Exercise 2. Press “Program” (the red flashing light
indicates that the program is being recorded) and then
the necessary buttons in order to create the following
sequence:
Ÿleft fan rotates clockwise;
Ÿboth fans rotate at the same time in any direction;
Ÿred LED on;
Ÿorange and green LEDs on at the same time.
Once you finish, press the “Program” button again to
save the program and then press the “Play” button to
check if the command sequence is correct. If you press
and hold the play button for longer time the program will go
into loop (endless repeat).
Exercise 3. Note that the ERP does not record the elapsed time
between the button pushes and it just plays all the
recordings without delay. Record again, but this time
add delay between each command of exercise 2 by
pushing the “Idle Time” button. Check the results on
your model.
Exercise 4. Record the following sequence in order to simulate
traffic lights control. Don’t forget to use appropriate times:
Ÿred light on (cars stop);
Ÿred and amber light on simultaneously (cars ready to go);
Ÿgreen light on (cars go);
Ÿamber light on (cars ready to stop);
Ÿred light on (cars stop).

2. Connect the ERP device with the PC
using the USB cable. Open the Engino
Robotics Platform Pro 1.2 software and
click the Connect USB button.
3. Click the “Receive Program” button,
so the recorded sequence is uploaded
on the computer. A vertical line of blocks
should appear, called “flow diagram”.
4. Click the “ERP Simulator view”
button and answer exercise 2.
5. Follow exercise 3 to learn more about the
action blocks and their variables on the flow
diagram. Make changes by dragging and
dropping the blocks. Right-click on each one
(motor, light, buzzer and idle), observe the
pop-up windows and complete the table.
6. Clear the screen by clicking the icon
“New”. Click the “Program” button on
the simulator (on the computer) and record
the same program as in procedure 1.
Observe what happens to the model and on
the screen.

(www.enginorobotics.com) and installed.
Output
Exercise 1. Push the buttons on the ERP device (input) and
write briefly the outcome you observe on the model (output).
Exercise 3. In the flow diagram, delete the first motor icon
(drag and drop in the bin) and add an “Idle” icon
(from the left). Tick the boxes below to indicate which variables
can be changed for each action block.
Exercise 1. Using the dinobot model record the following
sequence:
Ÿboth green LEDs on at the same time (eyes open);
Ÿmotor 2 rotates clockwise (mouth opens);
Ÿmotor 2 rotates anti-clockwise (mouth closes);
Ÿmotor 1 rotates clockwise (small legs move);
Ÿbuzzer on (dinobot roars).

Exercise 2. Drag and drop
the peripherals (motors,
LEDs and sensors) into the
ports of the ERP simulator,
according to the dinobot
model. Make sure that you
set them up correctly as this
affects the program and the
way your robot will behave.
Design them here as well.
Exercise 4. On the flow diagram make the following changes:
Ÿthe eyes light up at the same time and blink 2 times;
Ÿthe mouth opens and closes (use only one block);
Ÿthere is sound at the same time that the mouth moves;
Ÿthere is delay for 2 seconds and then the small legs move;
Ÿthe program should repeat for 2 times, not forever.
Tip: for this, right-click on the “start” block to choose
the number of repeats, also called loops.
A robotic system could not be complete without a programming
software. The ERP software is capable of receiving a recorded
program from the device or send a program to it. Wake up the
dinobot first manually and then through the software by using
the ERP simulator, the digital version of the actual ERP controller.

There are many ways to control your Engino robots. One of
them is through the EnginoRobot application for smart devices
®
with a wireless Bluetooth connection. Try also the Engino
GamePad within the software and notice the difference between
manual button control and digital programming.
Decision making is what distinguishes a real robot from an
automated machine. This task is made possible by sensors which
receive feedback from the environment helping the robot to
decide what action to follow according to its program. Learn
about the touch sensor and the IF conditional statement below.

Exercise 1. On the computer, place the correct icons on the
ERP simulator according to the jeep car robot model. Drag and
drop the necessary blocks inside the flow diagram in order to
create the following program:
Ÿthe jeep moves forward for 3 seconds and the front LED lights
are both on at the same time.
Tip: use a “function” block to save the subprogram “move
forward”. Use the after/with previous command accordingly
and set the program to activate only once.
Exercise 2. Place an obstacle in front of the jeep car robot.
Make the necessary changes on the program of exercise
1 above so that:
Ÿthe jeep moves forward for 3 seconds and the front LED lights
are both on at the same time until it gets close to the obstacle;
Ÿthe jeep moves backwards for 1 second with all lights on;
Ÿthe jeep turns 90 degrees to the right with front LED lights on.
Tip: in order for the jeep to turn, you can either set the wheels
to turn in reverse or stop one wheel from moving altogether.
Also, conduct several tests to adjust the appropriate time
needed to turn.
Exercise 3. Drag and drop the IF statement block in the
flow diagram. Right-click on it and write below which
variables can be modified (ignore “advanced” tab).

.......................................................................................................
Exercise 4. Use blocks inside the IF statement so that:
Ÿthe jeep moves forward continuously and the front LED lights
are both on at the same time;
Ÿif the touch sensor is pushed, then the jeep should go
backwards for 1 second with all lights on and turn 90 degrees
to the right with front LED lights on.
Tip: place the blocks that you used in exercise 2 inside the If
statement and change the program so that it repeats forever.
Exercise 5. Drop the blocks inside the IF/ELSE statement so:
Ÿthe jeep moves forward continuously and the front LED lights
are both on at the same time;
Ÿif the touch sensor is pushed, then it should go backwards for 1
second with all lights on and turn 90 degrees to the right with
front lights on. Else an interrupted beep should sound.

Materials Needed:
®
- Engino Robotics PRO (STEM70).
- Computer with ERP software installed.
- 4 x A3 white carton papers.
- Black sticky tape or black marker.
- 1 small water bottle (half full with 250 mL).
Procedure:
1. Find the instructions in pages 56-58 and
build the humanoid robot model.
2. Stick the A3 papers together as to create a
big white rectangle. Draw a black ellipse, 5cm
thick, using a marker or sticky tape (see
picture on the right). You can also download
another path at www.enginorobotics.com
(teaching resources).
3. Open the ERP PRO 1.2
software and follow the
instructions in exercise 1,
in order to create a black
line following program.
For this, the two IR sensors should face the
ground, so turn them downwards.
4. Read exercise 2 in order to transform
your humanoid into an object detecting
robot. For this, turn the two IR sensors to
face forward. Once you create the program,
test it by placing four white objects (as tall as
the height of the sensors) as to create an
imaginary square for the robot to move
along its sides (see picture on the right).
Procedure:
1. Find the instructions in pages 59-63 and
build the grabber robot model.
2. Follow exercise 1 in order to
create a loop program using the
“repeat” block.
3. Sometimes we need a loop to be
executed continuously until a
sensor’s condition is met. Follow
exercise 2 to learn how to do this
using the “repeat until” block.
4. Stick the A3 pieces of papers together as
to create a big white rectangle. Draw a black
half circle ending with two vertical lines and a
red circle, as you see in the next picture. Or
download this at www.enginorobotics.com
(teaching resources). The grip should be in
the circle when the grabber stops on a line.
Place the bottle on the red circle.
5. Read exercise 3 in order to make a
robotic carrying device that would pick up
the bottle and take it to the other side.
Exercise 1. On the computer, place the correct icons on the
ERP simulator according to the humanoid robot model. Drag
and drop the necessary blocks inside the flow diagram in order
to create the following program:
Ÿwhile the IR sensor in port 2 detects black colour, the motor in
port B should move the humanoid forward and both lights
should be on;
Ÿwhile the IR sensor in port 4 detects black colour, the motor in
port A should move the humanoid forward and both lights
should be on.
Once you place the appropriate blocks, you will need to
configure the infrared sensors, so that they follow black
line. For this, consult the user manual under the section
“Sensors / Infrared sensor configuration” in pages 25-26.
With this program
the humanoid will
follow a black line.
In order to test
your program,
place your robot
on the black
ellipse you
created and see if
it goes around
with its lights on.
Exercise 1. On the computer, place the correct icons on the
ERP simulator according to the grabber robot model. Drag and
drop the necessary blocks inside the flow diagram in order to
create the following program:
Ÿthe grabber should move forward for 2 seconds precisely. This
should be repeated 5 times.
Ÿwhen the loop finishes the buzzer should sound for 2 seconds.
Tip: change the variable of the “start” block from “forever” to “1”
and use the “repeat” block to create the program.
Exercise 2. Drag and drop the necessary blocks inside the flow
diagram in order to create the following program:
Ÿhumanoid moves forward;
Ÿif it detects a white object with either sensor or both, the robot
should stop and warn with beeping sound and lights on;
Ÿafter 5 seconds the humanoid should turn 90 degrees to the
right in order to detect the next object.
Exercise 2. Create the following program (the grip of the
grabber should be open at the beginning):
Ÿthe grabber should move forward continuously until the touch
sensor is pressed.
Ÿwhen the touch sensor is pressed, the grabber should stop and
the grip should close with beeping sound.
Tip: change the variable of the “start” block from “forever” to “1”
and use the “repeat until” block.
Exercise 3. Create the following program (the grip of the
grabber should be open at the beginning):
Ÿwhile the IR sensor in port 2 detects white colour, the motor in
port A should move the grabber forward;
Ÿwhile the IR sensor in port 4 detects white colour, the motor in
port C should move the grabber forward;
Ÿif the touch sensor is pressed, the grip should close and grab
the bottle. Then the grabber should turn around for a specific
amount of time until it finds the black line;
Ÿthe program will be considered successful if the model reaches
the other black line.
With this program
the grabber will
follow the line by
avoiding the black
colour, pick up the
bottle and go
back. Place your
model on the
paper and see If it
works.

Tips: the angle is always the
same, so only one program is
needed for turning. To set
both or either sensor to
detect objects you must
choose the appropriate logic
gate (AND or OR). You should
also configure the sensors
again so they will activate on
object detection this time.
How to use the infrared sensor.
What a WHILE conditional statement is.
What logic gates are.
What a REPEAT statement is.
What a REPEAT UNTIL conditional
statement is.
Infrared sensors are used very frequently in robotics in two very
important applications: for distinguishing between black and
white colours and for object detection. Try both programming
challenges and learn how to configure the IR sensors, how to use
the WHILE conditional statement and logic gates.
Doing repetitive tasks with precision is one of the most important
features in programming and robotics. We can create a program
and make it repeat many times, thus entering into a “loop”. Find
out how to create loops with the ERP and how the robot can get
out of it and continue with the rest of the program.
