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 (...) (21 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 (...) (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)

You could attach 2 touch sensors to each port and take a look at the raw values when different combinations of the sensors are pressed. ----- Original Message ----- From: "Øyvind Steinnes" <phoenix@online.no> To: <lego-robotics@crynwr.com> Sent: (...) (21 years ago, 16-Dec-03, to lugnet.robotics)

there's probably a way to use a light sensor to sense four different colored bricks. one for each direction. = sensor red ylw blue wht / ---\ /---- different heights of 'wedges' would lift a column, as a bumper is either slid in, or the bumper (...) (21 years ago, 16-Dec-03, to lugnet.robotics)
