Summary of Zhaowei Electromechanical Conference Call Company Overview - The conference call discusses Zhaowei Electromechanical, focusing on its innovative micro-drive technology for dexterous hands, which is a significant advancement in the field of robotics and automation [1][2]. Key Points and Arguments - Unique Micro-Drive Technology: Zhaowei's dexterous hand features 17 actuators, allowing independent movement of each finger joint, enhancing flexibility and functionality [3][4]. - Modular Design: The dexterous hand is designed with a modular approach, enabling each joint to operate independently without coupling, which facilitates complex movements [3][4]. - Innovative Linear Stepper Motor: Zhaowei has developed a new type of linear stepper motor that converts rotational motion into linear motion, significantly reducing device length and improving efficiency and precision [3][5]. - Material Selection: The use of high polymer plastics for the drive nut and metal alloys for the screw enhances transmission efficiency, reduces wear, and decreases weight, which is crucial for the dexterous hand's performance [6][7]. - Weight and Load Capacity: The dexterous hand weighs less than 1,000 grams and can support a load of up to 3 kilograms, with a maximum of 20 degrees of freedom, making it highly functional [3][4]. - Sensor Integration: Each joint is equipped with sensors, including those in the fingertips and palm, improving the hand's ability to perceive its environment and its own state [4][3]. - Different Versions: The standard version includes 17 motors and actuators, while the advanced version adds lateral movement capabilities with a total of 20 actuators. The low-end version uses a non-powered coupling mechanism [9][3]. - Research and Development Strength: Zhaowei demonstrates strong R&D capabilities in the micro-drive field, with its innovative linear stepper motor being a market first, indicating potential for continued market leadership [10][3]. Additional Important Content - Design Features: The dexterous hand incorporates two types of linear actuators: traditional electric cylinders and Zhaowei's designed linear stepper motors, which are compact and highly integrated [8][3]. - Advanced Control System: The control system utilizes multi-layer PCB design, allowing a single mainboard to control multiple actuators, achieving high integration and performance [8][3]. - Exploration of New Materials: Zhaowei is exploring the use of PEK (polyether ether ketone) for screw materials, which, despite low market acceptance, shows promise for future applications [7][3].
