Re: Methods of adding ballast to underweight robots

If you can find a gunshop that will loan you a bag of Tungsten shot, that is about as dense a material as you'll commonly find. Costs about $30./lb. Lead shot is much cheaper. An old bicycle inner tube partially filled with shot or old wheel weights and tied up like link sausage should be pretty easy to strap on there somewhere.
