Re: Behaviour Of Single Solenoid Pneu. When Robot Disabled Legal ?
Yup...

So, if you have a pneumatic claw powered with a single solenoid, and you are disabled for any reason (i.e. a short communications drop-out, or undervoltage), you risk dropping your tube.

The only thing we've put on single solenoids are our mini-bot deployment latches which one released, don't matter if they return in the disabled state.

Despite the cost of needing 2 solenoid outputs to control them, double solenoids are your friend for the exact reasons you mentioned.

Also they are nice at maintaining the states between power-ups and power-downs.
