The US and China are in a fierce competition to lead in humanoid robotics, with Tesla's Optimus project aiming for 5,000 units by 2025, while China's Agibot and Unitree Robotics have set the same target. Unitree's G1 humanoid, priced at $16,000, undercuts Tesla's estimated $20,000 for the Optimus Gen2. China's rapid advancements are highlighted by 5,688 humanoid robot patents filed in five years, significantly outpacing the US's 1,483, bolstered by government support and integration into factories by major companies.
