It will simply mean that at the end of your turn, you need to short the circuit (or brake the motor or touch the sensor) and then release it again so you’re able to receive the signal back from the other bot. We could make it so that your ‘turn time’ starts once your opponent is off the sensor.

Here’s a picture of what I mean: (I only have 1 RCX, so sensor ports 1 and 3 represent the two different bots. If either sensor gets pressed, both ports register it.)



This looks like a good scheme, but I don’t think it helps to have ‘my’ sensor port connected to ‘your’ sensor port.

If you have a touch sensor connected to my sensor input, you can send me a signal. At the same time, if I have a wire from your input to my robot (touch sensor or motor output), then I can send you a signal. These will both work at the same time.

The only real advantage to this set-up is that only one wire will travel between robots. But I don’t think that really matters, in this case.

The basic idea is still for me to open/close one sensor input on your RCX, when I’m finished.

(...) The other advantage is that this way I can still use that sensor for homing rather than it just being a dud. (...) Yup. But it needs to be clarified how soon that sensor is to be open again... because whether two wires or one, it's important (...) (21 years ago, 25-Sep-03, to lugnet.org.ca.rtltoronto, FTX)
