Is he inhumanly able to rob? (5)

Ross

I believe the answer is:

robot

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

'is he inhumanly able' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.

'to rob?' is the wordplay.
'to rob' can be anagrammed to 'ROBOT'.
Though, I'm unsure how this is indicated.

Can you help me to learn more?

(Other definitions for robot that I've seen before include "Man-made man - man-made machine" , "Android, possibly" , "Automation" , "Automatic worker?" , "Programmable machine" .)

I've seen this clue in the Evening Standard.
