LEGO RCX TURNTABLE MACHINE

Front Touch Sensor and Pen

LEGO RCX TURNTABLE ROBOT

 This Robot Is designed to draw in a circle as it drives forward.  It is a take off of my First LEGO Machine where it was controlled by one motor.  This Robot has 3 motors and 2 touch sensors.  It is controlled by a LEGO RCX 2.0 Programmable Brick.  2 of the motors control the drive of the tracks.  The tracks are controlled independently.  The third motor controls the pen.  The touch sensors are located in the front and rear of the Robot.  The Program for this Robot is designed to drive forward until the front touch sensor hits the frame of the drawing area.  This tells the Robot to back up strait for one second.  Then the "drivers" side track stops for two seconds while the passenger side tracks continues to drive backward.  After that both tracks drive backward until the rear touch censer is activated.  That causes the Robot to drive forward for one second then the passenger side track stops for 2.5 seconds.  After that both tracks start driving forward until the front sensor is activated and the whole process starts again.  The Robot keeps driving back and forth on the paper until someone stops the program or the battery dies.  I have run it non-stop for 15 minutes.  Below is a couple of videos of the robot running.
