To my thinking there are two approaches to this, really two levels of difficulty, - Make it deterministic, in that if a switch is bumped invert your current trajectory axis, if going forward then reverse, if going R then go L. - Make it more (...) (22 years ago, 3-Dec-03, to lugnet.robotics)

(...) Oh I wish I had some of those touch sensors! One person from rtlToronto has a set and there is much envy from me to him. Right now I'm using lamp bricks, which isn't that great, really, but does work :) Thanks for the heads-up! Dave K (...) (22 years ago, 3-Dec-03, to lugnet.robotics)

(...) You should watch my three dogs hunt. If all you've ever seen is a single dog hunt then you know nothing of how dogs actually hunt.
