P r o g r a m i n g Ti p s :
• It is best to use a separate subprogram for the code lock.
• Chapter 5.7 of the ROBO Pro handbook describes some possibilities for the construction of a
code lock.
• The code is entered using six buttons.
• Using a command, "Text," and a display element you can output a message to show if the
code entered was right or wrong.
• Sample program: Car park barrier 2.rpp
The shop, which was mentioned before, has also purchased another
welding robot. Since the owner was amazed at how you recently
programed his punch press, he asks
you if you would place his
welding robot in operation.
First, set up the model according
to the construction instructions.
Ta s k :
The robot is to attach a cover to a metal housing with a spot weld at a different
position for each metal housing in a set of three metal housings.
The welding rod is simulated by a lens tip light and the three metal housings by
yellow building blocks.
The robot is to move to the three positions one after the other and make a spot weld
at each position.
Then, it is to return to its starting position and start from the beginning again.
P r o g r a m i n g Ti p s :
• First, move the robot to its starting position.
• To move to the various positions, you use the element, impulse counter.
• Just experiment to find out how many impulses are needed for what position.
• For the welding process, you use a subprogram, in which you make the indicator light blink several
times.
• Sample program: Welding robot.rpp
