Weight Issues

I believe it. We ran our QuardaMax G2 off a power supply with just the Chias and it drew like 3 amps no load and then we ran it with both the Chias and the drills and it ran at like 2 amps no load. And then squeeze a tube of grease in there and you'll harldy be pulling any current at all j/k Anyway, I'm sure the more motors - less current relationship depends on the motors involved and is only true up until a point.

For a low weight robot, the cool thing about that is that you can pile on all the extra junk you want later (lights, horns, hampster wheels, random blocks of lead, etc.) because you'll have the extra weight to do it.

Our rookie year, our robot was like 80 lbs and we added a 20 lb bumper. Solid iron bar. Worked very well. All we had was a simple drill motor drivetrain and one arm. We still view it as a very effective robot that was well designed and played the game well.

I would say that you should look at your weights again. I think that your numbers sounds low for accomplishing all those goals. But not knowing what systems you use, I have no idea.

I think thatits important to use your weight limit as much as possible for good systems. If you are still under, make huge push bars. If you ever play us, you will need them. J/K

if you realy intend on going to the center to stop other robots from hanging you ned to be able to push them off because a robot with a climbing mechanism will way at least 90-100lbs so you need to be able to counter that.
Last year, in our rookie year, we were at 81lbs, and last year pushing was a big thing.. which we failed at... so this year we're aiming at 100 pounds.. nice round figure.. should be good

to the original post?- all that matters is that your under the 130lbs. like some 1 said before... y stop at 100?

Its gonna go up the stairs no matter what the weight is (lets be practical here ). Just be sure that your center of gravity is low. That way when you do climb up the stairs the robot wont tip over.

Just a FYI, our robot is 90 lbs without an arm and it gets up the stair just fine.

Also when you use metal you frame will probably be .2 times heavier so no matter what you do it will be heavier.
