Perhaps the light sensor could be placed at the end of a vertical arm that
swings in a cone pattern. This would prevent the twisting of connectors.

| Actually, My thoughts were of mounting it geared in such a way that the light sensor traces a circular path without ever actually, itself, rotating. Imagine mounting to some kind of rotating assembly and then mounting that to the end of an arm. As (...) (25 years ago, 16-Nov-99, to lugnet.robotics)
