It is the 1980s. Home computing is taking off and maybe there would be robots in each home by the end of the decade.
In this zeitgeist, The Goodies open their sole series for ITV with Robot.
The economic situation of the 1980s means that they have to downsize. It is bye bye to Bill and going on the picket line means up yours mate.
When Graeme builds a baby robot. Bill returns as a Swedish au pair named Helga . Somehow the other two does not notice.
Helga does not like the robot and tries to abandon it without success. Later the robot grows up to be a randy teenager.
The move to ITV was not a success for The Goodies. It was shown at an earlier time but parts of it would had been suitable for a more mature audience. A line up of Swedish lovelies, spanking and a robot wanting sex.
You can sense why the its family audience would have found it a bit too odd.
