Re: Methods of adding ballast to underweight robots
I think you could use pennies ... They are just about 25% less dense than lead so that's not bad. Better than steel which is something like 30% less than steel
Steel bolts are cheap though...put them or pennies in a PVC pipe...

tungsten is what you really want... but expensive...twice as dense as copper..
pretty cool stuff...
