2025-07-07 00:51Investment Rating - The report does not explicitly provide an investment rating for the humanoid robot industry Core Insights - The humanoid robot transmission system is characterized by a mix of rotary and linear joints, with domestic companies favoring rotary modules while international firms like Tesla prefer linear actuators. The design trends indicate a shift towards hybrid systems for dexterous hands, driven by increasing demands for high degrees of freedom and precision [1][5][9] Summary by Sections Industry Overview - The humanoid robot industry is witnessing a convergence of technology standards, transmission schemes, and processing techniques, although a clear competitive landscape has yet to emerge. Continuous tracking is necessary to understand the evolving dynamics [1][2] Key Components and Cost Structure - Core components of humanoid robot transmission systems include lead screws, reducers, and bearings, which collectively account for over 30% of the hardware costs. The cost structure is still in flux as technology converges [2][3] Domestic vs. International Trends - Domestic companies focus on light-load industrial applications and consumer markets, utilizing mature rotary actuators. In contrast, international players like Tesla emphasize high-load industrial scenarios, favoring lead screw designs [6][8] Patent Activity - As of 2024, patent applications in China show a significant focus on perception systems and linear actuators, indicating substantial investment in these areas. Rotary actuators and dexterous hands have fewer related patents [12] Future Development Directions - The future of humanoid robots will revolve around cost reduction, structural design optimization, and material selection. Innovations in manufacturing processes, such as improved heat treatment for harmonic reducers, are critical for enhancing performance [13][15] Competitive Landscape - The competitive landscape for reducers is changing, with latecomers needing to establish customer loyalty and possess strong development capabilities to succeed. The lightweight material advancements, such as PEEK, are noteworthy for their potential to reduce energy consumption and improve efficiency [16][17] Application Scenarios - Different application scenarios dictate the choice of transmission schemes, with domestic firms focusing on simpler designs for home use, while international firms prioritize complex, high-load industrial applications [6][8] Investment Considerations - Investors should focus on new technologies, materials, and structural designs that could lead to non-linear cost changes and reshape the industry landscape. Companies that have converged on technology routes and possess competitive advantages are likely to outperform [21]
