Re: Robot Weight

We're shooting for 103, but it will actually weigh either 119.9 or 120.0 depending on whether the code has more 0s or 1s in it

(and the fact that you actually know what your robot weighs now puts you about 4 weeks ahead of where we were our rookie year)

Re: Robot Weight

I don't know yet, but I suspect that the ideal weight is around 100 pounds. This will be a reasonable trade off between mass and acceleration.

Re: Robot Weight

Right now ours still weighs zero pounds, because we haven't even started building it. But we're figuring the chassis and drivetrain to be right around 50 lbs. Then there's the electronics, pneumatics, and all that stuff on top that will magically make the ball score billions of points. That will add up to a lot of weight.

Re: Robot Weight

we are hoping for 100 Lbs. but since our robot wighes 85 we are kind scared because we only have a driveable robot, with no scoring stucture.

We are just now starting on finished parts and finished frame. We had a prototype frame running but we never weighed it.

What is your frame made out of and what is your drive train? I estimate our base and drive train will only be around 35-45 lbs.

We used the kitbot frame, very light and strong and we biuld up from there. Try mounting your electronics onto a piece of 1/8 inch LEXAN, this will be much lighter than the wood.

LEXAN is great. Strong and light. You can pick it up at most metal supply stores or Lowes and Hone Depot.

You might want to think about modifying your frame to make it lighter.
