Wow, that was allot of smoke.

Do you know which team that was and what caused it?

Re: anyother robots smoke up?
 

it was 1189, and i never found out, but i heard that it was a lose screw or something, ud have to ask them

:eek: That's impressive! What burned? Last year we had a bad soldeir job on a pwm short, It fused several other pwm cables together and melted our wire wrap but it was nothing like that. I'm going with a short (possibly a motor of victor burning).

Re: anyother robots smoke up?
 

There was another bad smoker at GLR along with 1189. I don't remember who it was, but they had the fire extinguisher ready.. and it was red. Both smokers had lovely smells...

That was the most magic smoke in awhile.

One of the teams at Florida regional started to smoke in the middle of the field. I am not exactly sure which team it was. They burnt a fp.

Re: anyother robots smoke up?
 

holy cow! that's like a smokestack! are they renaming their robot?

Re: anyother robots smoke up?
 

I remeber that, but I dont know who it was. I know 47 blew out a drill motor, or so it appeared from all of the magic smoke.

While working on the GTS, another member wanted to test the shooter programing so we simply "unplugged" the pwms to the drive system. We carelessly left them there and didnt move them so when the programmer turned on the robot....poof...lots of magic smoke form the pwm cable that contacted the 12v power to the victor. It comepletey melted the pwm cable...luckily we had some of the Y-pwm cables laying around.

Re: anyother robots smoke up?
 

which motor are you referring to? we didn't have drill motors this year

Arefin - The team that had the release of magic smoke at UCF was us in Q18. We burnt out two FETS on one of our speed controllers for the drivetrain while pushing two other robots. The ref onsite said he knew the smell and said it had to be the fp, but on return to the pits, I confirmed that it wasn't the FP, I had rewired everything that morning and knew I hadn't connected it that match. It wasn't much magic smoke from the speed controller, but we hit disable before further damage/smoke could occur. Although after this I'm slightly uneasy about the 40amp breakers reliably popping before the speed controller fries...

(As a side note, we had a lot of bad electonic luck in UCF.... We turned on the robot after uncrating it and all of the 5 spikes were dead. They were working perfectly when we shipped...... IFI rep personally tested them and seemed just as confused as us that all 5 were dead and all the other electronics were fine.)

Last year at nats our battery lit on fire...we never figured out how/why. We think someone may have dropped it at one point...

burned all of the electrical tape, and melted the insulation off about 6 inches of the 6awg leads. Thank god for the brave ref with good reflexes who grabbed the battery and, I kid you not, threw it a good twenty feet.

Thankfully this happened about 2.5 seconds after the match was over.

Re: anyother robots smoke up?
 

Sorry, I called the DeWalt motor a drill motor. But I remeber the bottom motor of your shooter puffing out smoke.

Re: anyother robots smoke up?
 

If memory serves me correctly, I seem to remember team 59 (RamTech) smoking a bit after getting on the ramp... no idea what match it was though.

Re: anyother robots smoke up?
 

The worse thing that happened to us this year was a frayed wire in contact with our robot. The entire thing had a current going through it and when a judge touched it he got shocked. Oh well.

I coached that match against them. Sadly, after they reset the field and removed 1189, Huskie forgot to completely reset their robot (thanks to the backup battery) and ended up going nowhere in autonomous instead of scoring all those balls. Not that we did much, as we were still dealing with a lot of other difficulties.

At any rate, I managed to talk with some guys from 1189 on saturday, and related our hard-luck story of losing a match cause an opposing robot went up in smoke. And then discovered that it was them. Apparently some battery leads got twisted up with some PWMs in their turret. Then they either got pinched or otherwise exposed and shorted. And thus full 12V to ground with no breaker. I was honestly wondering how you could possibly make that much smoke without tripping a breaker. I suppose it's good to know that you in fact can't.
