yes - have to use messages - there's an app somewhere that allows multiple RCXs to be RCed that was developed for BrickWars I think, multiple games pads on one PC control an RCX each. Principle is, each RCX is coded to obey a set of messages in a (...) (23 years ago, 21-Jun-02, to lugnet.robotics.rcx)

Hi, All. I'm having a problem with a rotation sensor and I was wondering if somebody already solved that. I have 2 rotation sensors. One of them works fine. The other one works well as a sensor but the rotating axle has considerable friction. Since (...) (23 years ago, 25-Jun-02, to lugnet.robotics)
