再Call灵巧手：本轮T链灵巧手的重要性再探讨！

Summary of Conference Call on Dexterous Hands Technology Industry and Company Involved - The discussion centers around the humanoid robot industry, specifically focusing on the technology of dexterous hands, which are crucial for fine manipulation tasks in humanoid robots. Core Points and Arguments - Importance of Dexterous Hands: The dexterous hand is identified as a key technology bottleneck affecting product release timelines. Delays in product launches are primarily attributed to the performance and lifespan of dexterous hands, necessitating the search for new suppliers [1][3]. - Technical Complexity: Each humanoid robot's two hands require approximately 50 actuators, with each hand and forearm needing about 25 actuators. These actuators consist mainly of motors, micro-screws, tendons, and may include electronic skin technology [4][5]. - Upcoming Milestones: Most companies are expected to send samples to overseas clients by mid-November 2025, with feedback anticipated by the end of November. Successful feedback could lead to fixed orders by the end of the year, making the supply chain for core components critical to monitor leading up to the product release in early 2026 [6]. Observations on Supply Chain - Component Variability: There may be changes in the supply chain for components such as motors, micro-screws, and electronic skin, including variations in increments, diameters, or torque adjustments. Investors should closely observe these technical parameter changes [6]. Investment Recommendations - Key Companies to Watch: - Micro-Screws: Focus on Hengli Hydraulic, which has shown significant progress in this area, in addition to Zhejiang Rongtai [7]. - Electronic Skin: Hanwei Technology is highlighted as a promising company that may integrate electronic skin into dexterous hands [7]. - Tendons and Motors: Attention is drawn to Nanshan Zhishang, Mingzhi Electric, and Weichuang Electric, which are expected to become new members of the supply chain and present substantial investment potential [7]. Additional Insights - Broader Opportunities: The current phase presents significant opportunities within both international and domestic supply chains for dexterous hands, emphasizing the importance of structural design, core supplier selection, and various parameters for future investments [2][7].
