The sensor for distance measurement and the NTC resistor offer you additional possibilities to expand
your model to a professional robot.
Measuring distances and temperatures and initiating possible
rescue measures. What do you think, where could robots with
such capabilities be used? Of course, you can think of various
areas, where they could be used. We want to examine the area of
fire protection and fire fighting in auto and train tunnels.
The task for such a robot is to approach the source of the fire,
measure temperatures in the tunnel and to report data to a control center. In most cases, the robots are
equipped with mobile extinguishing equipment, which can be used depending on the conditions.
Now here conscientiously build the model, „tunnel robot," according to the construction instructions as
well. The distance sensor is connected to the connections D1.
Task 1 ROBO Pro Level 2
Similr to the trail searcher, which travels along a line, your robot is travel a certain
route along a wall at a certain distance of about 20 centimeters.
Finished Program: Tunnel_1.rpp
Let's examine a fire extinguisher robot once again for the next task. In order that it can travel along the
wall like your robot, it uses distance sensors. However, in order to identify the source of the fire, it employs
heat sensors. This heat sensor is the NTC resistor for your model. The physical characteristic of this
component is that the resistance value decreases when the temperature increases. You can try out this
change again with the interface test. Connect the NTC resistor to the connection, AY. Hold a heat source
close to the NTC and observe the blue bar for AY.
Task 2 ROBO Pro Level 2
Expand the program, which allows the robot to travel along the tunnel wall. As an
addition, measure the current heat with the AY connection. If this increases to a certain
value then the robot is to stop and transmit a warning signal using the buzzer. At the
same time as the buzzer, the red indicator light is to blink.
Following this simulated extinguishing action, your robot is to turn and return to
the starting point.
Finished Program: Tunnel_2.rpp
