Mistakes

[M. Gildner]

Test driving our robot and it hit a pillar and severely bent the forks in front. After this we added a new rule for our team: Don't let David Killoran drive the robot!!![

[Enigma's puzzle]

we had a couple of small metal shavings fall into the victor, it didnt move very far when we put the robot on the field.
The programing team also forgot to put an absoute value into the mecanum programing, That robot only went left, and later we decided to name it lefty

Always shave down the metal AWAY from the RC!!! And then we learned that its not always the programmers fault...

Also, 2 days ago at Cage Match in Indianapolis. Make sure you use a insulated tool when working on batteries. It turns out that the negative side which was taped up had been pulled out slightly, and i did not see the revealed wire. So the all metal multitool that i was using made contact with both polarities and sparks flew. Then i pulled the tool away from the battery. Only then did i realize how hot the tool had become. Now it has burn marks on the tool i was holding, and i could not feel my fingers while driving in the elimination round. In order to remind me, i think i may make shirts that say "Samir, don't electrocute yourself" with a pic of a body getting hit by a lightning bolt inside one of those red circles with a slash down the middle.

Our lead electronics head last year was playing around with one of the circuit boards and somehow bridged two wires together and like the wires went crazy red and then melted like half of the board. No really bad injuries thank goodness, just a little cut on the finger.

When tools make nice noises, they work great. However, anyone who has worked in a machine shop knows that as soon as you let the angry noises out of tooling, they automagically stop working.

So you can see where this is leading...

I hit a fixturing bolt with a 1/2" carbide end mill at 8000 rpm in a CNC machine once, which made a lot of angry noises as it exploded into thousands of pieces of shrapnel. It was not fun.

Same thing, except not minor in any way. 2.5" carbide insert facemill spinning at 6,000 RPM straight down into the top of my vise at 1,000 inches/min.

I remember seeing that happen, I think we were even with you guys as an alliance once.

But oh man mistakes were do I begin, so many, so many.

Well one would have to be while I was showing others some of the basic electrical parts on a dummi board I had turned power on to demonstrate some stuff. Well I went to point something and when I went to point at something, I touched a PWM cable. Well that cable happened to be connected to the RC and the other end, well was plugged into nowhere. Well the metal leads on that touched the power source on a victor and there was a nice mushroom cloud of blue smoke.

Lesson learned. CHECK FOR Loose or unplugged wires BEFORE turning the robot ON!!!


That is only one out of many, I could go on forever but I won't, and I am sure others could do the same.

I, for one, am perfect and therefore make no mistakes. Unless you count all the times that I completely screw up.

Seriously though, In 'Aim high' my team was a rookie. I was in charge of rules and had only read the "important" parts. Apparently, the parts you make the bot out of was an important part. Oops. We used illegal motors and had to completely redesign our robot at the event. Still had fun, but I learned to at least skim through the whole manual...if you don't have to actually read it.
