Tesla's humanoid robot model, the Tesla Bot, which is currently out of stock on the official website, is selling at a premium on China's second-hand trading sites.

Humanoid robots are the intersection of three core competencies: technology, manufacturing, and service, and the best demonstration of the integration of hardware and software with AI technology, as it's said in an industry paper. Automobile manufacturers are focusing on the development of humanoid robots because, as mimics of human anthropomorphism, they can seamlessly replace human work in numerous scenarios, unlike traditional robots such as robotic arms. Since the general assembly segment is still labor-intensive in the automotive manufacturing process, only humanoid robots can replace it, as it is difficult for current robotic arms to manage complex and delicate work. Furthermore, autonomous driving technology and humanoid robots share similarities, as the production of bionic robots can incorporate autonomous driving technology. Thus, humanoid robots have emerged as the ideal product for numerous technology companies and industrial leaders to demonstrate their extensive research and development capabilities, with automobile manufacturers such as Tesla, Xiaomi, and Xpeng serving as key representatives. Tesla, the first car company to develop a humanoid robot, first proposed the concept of Optimus in August 2021 and released the prototype in September 2022. At Tesla's shareholders' meeting in 2023, the Optimus evolved quite a bit, with its footsteps smoother and its movements more skillful. It was also capable of autonomously categorizing objects. Early in 2018, Xiaomi, a domestic smartphone and smart hardware company, established a robotics laboratory, and in 2021, it released the first generation of quadrupedal robot CyberDog to the public. CyberOne, a full-size humanoid bionic robot, made its public debut in August 2022, even before Tesla's Optimus. Ti Gong
