Line tracker Robot (with infrared system)
Arduino System
These instructions indicate how to build the same Arduino-type smart robot vehicle. It states how to
install step by step robot chassis, Arduino compatible motherboard, Shield module, geared motors, battery
holder and the other accessories as well as their wiring system.
With this project, you will learn how to program the Arduino system and its learning platform.
It should be noted that to assemble this kit, only a screwdriver is needed, NOT INCLUDED
included. All electrical and electronic parts can be connected or screwed into a terminal block or Clema.
The system of infrared light sensors which are installed on the front part basis, detects the black line
that you done on the floor with an adhesive tape forming a way. The intelligent robot will perfectly follow the
drawn path as complicated or long as it is.

INSTALLATION AND ASSEMBLY
Step 1: Chassis for the Arduino robot
We will use:
(1) Acrylic chassis for intelligent robot 1
(2) Acrylic support for motors 4
(3) Gearbox motor with double axis and cables 2
(4) Wheel Ø65mm with rubber tire 2
(5) M3 × 30 mm screws 4
(6) M3 Nuts 10
(7) M3 × 8 mm screws 4
(8) Robotic free wheel 1
(9) Tool needed: Screwdriver 1
Figure 1 –1 : Necessary pieces for the chassis assembly
Before to start the assembly, remove the acrylic protection film, as it is indicated hereafter.

It is recommended to fix the cable with a
hot melt adhesive

Mounting support and fixing of the motors
Figure 1- 6: Important
The chassis is not symmetrical. If you assemble
it upside down you will not be able to install the
control circuit board.
This image shows the chassis seen from the side
of the motors (lower side).
The inverted "L" shaped groove indicates the
correct position.
Figure 1- 7:
Insert one of the motor’s support from the
top of the chassis as shown in the figure.
Figure 1- 8:
Now, place the motor as shown in Figures 1-4 and 1-5
of the attached picture. The outgoing element must
always remain on the outside of the chassis. Then
place the other support, inserting it as indicated by
the arrow.

Figure 1- 9:
Then place one screw and one nut in the upper
hole and another in the lower hole.
See added picture
The lower nut will not turn once the screw is
tightened because it is in abutment with the
chassis.
Figure 1- 10:
Install the other motor following the same instructions as for the first one.
In the picture below, you can see the correct chassis position indicated by the inverted "L" shaped groove.
(View of the side of the motors)
If your chassis is assembled upside down, it will necessary to be disassemble and correctly reassembled it (see
Figure 1-6).

CAUTION: Disconnect the modules.
We will use:
（1）Control board Arduino type
1
（2）Shield Module
1
The Arduino main board is supplied already assembled with the Shield module in order to not damage
connectors.
It will be necessary to unplug them according to the following instructions:
Firstly : First: Strongly grasp the
two circuit boards as shown in the
picture.
Secondly : Carefully separate the two plates
by pulling on both circuits.
Thirdly: Be careful not to damage or bend the
connector contacts. Check one by one that all pins
are correctly aligned with the connector’s holes in
the main board.
These two points must be checked very carefully,
to avoid that a short circuit instantly destroyed it,
when the robot will be supplied.
