Photos of Team 2883's robot

[Rusty shaklferd]

These are a few photos of our robot for this seasons match. The robot is designed to drive over bumps and has a kicker for shooting the soccer balls. Enjoy

Holy lots of brackets and bolts batman!

How much does it weigh? Looks very clean.

[Chris is me]

Cool.

Have you guys climbed a bump with your robot? Does it make it over? How well? At angles?

[Rusty shaklferd]

Thank you , and weighs probably about 55-60 lbs. right now.

The utilization of the HDPE wheels is an interesting new development for FIRST this year. We never had these wheels before last year... at least they weren't provided and therefore never used. How's she drive?

Yes it gets over well, we are waiting at the moment for our track system to come in, then it will manuver very well over with it.

It rides like a cadillac and stings like a bemur

Also the reason for all the bolts is to limit the amount of welds this year for our robot, as of now we have no welds on the robot.

I hate to be the bearer of bad news, but this thing's frame would never pass inspection as it sits now. There are just so many things wrong with it. Did you ever see the terms FRAME PERIMETER and BUMPER PERIMETER in the rules? Or look at rule <R07> at all?

Plus as pictured you are getting a penalty for <G46>.

[Kage]

Thats a cool idea using only nuts and bolts...
My team has had our frame welded every year for as long as I can remember...and then we have skeletons of welded frames from even before that lol

I can see the advantages:
no cracked welds
perfectly straight members
extra rigitity...

our robot is all crooked :|
because there were so many small parts to weld together this year...
but it still drives straight as an arrow =D

I question how this is definitively violating <R07>. They can easily attach bumpers to it in the appropriate zone, and its unclear whether that frame is 28x38 and thus the bolts etc are or are not clear of the 28x38 dimension.

I concur on <G46>.

My $0.02:

Nuts and bolts are HEAVY. Welds are a much more weight efficient joinery method.

I disagree with the advantages you listed. Welded frames are virtually always lighter and stiffer than fastened versions. Good welds won't crack. Good jigging and fit-up can virtually eliminate warping.

Okay, well this robot is not finished yet so we don't have a cover, we know of these rules and our robot will not break these rules when finished. Also somone commented about the nuts and bolts, yes we know they are going to weigh more then welds but, it is something we wanted to go with with this year to avoid issues and it is working well as of now.

Those bolts would be sticking in well past the wood backing of the bumper and into the noodle zone. Also, the left and right sides are not flush with the frame.

we will be cutting the bolts down so that won't be an issue
