According to a research report, core robot components account for over 50% of the total machine cost, making them key to performance and cost. Technical pathways are becoming clearer, and the industry is approaching the eve of mass production. Industrialization is accelerating, with core components being the critical track determining overall machine performance, cost, and value. These components have barriers in processes and production capacity. Leading suppliers with technological and mass production advantages are expected to capture high market share and achieve high ASP and profit premiums. In the short term, prioritize harmonic/planetary reducers, lead screws, and motors with mature technology and high certainty for mass production. In the medium to long term, focus on opportunities for new reducer iterations, while actively investing in the dexterous hand track as technology matures and value potential becomes prominent. Also, pay attention to lightweight products and targets related to cutting-edge motor technologies. The main views are as follows: Reducers: Harmonic reducers (light-load precision, compact size, suitable for small arms and wrists) and planetary reducers (controllable cost, mature processes, suitable for elbows and shoulders) are mainstream in China. Cycloidal pinwheel reducers (high load, high rigidity, large torque range, suitable for hips and waist) are a new direction for high-torque joints. Lead Screws: Ball screws focus on cost-effectiveness and are suitable for light-load positioning. Planetary roller screws have 3-6 times the load capacity and 10-15 times the lifespan of ball screws, making them core components for high-load joints such as thighs and large arms. Motors: Focus on high power density and lightweight design. Hollow cup motors (low inertia) and frameless torque motors (high torque) are mainstream. Axial flux motors (efficiency over 96%) represent the cutting edge but require breakthroughs in heat dissipation and cost. Dexterous Hands: Technical pathways have not yet converged (motor + linkage/direct drive/tendon drive). Mainstream products offer 12-22 degrees of freedom, with the core challenge being balancing high degrees of freedom, lightweight design, and cost. Sensors: Force control and tactile sensing are core technologies. Current loop force control is low-cost, while six-dimensional force sensors offer high precision (0.5% FS and above), making them key for high-precision operations. Tactile sensing is evolving toward array-based and multi-modal integration. Lightweighting: Achieved through structural optimization, material substitution (magnesium alloy, PEEK), and process innovation, it is key to overcoming endurance and performance bottlenecks. Leading companies like Unitree G1 and Zhiyuan Lingxi X2 have reduced weight to 35kg. Risks include slower-than-expected technological progress, delays in industrialization, and intensifying competition.
