Blasphemy! Everyone knows Mountain Dew is roboteer fuel.

Add a couple of cases of Mt Dew (or Dr Pepper if you can stand that vile stuff - reminds me of cough medicine).

And if I remember correctly (and our scale is working properly), we're about 80 pounds with the battery and bumpers...

And Al, thanks for the idea of painting the lead. We're about to cut some lead ballast for our robot, and I was quite concerned about the inspectors deeming it a hazardous material unlike our anything goes mentor. Paint (hopefully not lead based!) sounds like an ideal solution.

Back in the days when we were adding lead ballast to our robots, we used to coat the lead brick with liquid plastic tool-dip from the hardware store. It makes a very nice, tough coating that completely traps any stray particles. It stands up to a reasonable amount of abuse, and if you need to later it is relatively easy to peel it off.

Okay, easiest way to add weight is to zip-tie boxes of bolts onto the robot. They even come conveniently with a handle...

On a second note... make sure you seal them tightly...

I agree, and it also adds a nice non slip surface.

We found some spray on rubber coating at OSH that seems to have done the trick quite nicely.
