Futuristic robots’ head could be designed with Orange, perhaps (6,5)
I believe the answer is:
citrus fruit
'orange perhaps' is the definition.
(orange is a kind of citrus fruit)
'futuristic robots' head could be' is the wordplay.
'head' indicates taking the first letters.
'could be' indicates anagramming the letters.
The first letter of 'robots' is 'r'.
'futuristic'+'r'='futuristicr'
'futuristicr' is an anagram of 'CITRUS FRUIT'.
'designed with' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Another definition for citrus fruit that I've seen is " eg Lime".)
