60s or 70s picture book search

[Grimble69]

DH spoke of a book he enjoyed reading as a boy. I'm pretty sure it was a picture book for young children but it might have been a child's book with pictures.
The story was about a robot who made brown cars in a factory but got bored doing this so went and did his own thing, possibly making cars in different colours.
I've tried searching through Google and asking his family for the book title but without any joy. I'm really sorry I have so little to go on but if any of you remember this book and remember the title and or author that would be great. Perhaps I'll be able to buy him a second hand copy.

This site might help as it has suggestions on how to search for a book

Thanks, I tried this site.

I don't really have enough to go on for searches. I was hoping that someone on here might remember the book.
I don't think there were as many children's books around in the 70s so more of us would have read the same books.

Ah, I presume you've tried UTNE and GoodReads too then?

Just tried Goodreads, not had much success it's a difficult website for me to navigate. I can't even seem to generate a form to start the search.
Thanks for your help.

Is it Robbie the robot?

No, not Robbie, thank you anyway. The robot might have been called Mekanic or similar.

Thanks, no not Robbie the robot. A possible name for the robot is Mechanic or Mekanik or similar.

Update, it was Clanky the Mechanical Boy and MIL still has it.
It'll be heading our way very soon.
