Summary of Key Points from the Conference Call Industry Overview - The conference call discusses the robotics industry, specifically focusing on dexterous robotic hands and their driving solutions, including threaded screws, servo motors with lead screws, and micro electric cylinders [1][2]. Core Insights and Arguments - **Driving Solutions**: Various driving solutions have distinct advantages and disadvantages. Threaded screws have poor self-locking and precision, servo motors are slow with low load capacity, while micro electric cylinders are fast but costly [1]. - **Motor Types**: Hollow cup motors offer high speeds, but companies like Tesla may switch to standard brushless motors for cost considerations. The choice of motor depends on specific application needs and overall design strategy [1][7]. - **Dexterous Hand Design**: The mainstream design for dexterous hands is six degrees of freedom (DoF), with driving methods including rods, threaded screws (gear transmission), and tendon-driven systems. Each method has trade-offs in terms of efficiency, complexity, and load capacity [1][12]. - **Load Capacity**: A single finger can achieve a grip strength of 3 kg, while the entire hand can handle approximately 3 kg, making it suitable for various complex tasks [1][13]. - **Importance of Position Sensors**: Position sensors are crucial for the performance of dexterous hands, providing real-time feedback on finger load and tangential force. The company currently sources these sensors externally [1][16][18]. - **Cost Structure**: The price of dexterous hands ranges from 30,000 to 50,000 yuan, influenced by components like micro electric cylinders, push rods, and advanced control systems. R&D costs and material choices significantly impact overall costs [1][21][22]. Additional Important Content - **Market Applications**: The products are utilized in various sectors, including beauty and medical aesthetics, new energy coating automation, automotive, and robotics [1][11]. - **Mechanical Hand Degrees of Freedom**: Higher degrees of freedom in mechanical hands lead to increased weight, affecting load capacity and lifespan. The industry tends to favor lower DoF designs for practical applications [2][24]. - **Comparison of Driving Methods**: The market features several driving methods, including rods, threaded screws, and tendon-driven systems, each with unique advantages and disadvantages [1][14]. - **Future Directions**: The company is considering moving towards higher degrees of freedom in their product iterations, aligning with industry trends [1][37]. - **Competitive Landscape**: Companies like Tesla and others are developing various mechanical hand solutions, with differing degrees of freedom and driving methods, impacting their market viability [23][42]. This summary encapsulates the key points discussed in the conference call, providing insights into the robotics industry, particularly in the context of dexterous robotic hands and their applications.
