From Q&A:

A. We will not rule definitively on hypothetical scenarios in this forum as many factors may play into rulings in individual situations. Generally a Team will not be called for G11 (attempting to draw a foul) if they are, in the judgement of the Referee, attempting to play the game, however futilely. There is no exemption from penalties for ROBOTS which have become immobile or DISABLED.

It sounds to me like, should this happen, a robot should try to continuously move the "dead" robot from the secret passage....
