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)

Ed - Take a look at patch [568061] posted on SourceForge by 'Ingolf'. The problem looks easily resolved by changing the '/'s to '\'s.

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)

Wow! Jennifer, your work never ceases to amaze me. So much detail, so many complicated sub-systems, so little room for it all! Yet again another great model to marvel about. I'd like to also congratulate you on the excellent presentation you have (...) (23 years ago, 25-Jun-02, to lugnet.robotics)

Excellent explanation, Jennifer (and amazing model too!!!). I just want to note to everyone that LEGO themselves modifies their own parts in their theme parks. In California, they use machined parts and motors from a custom machine shop adjacent to (...) (23 years ago, 25-Jun-02, to lugnet.robotics)

(...) Mauro, sorry if it is obvious (I am anovice here) you could connect the two wheels' axles to a differential (reverse one of the rotations). If the differential's body is stationary, the two wheel are rotating at same speed. (23 years ago, 25-Jun-02, to lugnet.robotics)
