Project guide

Servo Head

Do not use a Continuous Rotation Micro Servo (FS90R) for this project! The library and code does not currently support that type of servo.

Install Servo Horn

The micro servo comes with a variety of servo horns and mounting screws. Use the wide version and install it onto the teflon bushing. Install and fasten the shorter screw to secure the horn to the bushing.

Attach Servo to Head

Now we need to mount the servo horn to the bottom of the robots head. First, it's a good idea to tap the mounting holes on the bottom of the 3d printed part. Place the servo horn over two of the mounting holes and see where the holes can line up. Insert and fasten the machine screws into the tabs to secure the horn to the head.

Test Rotation

With the servo horn attached to the head, it's a good idea to test out the rotation by twisting the head back and forth. Ensure the wires from the LEDs are not tangling up with the servo horn or body.
