And the third upgrading mode is continuously executed when the OTA software is set, when the central control display screen pops up the user authorized downloading interface, the cooperative mechanical arm automatically clicks to start downloading, and when the central control display screen pops up the user authorized upgrading interface after downloading is completed, the cooperative mechanical arm automatically clicks to start upgrading.
5. A readable storage medium having stored thereon a program or instructions which when executed by a processor performs the steps in the OTA upgrade method of any one of claims 1 to 3.
