Attaching to the Torso
We finished making the visor, but we need to attach it to the torso !
So let's add the rest of the head to the torso !
Add the backplate
We'll start by adding the back of the head.
For this step, you'll need:
| Ressource | Quantity |
|---|---|
Torso-Bottom part | 1 |
Backplate part | 1 |
M2.5 x 4mm screws | 4 |
Place the backplate on the torso
Align the Backplate part with the front of the Torso-Bottom part.
Make sure the holes of the backplate are aligned with the holes of the torso.
Screw the backplate
Screw the Backplate part to the front of the Torso-Bottom part using four M2.5 x 4mm screws.
Tighten the screws until the backplate is snug against the torso, but avoid overtightening to prevent damage to the parts.
Add the Bottom Cover
The Backplate is now in place, let's add the bottom cover now !
For this step, you'll need:
| Ressource | Quantity |
|---|---|
Bottom-Cover part | 1 |
M2.5 x 4mm screws | 2 |
Place the bottom cover on the Backplate
Place the Bottom-Cover part on the bottom of the Backplate part.
Make sure the two holes of the bottom cover are aligned with the two holes at the bottom of the backplate.
Screw the bottom cover
Screw the Bottom-Cover part in place using two M2.5 x 4mm screws.
As always, tighten the screws until the bottom cover is snug but avoid overtightening them !
Place the Speaker
Let's place the components of the head, starting with the speaker !
For this step, you'll need:
| Ressource | Quantity |
|---|---|
Speaker component | 1 |
Remove the adhesive protection
As for the antenna, the speaker has some adhesive on its front side.
Peel off the protective film to expose the adhesive, and be careful not to touch it !
Place the speaker on the backplate
Align the speaker with its slot on the backplate, with its wires going downwards.
Make sure to clear any wire or dust from the backplate to ensure a good adhesion of the speaker.
Press the speaker in place
If the speaker is properly aligned, you can now press it firmly against the backplate to make sure it sticks well.
You can apply pressure for a couple of seconds, but you don't need to hold it for too long, as the adhesive should bond quickly.
Install the ears motors
We'll now add the two ear motors to the backplate.
For this step, you'll need:
| Ressource | Quantity |
|---|---|
SG90 Servomotor | 2 |
M2x7mm screws (from the servo bag) | 4 |
Place the left ear motor on the backplate
Place the Left Ear Motor on the left side of the backplate, with its shaft on the upper side.
Make sure the holes of the motor are aligned with the holes of the backplate.
Screw the left ear motor
Screw the Left Ear Motor in place using two M2x7mm screws.
Tighten the screws until the motor is snug against the backplate, but avoid overtightening them !
Place the right ear motor on the backplate
Do the same for the Right Ear Motor, but place it on the right side of the backplate, with its shaft on the upper side.
Make sure the holes of the motor are aligned with the holes of the backplate.
Screw the right ear motor
Screw the Right Ear Motor in place using two M2x7mm screws.
Tighten them until the motor is snug against the backplate, but avoid overtightening to prevent damage to the parts.
Connect the left ear motor
Pull the Left Ear Motor cable through the hole of the backplate and connect it to the Motor Driver board.
Make sure the connectors are in the right orientation, with the orange wire (signal) on the left side.
Connect the right ear motor

Make sure the connectors are in the right orientation, with the orange wire (signal) on the left side.
Verification
The base of the head is now complete ! But just before finishing the assembly, let's make sure everything is properly installed and secured.
Here's what you should have at this point:
Okay, let's finish the head now !
