another way to make multiple points of stop for pneumatics is to use many tiny stroke pistons. this is expensive and complicated but it is just as strong, can be much faster (instead of slowly filling 1 large piston you can slowly fill 2 small ones, tripling or doubling the speed depending...). the only issue is keeping stability constant, to do this i recommend a sliding arm action, and i haven't seen a design of that yet that doesn't compromise the integrity. a good part about pneumatics is that, for what i know, there is no limit to how many pistons that you can use, the only issue is how quickly it takes to charge them all. problem is that generally speaking pneumatics are much heavier, considering the pistons tanks compressor tubing and connections.
