Let's Make Robots!

2009 FIRST FRC Robot, Team 2197


Ok this year we had to design a robot that could successfully collect these “moon rocks” and then deposit them in the trailer of the opposite alliance.

Sounds pretty simple but!!!

It has to weigh less then 120lbs, fit in a 28”x38”x60” box, use only specified motors and pneumatics (we used no pneumatics this year), use only a certain battery, and a hole list of other rules (three ring binder full). But still you have a lot of freedom to design whatever you want. Oh and we only had six weeks and a budget that is set by FIRST. It’s all to keep things equal though so it’s cool.

Andrew Early (remember that name) and I basically designed the thing during lunch and after school for a week straight. It got very intense at times because there are so many different ways to accomplish the task given to us. Upon finalizing the designs we started to scavenge for parts and assemble things.

About five weeks later we had it built, programmed, crated and shipped to Ohio for our first reginal where we placed 6th place out of 59 teams.

I could write an entire book on the many long nights we spent building this, and all the different ideas that came to mind in the process but to spare the life of my keyboard and your focus I will leave it at this for now. As anyone who has ever built a robot before knows, I love to be asked questions about my creation so please feel free to ask them. Like I said I know I left out a lot of details but I can’t possibly answer every question someone might have, so please just ask in a kind manner and I will be glad to answer anything for you. I had a ton of photos on fliker but apparently my account got switched or something and I lost them all, ill figure something out soon. If your dispirit to see more, again just ask and ill e-mail some to you.       

 

 

Though we had many a few Autodesk Inventor drawings we never used them for construction. Basically just all off the top of our heads! If any drawing of any sort helped us the most it would be this 2 minute MS Paint drawing I wiped up to convey our idea to our adviserCIMG0110.jpg

Instead of using a bunch of pulleys and stuff I had the brilliant idea of just putting the intake rollers at a 90^deg angle and linking them with a gear bot. Only problem is we didn’t have a gearbox like that… But a company who gave us a lot of materials (E-Pak Machinery) had two bevel gears laying around and some thick plastic that machines like a god. Lo and behold this is what we ended up with. Though there isn’t that gear on the shaft anymore, it was replaced with a single motor direct drive much more eficent. I don’t know if I have a picture of that… Had so much fun making this!!!

Thanks!

And yes we have sponsors that donate parts, material, and most importantly money. I’ll try to post some of our sponsors and load more pictures in a little bit. Sorry it’s just I have some stuff I have got to get done for school and it might take a while. Unless anyone here happens to have or now of a good high power DC motor speed controller, schematic? I’m talking 24v 70-80Amp??? Because I need to control the speed and direction of two wheel chair motors, anyway I’ll be on the web trying to dig up some information.

What a great robot and congrats!

Are you funded for this project? $6000 doesn't seems like a garage project. lol. You should upload more pic or link to your pictures. Thanks for sharing your work.

No :(
oh, well did you watch the webcast? it was odd that 3 teams in the finals were from michigan
I watched it... It was awesome.  BTW are you in 2016 Project Mayhem?  My team is 75, your Chesapeake alliance!

2866 project mayhem and yep, i was the driver throughout the competition.

 

The kid Nate from Johnson and Johnson, he is a soph in college is an awesome person, he got our bot running.

 

The captain on our team knows nothing about robots, which is whyu it looked like what it did, and i dont go to the school so i couldnt do anything about that, but thanks to your whole team mate!

right i meant 2866...

yeah i know nate, and i'm glad our team could help

i hope you guys do well next year, i cant hardly wait to see next year's game!

 

 

and woops i missed your reply just above...  cool we found eachother...  what r the odds?

yea that is pretty cool, so you were at chesapeake? what is your name? maybe i actually did meet u, ever come to our pit, or were u at urs?

and i cant wait to see what next years game is as well.

team 75 was cheering for us alot though :D and congratz on the award i think it was judges at chesapaeake?

 

btw sry for jacking ur thread mate XD

I was at chesapeake, but not in the pits (But at the end I remember high-5ing a 2866 member...).  I was doing some strategy work up in the stands.  But I'm Eric by the way.

And it was Engineering Inspiration award.  But we didn't get a thing in Atlanta... although we were almost picked as an alliance.  They accidentally called team 79, not 75.  They later apologized...but we might have won...

But whatever, there's always next year.  I'll probably be in the pits next time at Chesapeake... I might see you there.

 

Good luck with your butlerbot thing btw.

 

P.S. Sorry Justin for chatting up your post... :)
