to CHUCK's excessively aggressive defense. Their intake too, was nigh destroyed due to bent pistons and broken joints. (Their intake, instead of lowering, does a scissor-like extension.)

We've got a big dent in the front of our AM14U, two PG188's with the output shafts sheared into two pieces, and a very bent hard-stop on our roller arm. I'll post pics later if I have the time.

That said, the gearbox failure was the fault of insufficient design (never considered the torque generated by the arm getting hit hard while it was being actuated down), and the frame dent didn't affect structural integrity and seems to be par-for-the-course (we're going to swap out that frame section and reinforce it with a steel bar for our next competition).

It's a very rough game, but not cripplingly-so. Worth noting that we were on the giving side of the defense after our arm went out of commission, not the receiving; but I don't think we caused any significant damage to other robots. We certainly tried to push rather than ram, and to avoid extended appendages.

In the last Friday match at Livonia, we got the gaffer's tape stuck in our 8 wheel, #25 chain drivetrain. While struggling to get loose, we broke two chains, threw four others, and our belly-pan electrical board fell off. Thankfully, we were able to fix it before opening ceremonies on Saturday, but the damage was very scary looking.

We, too, had a dent in the front of our AM14U (self-inflicted because of our own aggressive defense play-style and an opening in the bumper for ball intake). To repair, it took a 2x4 and a hammer. We subsequently supported the middle front of the AM14U.

Agreed. If your 'bot is built well, and you keep your appendages in (as much as possible) you should not suffer too much damage (nothing that you cannot repair easily).

In our last match at QCR, the window motor operating our pickup forks got stripped, leaving the forks sticking out of the robot's general protection. Two walls, three robots, and one particularly fast ball later, and the damage was done. We are building more robust ones for the WEGL regional this week.
