How to assemble the servo package for the GoPiGo Raspberry Pi Robot.

Click on any of the images below for a more detailed view of the process.  You can find the Servo Package here.

1. Unpackage the Servo Package

Open up the contents of the servo and separate them out.  You should have two bags of screws, a bag of acrylic parts, and a servo package.

Find the two acrylic “T”‘s and the faceplate.

 

2.  Assemble the Servo Package

First, place the servo into the faceplate.  Three pictures are shown below of the servo placed into the faceplate.  The ledge of the servo, opposite the servo shaft (the white piece of plastic coming out of the servo), should be placed through the slot on the bottom of the acrylic faceplate.

Slide the two “T”‘s provided in, through the front of the faceplate, alongside the servo.

“T”s are shown inserted correctly here.

 

Place the long screw supplied with the servo package through the two holes at the end of the “T”s.

Connect the servo lip to the servo with a small woodscrew.

Take one of the small woodscrews and connect the servo to the servo lip.

3.  Attach the Servo to the GoPiGo Chassis

The GoPiGo has two places where the servo can be attached.  One slot on top canopy, and one slot on the bottom chassis.

Open up the holes in the servo lip by screwing in one of the included large woodscrews.  Pick two holes on the lip, screw the woodscrew in, and unscrew it.

Invert the GoPiGo.  Screw the servo into the slot running down the GoPiGo.

 

Add a second screw for more stability.

Turn it right-side up.

 

4. Connect the Servo to the GoPiGo Board

Finally, electrically connect the servo to the GoPiGo.

GoPiGo1

These instructions are for the GoPiGo1.  The servo cable orientation is reversed on the GoPiGo2.  The brown wire is ground, and this should be connected to the GoPiGo board so that it’s facing the small robot painted on the board.  In the picture below, the brown wire and the robot are pointed to by two red arrows.

GoPiGo2

These instructions are for the GoPiGo2.  The servo cable orientation is reversed from the GoPiGo1.  The servo cable connects on the bottom of the GoPiGo2.  The brown wire is ground, and this should be connected to the GoPiGo board so that it’s facing away from the small robot painted on the board.
