The picture above is a robot dog made by Philips, somewhere around 1958 I guess. It was taken from the book ‘PRACTICAL ROBOT CIRCUITS: ELECTRONIC SENSORY ORGANS AND NERVE SYSTEMS’ published by A.H. Bruinsma and the ‘Philips Technical Library’ in 1960. The book gives a nice insight of the progressive research that was done in those days. Besides some nice images of electronic dogs and fold-out charts there is also a nice picture of a huge electronic Noughts & Crossesmachine. If somebody happens to run in to this dog… please let me know.
