That shouldn't have worked. Assuming that you have two Clippard AVT-32-16 tanks with 16 in
3 each at 120 psi, and four 24 in stroke, 2 in bore Bimba Cylinders on board (realistically, that's way more than you'd expect, even neglecting the tubing), at 120 psi and 60 psi respectively, the amount of air on board is only about 0.06 lb.* If you went from 120.1 down to 119.9 ("*just* under 120"), there's a leftover 0.14 lb to be accounted for. More likely, you just got lucky with the error in the scale.
And here's a question to which I don't really want to know the answer: do you need to weigh the robot with or without its compressed air?
*This assumes an air temperature of 21°C; in reality, the air is probably hotter than this due to being mechanically compressed. And that lowers the density even more.
