Electronic device having multiple motors in series connection, and motor number setting method for the same

An electronic device having multiple motors in series connection, comprising:

• multiple motors, each of the motors respectively having a motor number, and each of the motors is a servo motor having a microprocessor, firmware of the microprocessor has been pre-embedded with programing code related to a random numbering procedure;
• an MCU, configured to record a motor amount of the multiple motors and connected with the multiple motors in series connection through a communication port, and configured to scan the communication port for respectively obtaining the motor number of all motors which are in series connection with the communication port;
• wherein, the MCU is configured to determine whether an amount of different motor numbers is equal to the motor amount, and configured to send a random numbering command to a plurality of adjusting motors of the multiple motors that have an identical motor number when determining that the amount of different motor numbers is different from the motor amount;
• wherein, the microprocessor of each of the adjusting motors is respectively configured to perform the random numbering procedure for generating a new motor number according to the random numbering command;
• wherein, the MCU is configured to re-scan the communication port and send the random numbering command before determining that the amount of different motor numbers is equal to the motor amount.
