I am looking for the author / title of a short illustrated story about a robot (humanoid form) that crash-landed on planet earth and a boy finds the wreck. He climbs into it and goes up to the head and meets with the alien kid. Shortly after, the "mother" robot finds and rescues the stranded robot and the story ends.
The robot's control station is the "head".
I remember the cover having a yellow border and depicting in a grey tones a forest. In the centre of the cover there is a golden humanoid robot wreck, mainly the "face" is shown.
The book should be of the mid-80s and no more that 25-75 pages with a couple of illustrations and in english language.
