Deletion of Bump and Go toys

Comment: This mechanism enables automata to cope with obstacles so that they spin their wheels and then charge off in another direction.  A nice analogy, eh?  The details can be found in ''https://books.google.co.uk/books?id=Ah7g3rIKa8oC Tin Toys'' which explains how it works and that it is also known as the "Mystery Action" or "push-and-go".  As such vintage toys are quite collectable, there are plenty more works of this kind and so there's good scope for improvement per our policy , "''If editing can improve the page, this should be done rather than deleting the page.''"
