灵巧手专题系列报告1：从灵巧手专利拆解出发：看驱动及传动路径如何？

Investment Rating - The report maintains a "Recommended" rating for the humanoid robot industry, indicating a favorable outlook for investment opportunities in this sector [1][62]. Core Insights - The report highlights that dexterous hands, as end-effectors of robots, can be classified based on appearance, drive methods, and transmission methods. The mainstream types currently available in the market are primarily categorized as "biomimetic" combined with "motor" and either "linkage," "tendon," or "gear" transmission [6][7]. - The report discusses various drive solutions, including external wrist motors, finger root motors, and internal motors at finger joints, emphasizing the trade-off between the number of motors and degrees of freedom, where more motors lead to higher costs [6][8]. - It provides a detailed analysis of transmission methods, comparing linkage, tendon, and gear systems, each with its advantages and disadvantages in terms of stiffness, load capacity, manufacturing complexity, and cost [6][20]. - The report identifies key players in the dexterous hand market, including micro-motor suppliers and dexterous hand manufacturers, and suggests monitoring specific companies for investment opportunities [6][62]. Summary by Sections Section 1: Dexterous Hand Analysis - Dexterous hands are categorized based on appearance (grippers vs. biomimetic hands), drive methods (motor, hydraulic, pneumatic, artificial muscle), and transmission methods (gear, linkage, tendon) [7][8]. - The report emphasizes that the drive method of electric motors is the mainstream choice for biomimetic dexterous hands, with various configurations available depending on design and application [10][12]. Section 2: Patent Analysis - The report dissects patents from various companies, revealing that the dexterous hands primarily utilize biomimetic designs with at least three fingers and nine degrees of freedom, equipped with advanced sensor systems [28][29]. - It highlights Tesla's dexterous hand design, which incorporates built-in motors and gear systems for finger movement, showcasing innovative wiring methods for tendon-driven fingers [31][35]. Section 3: Related Companies and Investment Opportunities - The report lists several key companies in the humanoid robot sector, including micro-motor suppliers like Zhaowei Electromechanical and Mingzhi Electric, tendon and material suppliers like Nanshan Zhishang, and sensor suppliers like Keli Sensor [62][63]. - It provides financial forecasts for these companies, indicating their market capitalization and expected earnings for the coming years, which can guide investment decisions [63].
