Your next step will be to attach the Servo and Camera Assembly to the Chassis. See the image below to help you determine which materials to use.
Before you start attaching the assembly to the chassis, make sure to plug the Camera Assembly Servo into the D11 pins.
Place the Big Ring Washer in between the Chassis and the Camera Assembly Servo.
Hold the assembly in place with one hand and turn the Chassis over and tighten the Servo Screw.
