I love that frame.

Re: Team 935 as of 2-2-2008
 

Agreed...All that machining is so sweet. How much does it all weigh? I love the roller idea!!!

Re: Team 935 as of 2-2-2008
 

Absolutely love it!!

I see a made a good Fantasy FIRST pick :)

I loved Newton's bot last year. Combined with 1775 in Kansas City, it was a very deadly alliance. Excellent chassis.


Edit: When will you all be able to put some video for us to enjoy?

Re: Team 935 as of 2-2-2008
 

Thanks. When we weighed it we threw on our cable drums and our electronics parts and it weighed about 109 lbs, i think. I don't remember what it weighed without anything on it. I think it was somewhere around 100 lbs.

Re: Team 935 as of 2-2-2008
 

wow that bot weights that much!!! Where is it all at????

Re: Team 935 as of 2-2-2008
 

where do you guys plan on mounting your electronics? I dont see any place that is pretty good and covered to mount it.

Re: Team 935 as of 2-2-2008
 

well, the chassis weighs around 64 lbs and the elevator weighs around 36 lbs. We have a habit of building our chassis a bit heavier than many teams.

There will be a space right in the center of the chassis. That's probably where I'll end up mounting the electronics. We usually just mount them wherever we can fit them.

I don't really know, although I'm hoping by the end of the week. We're never usually that lucky though.

Re: Team 935 as of 2-2-2008
 

that is one cool bot
good job

Re: Team 935 as of 2-2-2008
 

I wouldn't think that frame would weight that much

Re: Team 935 as of 2-2-2008
 

Regarding the weight of the frame- it's aluminum extrusion, isn't it? Bolting the entire frame must add quite a bit of extra weight, and extrusion is at least twice as heavy than box tubing due to sheer mass. Are you guys going to be a pushing bot? Weight would help there. A robot pushing the weight limits isn't always bad. Sorry, pun not actually intended.

Re: Team 935 as of 2-2-2008
 

ah i didnt see the bolts, i thought it was all welded

Re: Team 935 as of 2-2-2008
 

The chassis is made out of 1/4 inch aluminum that is cut with a CNC machine. There are no welds, the entire robot is bolted together with 1/4 - 20's. I think that the weight that I said earlier was with the battery. I had to include the battery when I was trying to figure out the robot's CG so I probably forgot got to subtract it from the weight. We probably wont be a pushing bot, we just have a habit of building heavy robots.

Re: Team 935 as of 2-2-2008
 

ah, it's still a very nice frame.

Re: Team 935 as of 2-2-2008
 

Very nice! I hope you guys don't have any issues tipping when you put the ball up.

What's your drive speed?

Re: Team 935 as of 2-2-2008
 

I'll second craigs vote of watch your center of gravity but you've probably already got this all figured out.

looks awesome though

Re: Team 935 as of 2-2-2008
 

We've been worrying about tipping too. With the elevator fully extended we have calculated the CG to be right at the front set of CIM motors, which is about 12 inches back. Our velocity is somewhere around 11 ft/s. We just have to be careful not to come to a dead stop with the elevator fully extended.

Re: Team 935 as of 2-2-2008
 

the chassis looks really strong

great idea
