Hi John, some answers to your questions... 1) I don't know of any lego clubs in London - I live west of London and am not aware of any in the area. (maybe we should start one!) 2) I found this web site (URL) excellent for learning VB for Mindstorms (...) (25 years ago, 14-Dec-00, to lugnet.robotics)

(...) Thanks for that explanation, everything is much clearer now. I suppose it is to do with the line perpendicular to the vehicle coinciding with the centre point of the turning circle; with all wheel equal steering, it will intersect the middle (...) (25 years ago, 14-Dec-00, to lugnet.robotics)

(...) If you are parallel and very close to an obstacle, like a curb or a wall, you can't get away from it with all-wheel steering. As soon as you turn the wheel to get the front away from the wall, the back of the vehicle will smash into it. This (...) (25 years ago, 14-Dec-00, to lugnet.robotics)

You might want to look for information on "QuadraSteer". That's a Delphi Saginaw product (my company) that will be coming out on full size trucks in the near future. It adds rear wheel steering to the truck. The wheels are in phase (both turn the (...) (25 years ago, 14-Dec-00, to lugnet.robotics)

(...) I thought in the same direction. For driving straight you don't need a light sensor (but for accurate turning) It must work with two touchsensors that were touched from an arm placed on the "detector-wheel". So you are able to detect to which (...) (25 years ago, 14-Dec-00, to lugnet.robotics)
