The conveyor belt material, I think, was donated by the company of one of our parents. He works for a cardboard, I mean corrugated box manufacturer :D
With our 110 pound robot, TWO (2) wheel drive, we were able to push a 300+ pound man, sitting on a metal chair across the carpeting :ahh: Can you say massive traction, I knew you could :)
Our bot will turn on a dime and give $.09 change ;)

that is fantastic...

...what is your "shell" made of...can you tell us some more how it works?

Re: pic: 1501 Final Robot - see you at BoilerMaker!
 

The entire body and arms are .040" aluminum. The rear trunk lid is .090". There are two 1/8" steel plates that our uprights are bolted to. The uprights themselves are also .040" aluminum. There are NO bolts holding any of it together, only rivets.
When you bend aluminum around a form or into c-channels you increase the rigidity of the aluminum. You than rivet the pieces to each other or to sheets to get the maximum strength. I'm just the CAD mentor so I don't know the whole theory of monocoque assembly. I do know that the arm can withstand tremendous twisting or bending forces.
Hope this helps.

It's like a cross between a bird, a jet engine, and a toaster from the 1960's.

Well done. That is a sweet robot.

Re: pic: 1501 Final Robot - see you at BoilerMaker!
 

The real thing I am not understanding is for that to work does it have to be always latched on to the frame? How do you get to things like electronics and to the battery? Do you have to drill out all those rivets and put new ones in?

Re: pic: 1501 Final Robot - see you at BoilerMaker!
 

If you look at the front of the robot you will see a piece of polycarbonate. This covers our electronics, compressor and air tanks.
In the center, between the two uprights, you will see our air bleeder and 12v on/off switch.
At the back you will see two black knobs. You remove the knobs and you can open our trunk :D That's where our battery is. We have plenty of trunk space to add weight if we need to :rolleyes:
The lower chassis is made up of former, bulkheads and sheeting with rivets holding it all together.

A few words came to mind when I saw that picture:
"Wow"
"Beautiful"
"Elegant"
"Simple"

It looks like you guys had the same attention to detail and functionality that I aim for when designing software interfaces. Incredible! That's a fantastic robot, and I hope I get the chance to see it in person!

You are correct.
The bird is a Hawk. We prey on little tetras :ahh:
The jet engine look was taken from the SR-71. We are strong.
And if you look close enough you will see two slots for bread. We are still trying to debug the auto-butterer :D

The final rivet count was...........1794.5
We didn't win any awards at the Boilermaker :(

We did win 2 awards one from the cybearcats for the best button award and we won the professional grade award!!!

Re: pic: 1501 Final Robot - see you at BoilerMaker!
 

Yes that is true, although we didn't win any during the award ceramonies. The professional grade award is an official FIRST award voted on by all the other teams attending the event. Which we are glad that the teams attending the event thought our team and robot was "professional grade".

However its not about awards and winning, its about learning and having fun, and thats exactly what we did!!! :D

See you all at IRI, and if not there i will see the rest of you next year at the Boilermaker Regional.
