 | | touch sensors - two at a time ?
|
| I'm trying to build a sensor apparatus at the front of my bot, and it works, mostly. It's made up as a pair of touch sensors. The idea being that if one is activated, it turns around slightly, to avoid the sensor, but if both are activated, we (...) (25 years ago, 29-Dec-99, to lugnet.robotics.rcx.legos)
