According to a report by Ningbo Evening News, Tesla is preparing for the mass production of its humanoid robot Optimus.
On the evening of September 20, Tesla China declined to comment on recent rumors that Tesla had launched a new round of factory audits for mass production of its robotics business.
However, a local industry source in Ningbo confirmed to the Shanghai Securities News that Tesla teams have inspected the robotics operations of Ningbo-listed firms including Joyson Electronics. Many of these listed companies have partnered with Tesla for years on new energy vehicle components and are poised to supply some robotic parts for Tesla’s mass-produced Optimus humanoid robot.

The same industry source added that besides Ningbo, Tesla teams will also conduct inspections in Guangdong and other regions.

Recent reports state that construction of the main structure of Tesla’s dedicated Optimus production line in Texas, USA, is nearly complete, marking a key milestone for the program.

Official figures show that Ningbo is home to nearly 1,000 auto parts manufacturers. Technologies used in automotive motors, electronic controls, chassis, shock absorption, precision casting and energy management share extensive similarities with those required for robotic joint actuators, body structural components, foot dampers, controllers and battery systems.

Industry experts told reporters that as intelligence advances, several Ningbo-listed enterprises have expanded from automotive businesses into robotics. Take Joyson Electronics as an example. This year the company rolled out a suite of core robotic components and system solutions, including dexterous hands, third-generation AI head assemblies, embodied intelligence brains, electronic skin, and solid-liquid hybrid batteries. Among them, the embodied intelligence brain solution EAOS+EAPC stands out as the core highlight of Joyson Electronics’ robotics push.
