This thread seems to have been going on for such a while I've forgotten where it started. Was the original question: how does my robot know where it is in a room? Has anyone suggested ultrasonic (or audio) "beacons" in each corner of the room? The (...) (23 years ago, 26-Jun-02, to lugnet.robotics)

Yes, Gregory, I'm sure. When I mention the sensor I mean the whole thing, not only the eletronics part. I tested both sensors and I tried to tilt the axle to test the behaviour you mentioned.

Are you sure it is the sensor itself? We have found that the axis is often "off" a bit from canonical LEGO spacing, and if built into a structure, binds quite a bit. But if you assemble it so that the body (blue) of the sensor can "float" with (...) (23 years ago, 26-Jun-02, to lugnet.robotics)
