Hi Vasilis and Jürgen, I think it can be done with only 1 thread in each. In my Java line follower, the main loop reads the light sensors (I use 2) and issues commands to the two motors. It should be possible to encode the commands into a byte and (...) (24 years ago, 23-Feb-02, to lugnet.robotics.rcx.java)
