The Author

The author, who is within spitting distance of retirement, learned his trade in the Royal Electrical and Mechanical Engineers, acquiring degrees and other stuff along the way, and has taught computing and microelectronics for some eighteen years at a further education college in middle England.

The Web Site

It should be admitted that these pages came about initially because the author was looking for an excuse to create a web site. The original idea was to present a fully worked project, with a detailed account of the building, the problems and their solutions, program design, program listings, etc, on the grounds that this might be of interest to others wishing to use the Picaxe system for their own projects. And so it might. Unfortunately, it might also have been of rather too much interest to school or college students undertaking similar projects, not least our own, so the temptation to publish a complete worked solution has been resisted.


The heart of this project is the Picaxe system from Revolution Education, who supply a whole range of parts and robot-oriented stuff.

Revolution has some Picaxe-specific pages which the author has found particularly useful. As well as the full range of Picaxe chips, project boards, etc, there is a comprehensive set of well produced data sheets covering all of the hardware, interfacing techniques and a programming language reference. These are an invaluable resource for anyone new to the system, and are still referred to by the author after several years. Like the Picaxe software, they are available for free download.

When we first had to teach control systems to non-engineering courses we relied on equipment and software from Economatics. They are still in business.

The components used for our reflective IR sensors are very common and could be sourced from almost any supplier of electronic components. The author has found ESR Electronics to be helpful, efficient and reasonably priced.
