How to assemble a line following robot – Page 2

See page 1

Remaining part of assembly of line following robot…

Fix the nut bolt set on the PCB

Solder the photo resistor/LDR as shown on the image.Make sure that the LDR is at least 5mm above the ground or spot where you are placing the robot.

Solder the transparent 5mm LEDs. The LEDs should be 5mm above the LDR.

Peel of the top sticker to stick the included battery holder

Pass the wires through the hole

And solder it as shown below

The package includes two wheels also.

Fix the wheels to the motors

This is how you insert the holes of the wheel to the motor

Use the screws to tighten the wheel to the motor

The line following robot is now ready. Make sure that you use a different switch as shown below

Make a track with a black insulating tape. You may use paint or permanent marker. I have one with a black insulating tape. Watch the following video:

The assembly of a line following robot is pretty straight forward. If you follow the silkscreen labels, you will be able to assemble it easily.

The line following robot comes with the components as shown on the image.

Start with resistors

Solder all the resistors that comes with the package.

Solder the transistors S8550

Solder the 5mm red LED. Make sure that the Anode and Cathode go into the right holes.

 

Solder the 100uF capacitors.

Solder the variable resistor 10K ohm

Solder 8 pin DIL socket

Solder wires on robot motors

Peel off the sticker and stick the motors

After sticking the motors, the robot should like this:

Make sure that the motors are soldered on the PCB solder pad.
