Automaton Building Video: How to Make Automata
From the site:
Making automata is hard. It requires a wide range of construction skills and an understanding of certain mechanical and engineering principles...The first half of the tape is divided into the following sections: Levers, Cranks, Linkages, Cams, Shafts & Bearings, Ratchets, Gearing and Drives...The second part concentrates on some of the ways the mechanisms can be put together to make automata.

Note: Those in the USA will want the NTSC version.
Here is a book that is also very good: Automata and Mechanical Toys.
