In recent months, Tesla's Optimus humanoid robot has witnessed a roughly tenfold surge in its production volume. Yet, achieving stable and large-scale mass production remains a formidable challenge, as production lines are hampered by the precision requirements of hand components, limitations in automation equipment, and supply chain constraints. Last month, its weekly production output climbed to several hundred units, marking a substantial rise from the mere dozens produced in the second quarter. Tesla aims to set up an automated continuous production line by the year's end, with the goal of surpassing 1,000 units per week. However, this falls well short of the long-term target of 20,000 units weekly. Elon Musk has consistently underscored the significance of Optimus to Tesla, asserting that it will spearhead the company's metamorphosis into an artificial intelligence powerhouse. Nevertheless, the project's timeline has undergone multiple revisions, with certain demonstration milestones failing to materialize as planned. Musk has also conceded the manufacturing hurdles and the challenges associated with ramping up production. At present, the Optimus V3 rolling off the Fremont factory assembly line is not the ultimate commercial iteration and is still undergoing rigorous debugging. It is predominantly utilized for internal testing, model training, and data collection, performing specific tasks solely within tightly controlled environments. Initially, Tesla intends to lease the robot to external commercial customers and has already pinpointed a pool of potential clients.
