By the way, there are 5 states, all switches off, and each of the 4 switches. (That does not count the combinations if more than one switch were triggered at the same time). Thus a binary solution would take three inputs, just one less than the (...) (22 years ago, 16-Dec-03, to lugnet.robotics)

For a pure Lego solution, you could try rigging up something with a rotation sensor that would have the sensor point in the direction of the collision. Suppose the rotation sensor was mounted with it's input shaft pointing up vertically - with a (...) (22 years ago, 16-Dec-03, to lugnet.robotics)
