There has been some talk of changing the schools micromouse competitions. I am in favour of a more flexible line-following class of competitions. While doing a bit of research, I found many examples of the kind of thing I had in mind. Given that these competitions are much more popular in South East Asia, I was not surprised to find that most of the information and examples were to be found in Japan. What I was surprised to find was just how well advanced the state of the art is over there.
