In rereading this thread and thinking always about safe operation, the precharged and locked cylinder makes me wonder what happens when the vent plug valve is opened. (I do a lot of "what if" analysis. Sorry, but that is what I do) So these are my questions as I consider operation...
1. Is there ever a chance that the locking cylinder could release the piston as system pressure is vented?
2. Is there a mechanical lock that prevents uncontrolled movement when the robot is powered down?
3. Is the robot carried off the field with the cylinder under pressure and what happens if the robot is accidentally dropped or shocked?
4. When the cylinder moves, is the movement exposed to the outside of the robot?
5. Knowing that the PVC storage tanks have failed in the past (from external forces), are they being used as intended with rigid fittings to a moving cylinder?

Did I miss anything?
