Barrier

Such a barrier is frequently located at the
entrance or exit to a parking lot. First, build
the model as described in the assembly
instructions.
Our barrier could be at the exit.
Task: (Level 2)
When a car approaches the barrier, it interrupts a light barrier. This
should open the barrier, leave it open a certain time (e.g. 5 seconds)
and then close it again; however only when the light barrier is not
interrupted, because otherwise the barrier could damage a car
located exactly below the bar. The traffic light should turn green to
show the car driver that the barrier is open and red when it is
closed.
Programming Tips:
Use a subroutine for the "opening" and "closing" operations for the
barrier (see also ROBO Pro Help Chap. 4).
For this purpose set ROBO Pro to Level 2.
You can open the finished program by clicking on the icon on the
right.
