Core Viewpoint - The development of Tesla's third-generation humanoid robot, Optimus, has been delayed due to challenges in developing a dexterous hand, which is crucial for the robot's functionality and market application [1][3]. Market Overview - The global market for dexterous hands is rapidly expanding, with projections indicating a market size of 700 million yuan by 2025 and potentially exceeding 20 billion yuan by 2030 [3][21]. - Dexterous hands account for 15%-30% of the total cost of humanoid robots, making their development and cost reduction critical for the commercialization of humanoid robots [3][17]. Product Innovation - The Linker Hand O6, developed by Lingxin Qiaoshou, weighs only 370 grams and can support a load of 50 kg, setting a record for the lightest mass-produced dexterous hand globally, priced at 6,666 yuan [1][4][17]. - The design of Linker Hand O6 targets medium-sized humanoid robots (1-1.6 meters tall) and emphasizes a "lightweight yet powerful" approach [4][7]. Technical Challenges - Achieving extreme lightweight in dexterous hands involves overcoming multiple technical challenges, including material selection and structural design [9][10]. - The use of advanced materials like PEEK and magnesium alloys has been pivotal in reducing weight while maintaining strength and durability [10][18]. Application and Impact - The lightweight design of Linker Hand O6 enhances the operational capabilities of humanoid robots, making them more effective in interacting with the physical world [7][15]. - In the prosthetics field, the reduced weight of Linker Hand O6 significantly improves user comfort and willingness to use, compared to traditional prosthetics that often exceed one kilogram [7][15]. Cost Reduction and Market Accessibility - The price reduction of dexterous hands, exemplified by Linker Hand O6, is expected to facilitate broader adoption of humanoid robots across various sectors, including industrial and service industries [17][20]. - The cost of high-performance dexterous hands has historically been a barrier to commercialization, with previous models priced at tens of thousands of dollars; however, the new pricing strategy aims to make these technologies more accessible [17][20]. Future Trends - The dexterous hand market is projected to grow significantly, with estimates suggesting a market capacity of 760,100 units and a market size of 1.706 billion USD by 2024 [21]. - Future developments in the dexterous hand sector are expected to focus on standardization, application-specific designs, and integration of AI technologies, enhancing their functionality and market appeal [22].
