Main Question or Discussion Point
I am trying to make a floating sentry bot ; though, my plan was to use Helium or with a mixture of Ammonia. I want to find the minimum amount of gas in a balloon require to reach the max height the object should float. I know the buoyancy force is Density * Volmin * g : where the maximum potential energy of gravity is W*Hmax. I'm not sure if I am correct, but I would have to equate the Eg = Wgas correct?
