Well pretty much as predicted no work on the book has happened this week. The Nao has eaten up all my time left over from writing a research grant application, reviewing conference papers and marking assignments.
I've got to grips with the Nao's programming language which is quite easy to use and have been playing with its sensors. Voice recognition is a bit hit and miss but the two video cameras on it work very well. For example it can now turn around until it sees a know mark and then walk towards that point - small steps but important ones. The basic idea is to build up a collection of basic routines, like turn around or walk ahead and then combine these into more complex behaviours.
