Blackbox,
From a playing standpoint (and an inspection standpoint), entanglement refers to anything on your robot that could become entangled with another robot or the playing field. This could be stray wiring, rope, twine, netting, or something flexible enough to get caught in another robot's mechanism(s) that would prevent either you or the other team from playing effectively in a match. The GDC is of course the final say on this but I am betting they won't be able to render a decision (those of us here either) simply on the statement of the question above. We all want you to play the entire match.
