Can you place boulders in the outerworks?

[3072BBots]

You can't feed boulders to a shooter bot. You have to completely cross their defense with contact with "your" boulder or you will receive a foul.

G39 ROBOTS are prohibited from launching BOULDERS unless they are in contact with the opponent’s TOWER or carpet in the opponent’s COURTYARD, and not in contact with any other carpet.

G40 A ROBOT may not cause a BOULDER to move from the NEUTRAL ZONE into the opponent’s COURTYARD unless:
A. the ROBOT contacts the BOULDER within OUTER WORKS, and
B. the ROBOT completes its CROSSING (i.e. doesn’t completely back out of the OUTER WORKS into the NEUTRAL ZONE)
