Didn't they stop minting those earlier this year?

I've always wanted to know how dense and Andy Baker was... Now we can use it as a standard unit of measure :D. For example, Aluminum is 4.44 Andy Bakers.

On a slightly less silly note, OP, don't forget that, while we don't have weight limits in FTC physics is a harsh mistress. The more your robot weighs the more energy it takes to accelerate it. Additionally, this year you have to lift/be lifted by your partner.

Because it's radioactive

Only a little bit.

Tungsten and it's alloys are the densest one can get without paying precious metal prices or being radioactive, and being readily available (yay McMaster!)

Tungsten from McMaster can be had for 0.0026kg/USD

Yeah, but the darn things just won't go away. I think they are breeding like wire coat hangers or something.

No, single socks get turned into hangers by the dryer.

Getting a Little more serious, one of the densest materials for the buck is something scrap that is laying around.

Oh, come on... it's the weekend. It's time to be wacky! How about a teaspoonful of Neutron Star?

Now technically, that might not pass tech, but if you somehow mange to get a teasponfull of neutron star and keep it from destroying the entire planet... well I'm not going to argue whether or not you're allowed to have it on your robot.
