The .java files here are ones written for LeJOS
 the Lego Java Operating System.

 LeJOS comes with classes that operate on the 
 Lego RCX programmable brick, including ones
 to run the motors, beep the beeper, examine the sensors, etc.

 The josx/platform/rcs directory here contains some dummy
 versions of these classes, just so that the routines here
 can be compiled under Java.  The dummy versions mostly
 just print to standard output what the real ones would be
 doing, i.e. "Motor A is turning forward.".  

 To compile and run JimsRobot.java and RunJimsRoboto.java,
 under Java, here on akbar, I typed the following at the command line.

    javac JimsRobot.java
    javac RunJimsRobot.java
    java RunJimsRobot

 To run this on one of a Lego robot,

   (0) Build a robot that has runs two motors, attached to the
       A and B connections, one on each side of the brick.
       (Depending on how left and right connect to A and B, 
       and which way you make the connections, your robot
       may not move or turn in the same direction as mine.  
       Experiment.)
   (1) Download JimsRobot.java and RunJimsRobot.java to
       one of the PC's that has LeJOS installed, with an 
       IR tower connected to it.
   (2) Compile the programs from the command line with
         lejosc JimsRobot.java
         lejosc RunJimsRobot.java
   (3) Turn on the lego brick, and put it near the tower.
       If the LeJOS firmware isn't already on the brick,
       put it on by typing "lejosfirmdl" at the command prompt.
   (4) Download the program into the brick by typing
         lejos JimsRobot
   (5) Push the "Run" button on the brick to see the robot
       do its thing.
