There was discussion of one company that made switches with analog values
that could be mixed, but they were apparently either expensive or hard to
find (at least there was some difficulty).
But simple resistor network, say a load resistor to ground and each switch
with a different series resistor from positive reference voltage, could feed
an a/d channel. It sounds like what was packaged in that particular system,
but could be done with inexpensive resistors and external wiring. Then
analog voltage ranges determine the binary combinations of the 4 switches.
Does this make any sense? (Of course one could use 4 separate inputs, but
that might tax available resources).

| 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 (...) (21 years ago, 16-Dec-03, to lugnet.robotics)

| 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 (...) (21 years ago, 16-Dec-03, to lugnet.robotics)
