It's like when storm hits your house, there could be loss of signal but the house itself would still be fine. Similar thing happening herr where the robot is housing the snail. Robot is fine but snail signal is cut off due to the impact/can be established again.
Really... what a "nice" way to collapse the suspension bridge.
and if you're talking if I'm being sarcastic about it, then yes.
BUT, didn't they say that the ancient giant robot was nearly indestructible?
