I did something simple in my book where each robot had an angle sensor, and could copy each other's 1D movement. Some grad students at Tufts did the same thing with 2 angle sensors on each robot and 2D movement. Both projects also then expanded to (...) (23 years ago, 27-Feb-02, to lugnet.robotics.rcx.java)

I have found that between a rather old PC and a RCX I cannot use quad speed transfer of data as the RCX cannot keep up. When a different (faster) PC and the same RCX I can use quad speed transfer. I guess it comes down to protocol timing. LNP does (...) (23 years ago, 26-Feb-02, to lugnet.robotics.rcx.legos)
