Lifting after power is cut

[StashZabriski]

Is it possible (rules wise) to mechanically lift the robots after power is cut?

My team is talking about starting the action in the last couple seconds of the match and allow the robot to do its thing to lift an alliance's robot 4" or even 12" into the air after the final buzzer.

I keep wanting to say it's against the spirit of FIRST and as a veteran ref I wouldn't allow it to consistantly happen, the only problem is that I can't find a rule to back what my gut is telling me.

If there was under an inch to lift after power, that's one thing, but the team is talking about lifting a significant distance after the match because things are normally scored when the field comes to rest (trying to work around the rules).

Easiest way to show this is a counterweight like in the FLL challenge this year (not feasable, but there's other ways). Release the counterweight with 2seconds left in the game and in 4-5seconds AFTER the power is cut, the robot would end up at its final height of what ever the team wants.

Any thoughts would be appreciated so I can pass this on to the team.
