Market rumors suggest that Tesla has initiated a new round of quality audits for its robotics business production, while Tesla China has not responded to the matter. Sources from the local industrial chain in Ningbo confirmed that Tesla teams have inspected the robotics operations of several Ningbo-listed companies, including JOYSON ELEC. Many of these firms had previously collaborated with Tesla for years on new energy vehicle components, and some of their robotics parts could be adopted in Tesla's mass-produced humanoid robot Optimus.

In July of this year, JOYSON ELEC showcased its latest innovations at the 2026 World Artificial Intelligence Conference (WAIC), unveiling core component assembly solutions such as dexterous hands, solid-liquid hybrid batteries, third-generation AI head assemblies, electronic skin, and embodied intelligence brains, along with its newest results in robotics industrial scenario training and applications. The company also announced that its embodied intelligence business is accelerating commercial deployment, with controllers and other products already being mass-produced and delivered to leading robotics companies.
