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... R |

Re: Methods of adding ballast to underweight robots
Turns out newer (past mid 1980's) pennies are actually 97.5 percent zinc and only have a 2.5 percent copper coating. Who knew?
I think either the pennies or just scrap bolts we have lying around will work. I'll have to take a look at our junk bins later this week. -vivek |
