Don't know if anyone's interested but these past few day's I've made real progress with my robot. I seem to work better in the cold rather than the heat of the summer - heat seems to bother me. Because I'm making a large robot everything is heavier so it is more awkward e.g. motor power. I have to say I'm impressed with the Alaskan robot www.neogentronyx.com. Now that is a robot and a half.
Thanks also for certifying me (in the robot sense not my insanity!)
