As I'm sure you know—but in case others haven't considered this—weight does not include buoyancy. Our conventional methods for measuring weight don't account for that source of error, but with most robots it's negligible.
If you bring an inflatable robot to inspection, I wouldn't be surprised if the inspectors make you calculate the weight of the contents of the gas bag, and incorporate it into your official weight.

1 By implication, the gas bag can't be a pneumatic part (arguable, depending on the robot's configuration), and the gas is a part (and by further implication, so should be the air in your pneumatics). To avoid those inconvenient complications, instead use a large, lightweight chamber full of vacuum.
