It sounds like you're saying that the intermediate resistance values happen only for some period of time (short by human standards) while the touch sensor "switches" from "on" to "off" or vice versa. Other people writing in this thread have (...) (25 years ago, 25-Aug-99, to lugnet.robotics)

| | | | (...) I don't doubt that there are reasonable creations that e.g. press a touch sensor button halfway for extended periods of time, but I can't think of any off the top of my head. Can anybody help me out here? My point was that in what I would (...) (25 years ago, 26-Aug-99, to lugnet.robotics)

I measured a faster waveforms for now, but might give it another go with a longer waveforms and higher (...) (25 years ago, 26-Aug-99, to lugnet.robotics)

| | | | (...) (snip) (...) I managed to use this touch sensor "feature" as sort of a poor man's bend sensor to improve my wall-following robot. It's a torbot-type design with a left and right feeler-type bumpers in front. Using NQC (thanks, Dave) I set the (...) (25 years ago, 27-Aug-99, to lugnet.robotics)

| | | | (...) I gather the lever arms of the feelers gave you enough control over the touch sensor to stay mostly in the 100 to 110 range? It would seem to be difficult to keep the touch sensor in that position for long periods of time, since the sensor is (...) (25 years ago, 28-Aug-99, to lugnet.robotics)
