These robots are suitable for leaving outside (though their bodies are made of metal so they’ll rust. However the road lamp used in the body of this one is 70 years old and it still looks fine!). These lamps come in different colours so it’ll be dependent on what I can source at the time as to what you’ll get. The one in the picture is sold but I’ll endeavour to build your robot as close as I can to what you see. The lights on the eyes are solar powered and operate via the infrared detector that’s his nose.
