Leaderdrive supplies harmonic drives to an estimated 60%–70% of humanoid manufacturers and is forming a China-based venture with SKF for humanoid robot transmission components.
Darker bar: ahead of the other company on that measure.
Leaderdrive is China's harmonic-reducer volume leader (STAR-listed) with 2025 revenue of RMB 570.7M (~$79M, +47%) and net profit of RMB 124.4M (more than doubled), pricing aggressively against Harmonic Drive Systems. It is the price-disruption side of the reducer duopoly-in-formation, with capacity of 790,000 reducers a year (plus a new project adding 1M more), a 30-40% Chinese harmonic share per J.P. Morgan, and customers across the Agibot, UBTech, and Tesla Optimus supply chains. Its industrial and humanoid joint demand is the driver.

Quanzhibo manufactures integrated precision joint modules, the actuators that drive humanoid and embodied-intelligence robots.
Darker bar: ahead of the other company on that measure.
Quanzhibo (泉智博) makes integrated joint modules for humanoid and general robots, and the shipment numbers are the reason it scores as highly as it does on deployment and production. In the first half of 2026 cumulative shipments of integrated joint modules passed 120,000 units, with over 60,000 shipped in June alone, the steepest ramp of any component maker in this registry. FY2025 orders exceeded RMB 150 million and 2026 orders are expected to reach several hundred million RMB. In April 2026 its precision joint production base in Wuxi entered production with a planned annual capacity at the million-unit level: an automation rate above 85 percent, a 90-second cycle time per joint module, first-pass qualification stable above 96 percent and product yield at 98 percent. Those are manufacturing figures rather than prototype claims, which is unusual in this segment and is why production scores 5. The investor base is the other signal: Hillhouse and Agibot both backed the company, putting Agibot on the cap table of both this row and Critical Point. Named customers are Leju Robotics, Songyan Dynamics and Galaxea. The company is splitting its footprint by function, keeping Wuxi as the manufacturing base while investing in Beijing and Shenzhen for research and embodied AI commercialisation and in Chongqing for large-scale high-end manufacturing and delivery stability.
