The Most Successful Logo Turtle in Educational Robotics

In 1983 a teacher and aspiring journalist Anth Ginn introduced me to the ideas of Seymour Papert and Turtle Robots.  I loved it and set out to design my first educational robot.  I was a mechanical engineer working on different contracts so I knew large numbers of talented people.  I soon got a team together: Dave Ewins to do the electronics, Graham Carpenter for the software and Peter Pavlitski who organised the production.  The result was the Valiant Turtle.  The British Design Council included it their book the Best of British Design and I soon found out that education was how I wanted to spend my working life.  We sold the last Turtle in about 2010 (we could not get the parts to make them anymore).  A few days ago I came across Simon’s blog.  He kindly let me add it to our records.  I hope you find it interesting – Dave Catlin.

Historical Record of the Turtle Robot Development

In 1969 Professor Mike Paterson was young English Computer Scientist visiting Bolt Beranek and Newman.  Seymour Papert gave him the task of writing a specification for the first educational robot, which was initially referred to as the LOGO ambulatory executor and more prosaically as the Bug.  Later named the Turtle in reference to Grey Walter’s early work with Tortoise Robots.  This is the first of two documents by Mike relating to the development of Turtle Educational Robots.  This document was provided by Wally Feurzeig of BBN Technologies who led the project that invented Logo.
