Starter Models

After reading through Chapters 3 and 4 in the ROBO Pro Help, you will
be able to program some of the models in the construction set. Let's get
started. ROBO Pro has various levels, which you can select on the menu
bar. We will start with very simple programs at Level 1. Whenever you
have finished building and wiring a model, check whether all inputs and
outputs on the ROBOTICS TXT Controller are properly connected and if
the sensors, motors and lights all function properly with the aid of the
interface test.

Pedestrian light

A pedestrian light has been installed in front
of your house. Since the technician from the
traffic light company doesn't have much time,
you offer to program the traffic light control for him.
The man explains to you how the control is supposed to work. But first,
build the model.
Task: (Level1)
The traffic light should be red initially. When pushbutton I1 is
pressed by a pedestrian the traffic light should change to yellow
three seconds later and after an additional four seconds to red.
The green phase is to last for 10 seconds, before the light
turns red again.
Programming Tips:
The various LEDs are associated with the following outputs on the TXT
Controller.
▯ Red – M1
▯ Green – M2
Turn the indicator lights on and off one after another to obtain the
desired sequence.
You can load the finished program by clicking on the picture on the
right.
