Blasphemy! Everyone knows Mountain Dew is roboteer fuel.

We're 15 lbs under. We must be wayyyyy lacking in functionality....

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

I'ts actually carbonated prune juice.

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

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.

Re: 2 batteries
 

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.
