Assemble and Use the Line Follower With Your GoPiGo3 Raspberry Pi Robot

Assemble and Use the Line Follower With Your GoPiGo3 Raspberry Pi Robot

Here we will show you how to assemble the GoPiGo Line Follower Kit and attach it to your GoPiGo3.

The Line Follower is a sensor that attaches to the GoPiGo robot car which enables the GoPiGo follow a line on the floor.

You can use it to program your GoPiGo to serve a drink across a room, learn the basics of how automated warehouse or self-driving cars work!

What You’ll Need

To assemble the GoPiGo Line Follower you will need the following:

  • A Dexter Industries Screwdriver that came with your GoPiGo3 (1)
  • 1 bag of screws and hardware (2)
  • 1 bag of acrylic parts (3)
  • 1 Line Follower Circuit Board (4)
  • 1 Sensor cable (5)

 

 

Assemble the Line Follower

1. The acrylic parts come with scratch-protective paper or plastic film.  Peel it off before continuing.  In some of the following steps, we have left the protective coating on to help show the acrylic in the step better.

2.  In this step we will line up the acrylic sensor protector.  Find the bottom of the Line Follower Circuit Board.  The bottom has five black colored plastic sensors on it.  Place the acrylic sensor protector on this side of the board and line the holes in the circuit board with the holes in the acrylic protector.

Take the long screws and slide them through the acrylic and then the PCB.

3.  Turn the Linefollower circuit board over, with the screws pointing upwards.  Find the hex posts, and the acrylic spacers.

In the above picture, the top arrow points towards the long screws pointing through the circuit board.  Take the acrylic spacers, and place them on the line follower.  Then take the hex posts and screw them onto the line follower.

Note that the line follower circuit board has orientation labels on it: left, right, and front of the sensor.

4.  Find the two line follower holes on the front of the GoPiGo3 body.  Remember that the front of the GoPiGo3 is the opposite end of the battery pack holder!

Line up the hex posts with these holes on the GoPiGo3.  Screw them in with the shorter screws that came with the Linefollower sensor.

5.  Connect the sensor to the GoPiGo3 Red Board.  The line follower is connected to the I2C port.  With the sensor cable included, connect the line follower to the GoPiGo3 board I2C port.
