Using this table, all motors in the example programs can be programed.

The robot does not travel in a precise square. Check the following questions: What is
the cause? How can the result be improved?
Tip:
Synchronize the motors M1 and M2 using the push button switches I1 and I2 so that the model
travels exactly straight ahead. For this purpose, we have supplied a finished program, „forward_sync"
for you. Here you only have to enter the number of pulses as a constant in the orange subprogram
input (see Basic_Modell_4.rpp). You can also enter the number of pulses for the angle of rotation
in exactly the same way in the subprogram, „Turn_sync."

After you have experimented with the basic model enough, your robot is now to react to various signals
from an external source.
In order to allow your tracked vehicle to identify its environment and to complete certain tasks, you must
equip it with sensors. The following model suggestions show you different variations of tracked vehicles
with various sensors. This is to provide the capability to identify different paths, light and colors or even
heat sources or distances. You can find the individual programs in the directory:
C:\Programs\Robopro\SamplePrograms\Robo_Explorer\
Of course you have seen factory buildings, which have no human beings in them, in TV movies where the
transport vehicles in the buildings travel as if steered by the hand of a ghost. In some cases, such systems are
controlled by data lines, which are embedded in the floor, or by markings on the floor to indicate the path.
The basis of your programing is to be that the robot travels along a black line.
Before you start with the programing, first build the trail searcher using the construction instructions. You
can find an experiment course with a printed black line in the construction set. The line, which is to be
followed by the trail searcher, is to be straight at first.
