Erik,
From Section 1
MINIBOT – an autonomous vehicle designed and built to perform specific tasks when competing in the 2011 competition LogoMotion. The MINIBOT must obviously follow a design approach intended to play the 2011 FRC END GAME and must be compliant with all MINIBOT rules defined in Section 3.4.14.

And from Section 1.5
The match ends with robots deploying minibots, small electro-mechanical assemblies that are independent of the host robot, onto vertical poles.

I read those two references as not tethered. The Q&A will be the only place to get an official answer on this question.
