On July 1st, Tesla CEO Elon Musk shared a group photo of the team at his Fremont factory, revealing the production line for the Optimus humanoid robot, which was converted from the original Model S and Model X vehicle production lines. Musk stated that as a new product containing 10,000 unique parts, the initial production ramp-up speed of Optimus will be extremely slow, and the exact annual output this year is difficult to predict. According to Tesla's previous capacity planning and the timeline disclosed in the Q1 financial report, the robot is expected to start mass production in late July or early August this year, with initial low-volume production starting after the summer and transitioning to large-scale high-volume production by 2027.
