Group 1: Current Market Dynamics - Currently, the primary solutions for humanoid robot joints are harmonic and planetary reducers, as they align well with the requirements for size, weight, precision, cost, and torque output [1]. - Harmonic reducers are compact with high transmission precision and low backlash, while planetary reducers offer strong torque and excellent power performance through multi-stage gear transmission [1]. Group 2: Technological Advancements - Cycloidal reducers are anticipated to fill the performance gaps of harmonic and planetary reducers through technological improvements, particularly in terms of precision and impact resistance [2]. - Companies like Hechuan Technology have achieved breakthroughs in core performance, expanding the rated torque coverage from 10 N·M to 140 N·M, with a fivefold rated overload capacity [2]. - Keda Li's subsidiary, Kemon, has introduced a lightweight cycloidal reducer that reduces weight by 73% compared to traditional models, addressing the impact resistance issues of harmonic reducers [2]. Group 3: Future Outlook - The humanoid robot joint transmission solutions are entering a phase of refined adaptation, with the potential for precise selection based on the force characteristics of different joints, thereby accelerating the commercialization of humanoid robots [3].
