From 50's or early 60's. Possibly called Out of this world, but memory may be totally confused. It was a different story each week. One was called (I think) Little lost robot. A man is working on something mechanical and asks the robot to pass him a spanner and the robot gets it wrong. The man gets angry and tells him to get lost, so the robot mixes with the other robots which are indistinguishable but do not have the intelligence of the lost robot. They have to find the lost robot as it has the special abilities so could be dangerous. So they set up a situation where it looks as if a woman is going to be injured by some machinery. The robot comes out of the group of robots to save the woman and is "killed" by a hidden electrified tripwire. Another story had a radio ham (possibly called Joe) who contacts an alien spacecraft which is in trouble (the inhabitants are just like us, including american accents). They are very wary but he convinces them to trust him. He talks them down to where he is located. Their panicking voices are next heard on the radio claiming he has tricked them, they are in a swamp and they can see a monster serpent outside their window. They can't believe that Joe has done this to them. Joe rushes out into the rainy night to see what's happened and tramps into a puddle crushing a tiny spherical spacecraft underfoot without even noticing. Most of the stories had this sort of twisted irony to them and, as a young kid, I always felt an emotional impact after watching. Be very grateful if any can give me any info on this.
