How did you guys have enough time to do that? Don't you have a robot for this year to finish? I'm jealous...

*runs numbers for a theoretical 8cim drive*

Re: pic: Don't Let the Mentors Play!!!!
 

Heh... Reminds me of the summer after 2004. Me and 2 other members of the team took our 2003 robot home to reassemble it after having cannibalized parts for the 2004 robot. Then we rode it up and down the street in our neighborhood.

Also, we have a robotic cart powered by IFI equipment (I posted a picture of me on it at GTR 2008 a while back).

How fast does it go?

Re: pic: Don't Let the Mentors Play!!!!
 

Theoretically or Physically?

Re: pic: Don't Let the Mentors Play!!!!
 

We made a robot like that. It was just a chasis with a wooden chair on top for someone to ride on. A little too dangerous for the mentors. Never got to do it.:(

Re: pic: Don't Let the Mentors Play!!!!
 

Looks sick Mark. I want to build some cool stuff. May want to put a guard near those chains. Would really hurt if you got your pant leggings caught in there.

Re: pic: Don't Let the Mentors Play!!!!
 

Maybe I should get Richard to comment on this thread to tell how it feels to get something caught in chain.

Since the 4-DeWalt wonder of 2008, we've had a permanent guide on his hand as to the spacing of #25 chain...

I can't believe nobody looked at the CIMs and transmissions and thought "Hey those are mounted backwards!" Am I the only one who looks at the robots from an inspector's point of view?

Re: pic: Don't Let the Mentors Play!!!!
 

Al-no you're not.

There are also two IFI controllers and I think that battery is not to spec.:rolleyes:

Re: pic: Don't Let the Mentors Play!!!!
 

My monitor is dim and my eyes are old. I can't see the controllers or the battery. If it wasn't for spell check you couldn't even read what I am writing.

Re: pic: Don't Let the Mentors Play!!!!
 

In fact, I think the IFI controllers are being used as transmission gussets. I can think of better ways to save weight...

Re: pic: Don't Let the Mentors Play!!!!
 

That is a car battery, if using the regular batteries, they die, quick. Yes the CIMs are reverse mounted, I was too big and some students were too big to fit into it with them the other way, so we flipped them. Yes, those are OLD IFI controllers, with OLD sticks too. Does anyone remember PBASIC!!!???!!!??? Yes that is a pre-2003 controller! There are chain guards on it now, that was the first thing I put on before I took it out for initial testing with just to 4 CIM motors. I haven't gotten it out with all 8 CIM motors yet, but it was peppy with just 4 on it. I believe the way it's geared, it will theoretically go 106 mph and some change, but physically with 200+ pounds on it, no where near it. Not that it does take it some time to get off the line, but that was with 4 CIMs not 8!!! After the season when I have gotten it to run consistently I will put up a movie.

Me too - severe violation of FRAME PERIMETER. Not to mention those wires are entanglement hazards.

Re: pic: Don't Let the Mentors Play!!!!
 

Yes, but this picture was before it was totally finished. They are all strapped down with wire ties, and neatly out of the way. There is also now a big back on it, with an old BFL! Safety is a goal on this device!

Re: pic: Don't Let the Mentors Play!!!!
 

Yay BFL! *Points to our forklift-robot-cart-thing, complete with our 2003 BFL*

Re: pic: Don't Let the Mentors Play!!!!
 

Is it against the rules to mount them backwards?

Ex. flipping the side the motors go on the gearbox

Re: pic: Don't Let the Mentors Play!!!!
 

Hah that looks like our x-bot

it is just a basic chassis w/ motors and a chair bolted to it.

safe? no.

awesome? you betcha.

Re: pic: Don't Let the Mentors Play!!!!
 

Numbers,
I was just joking. When you look at the picture is appers to be a kitbot chassis with the motors to the outside which in normal competition would make the robot base really wide. But upon closer examination, there is suddenly eight CIM motors which is also way too much. Everybody is getting crazy this close to ship. Have some fun!

Re: pic: Don't Let the Mentors Play!!!!
 

Put some mecanum wheels on there then it'd be REALLY fun :ahh:

Re: pic: Don't Let the Mentors Play!!!!
 

soo jealous, if that robot goes missing it has nothing to do with team 706...

Re: pic: Don't Let the Mentors Play!!!!
 

Heh, alright. Rookie team, we've already had many people attempt to implement their ideas without reading the rules :o

Currently our motors are attached on the same side as the output sprocket for the gearbox.

Re: pic: Don't Let the Mentors Play!!!!
 

Are you sure about that? The next question is "Are the maximum dimensions of your robot still under the 28" x 38" requirement"? A common rookie slip up is to make the robot exactly 28" x 38" only to find that their tolerance is +/- 1/4" and the 1/4" lies outside the dimension specification. The First tolerance is 28" x 38" +0.0000". This is the tolerance used by inspectors.
