According to industry sources, Tesla’s robotics team began factory audits last week at supply chain companies such as Toupu Group, Sanhua Intelligent Control, and Joyson Electronics. These companies primarily supply core electromechanical components, including joint modules, actuators, and precision structural parts. “Prior to these factory audits, all of these companies had already received orders for Tesla’s humanoid robot, though the order volumes varied. The audits will assess the quality and compliance of the relevant production lines, and production will begin shortly after they are approved,” the source noted. The industry insider also stated that the factory audits are not limited to Ningbo, as rumored online; Tesla’s robotics team’s current visits also cover supply chain companies in the Yangtze River Delta region, including Hangzhou and Shanghai
