Crib, too, became mechanical (7)

Ross

I believe the answer is:

robotic

'mechanical' is the definition.
(I've seen this before)

'crib too became' is the wordplay.
'became' is an anagram indicator (I've seen 'becoming' mean this).
'crib'+'too'='cribtoo'
'cribtoo' with letters rearranged gives 'ROBOTIC'.

(Other definitions for robotic that I've seen before include "Unthinking, like a machine" , "Mechanical; unemotional" , "Automaton-like" , "Of or using automatons" , "Stiff, unemotional" .)

I've seen this clue in The Mirror.
