The battery weighs 13.45 lbs (uncharged, without 6# wire), and the compressor weighs 4.73 lbs. I'm going to assume you're using extrusion due to the weight of the frame (36 lbs :eek: ).

awesome chasis
 

Total drivetrain assembly weighs around 27 pounds with motors and gear assemblies plus drive platform.

our complete chassis weighs 9 pounds. thats without a tranny or anything. but the chassis itsself that holds the robot is 9 pounds

Is ours to heavy
 

our chassis with motors wheels and such weighs 88lbs. is that to heavy? We still plan to mount a robotic arm and the controllers. what would you recommend to do, we have already put many holes in the frame to reduce weight?

Re: Is ours to heavy
 

Haha, speed holes, the way of FIRST...What are you using as a material for the chassis? Got any pics we can see to help ya with reccomendations as to what we could do to cut that down?


...and again, "My bot meets Weight requiremnts on mercury"...

we put our chassis,all motors, actuators,valves,electrical components and everything we think we need to use plus a big 4000 page book on a scale and it wieghed 85 pounds. id say were pretty good as far as wieght. :)

team 61.. We are up to 120 pounds but we are just about finished and we plain on using all 10 pounds that is left we always push to the max.... We have not worked really late nights and i can't believe that we are almost done.... :D I look forward to see some other teams post pictures of there robots we have a few posted already..

First 5 pictures are ours

The weight
 

I heard this team...somewhere in bloody ole Connecticut has a chassi which weighs about 8.5lbs. That's bloody good. Good luck to the chaps in Connecticut competiting with these cats.

If your frame is under 10 pounds and made of legal material, it is not strong enough.

Greg

It is quite possible for a frame to weigh less than 10 pounds, if for example, it were made of wood and the robot was only 10 inches tall.

The Weight
 

These cats tell me its made of somesort of metal. I've felt it, it certainly feels strong enough. Sorry gents, can't divuldge anymore than that.

make your correction sport,

"the world demand for computers might be as high as five."

-Thomas Watson, head of IBM, 1940.

Watson

A quick question is it legal to build out of fiber glass? Because that stuff is lighter than aluminum and close to steel in terms of strength and wieght.

Perhaps you mean that fiberglass' strength to weight ratio is comparable to that of steel?

I just hope that the teams making 10 lb frames out of wood realize the forces involved in head on, full speed crashes (which autonomous mode almost guarantees).

Just some thoughts :)

Greg

Oh, i'll fix my profile - im suprised no one pointed that out to be before now :P

Greg-
I love that quote from Watson. You must want to work for IBM in the near future. Good luck to you chap.
