To rob, perhaps, is inhuman (5)

I believe the answer is:

robot

I'm a little stuck... Click here to teach me more about this clue!

'is inhuman' is the definition.
I can't judge whether this defines the answer.

'to rob perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'to'+'rob'='torob'
'torob' anagrammed gives 'ROBOT'.

Can you help me to learn more?

(Other definitions for robot that I've seen before include "Mechanical man" , "Unpaid worker" , "Android, possibly" , "Mechanical worker" , "Automated machine" .)
