There are other places besides McMaster that sell constant-force springs in larger load capacities. Lee Spring is one source.

If you choose to go a stored-energy route, be VERY CAREFUL, especially with constant force springs. They are sharp and can easily snap back and cut off a finger, poke out an eye or worse. Gas shocks can be safer a lot of the time if they have damping to limit their speed. Regardless of the method, any stored energy solution with enough force to lift a robot off the floor will be dangerous, just due to the energy and forces involved.
