Programming the last thing a robot does...

There is already a ruling in the Q&A section. I think it was posted today.

When the clock is 0:00 the period is over. There are no more points to be scored, even if the ball is in the middle of a hurdle., it will not count. There are no residual point scoring actions after the clock runs out.

If your team representative(s) haven't read the Q&A section on FIRST Forums, just do it. A lot of questions posted here have already been answered there by the GDC. They have the answers and make the final rulings.

EDIT: Sorry about the confusing answer to the original Question. From past experience, only the KEYANG motors or a worm gear cannot be driven backwards by hand. These definitely require tethering after the match if they are extended.

if using pnuematics, just put in a pressure release valve in a strategic location.
