I had been interested in electronics since I built my first radio when I was about 13 or 14 in the late 1970s and I'd learnt to program on a borrowed ZX80 a couple of years after that, but this was my first proper interfacing project. I was living in Wembley at the time, an impoverished student teacher and one of my tutors suggested a cheap robotics project might be interesting as a way into Logo and this was the result.
