# Installation Steps

## Essential Pre-Installation Reading:

1. Servos within this product require specific angle adjustments during installation. Please calibrate each servo to its designated angle as per the tutorial before fitting. Adjustment codes are provided at corresponding locations within the guide. Failure to calibrate may result in servo damage.

2. This product features multiple joint positions. Do not overtighten screws at any joint. Strictly follow the tutorial to distinguish between similar screws and their designated positions. Failure to do so may cause the product to malfunction and result in servo burnout.

3. During initial operation, monitor servo temperatures closely. Should temperatures become excessively high, immediately disconnect power without delay. Inspect the product's wiring and check whether any servos are jammed.

***Initialization of Servo Motor 4 (Left Servo Motor):***

(For a quick installation here, we shall proceed directly with the Makecode code for servo calibration.)

1. Connect the wires as shown in the diagram below, and connect the micro:bit main board to the computer.Once the connection is complete, you will notice a new drive letter named MICROBIT appearing under “This PC”.

3.Drag the downloaded code into the MICROBIT drive letter.

4.Upon completion of the code upload, you should hear the servo motor rotate once before stopping, confirming that the servo has been calibrated. (If no rotation is observed, this indicates the servo is already positioned at the specified angle. Do not alter the servo's angle until its installation is complete.)
