Core Viewpoint - The joint module, as a core motion component of humanoid robots, significantly impacts overall performance and industry development. The market demand for joint modules is expected to grow, with a projected demand of 4.82 million sets and a market size exceeding 68.9 billion yuan in five years. However, challenges such as technology optimization, cost control, and scene adaptability remain prevalent in the industry [1]. Group 1: Market Demand and Challenges - The demand for joint modules is anticipated to reach 4.82 million sets in five years, with a market size projected to exceed 68.9 billion yuan [1]. - The industry faces challenges including technology optimization, cost control, and scene adaptability, as evidenced by an international humanoid robot manufacturer planning a technical route reconstruction for its third-generation product due to high costs and inadequate adaptability of its second-generation product [1]. Group 2: Strategic Cooperation - Jiangsu Donghua Testing Technology Co., Ltd. and Nantong Zhenkang Machinery Co., Ltd. have signed a strategic cooperation agreement focusing on the R&D and industrialization of humanoid robot joint module technology [3]. - The cooperation aims to leverage each company's technological strengths to enhance the testing control platform for rotary joint modules and explore opportunities in high-precision actuators and intelligent modules for industrial and humanoid robots [3]. Group 3: Technical Complementarity - The collaboration between Donghua Testing and Nantong Zhenkang is based on their complementary technological capabilities in humanoid robot joint modules, focusing on four promising technical directions: dual rigid wheel harmonic modules, planetary roller screw modules, RV reducer modules, and micro screw modules [3]. - Nantong Zhenkang identifies the RV reducer module as the optimal solution for key humanoid robot joints, having mastered the core technology for products with a diameter of 50mm, which offers multiple advantages after structural optimization and lightweight improvements [3]. Group 4: Donghua Testing's Expertise - Donghua Testing specializes in intelligent measurement and control systems, with over 30 years of experience in structural mechanics performance research, testing, simulation analysis, and custom measurement and control systems [5]. - The company's high-precision sensor products, including six-dimensional force sensors, achieve linear accuracy of 0.3% FS, meeting international standards and ensuring reliable performance in complex environments [6][7]. Group 5: Synergistic Model and Industry Impact - The strategic cooperation forms a synergistic model of "joint module core structure R&D + high-precision measurement and control technology support," addressing multiple technical pain points in joint module development [9]. - The collaboration is expected to lead to significant improvements in the performance stability and reliability of joint modules, ultimately driving the humanoid robot industry towards higher precision, reliability, and lower costs [15].
