ZeroErr

A Shenzhen maker of robot joint modules, focused on standardized, integrated eRob joints.

ZeroErr was founded in Shenzhen in 2016 by Xiqing Jia. It builds robot joint modules — integrated units combining a motor, gearbox, encoder, and driver — with its eRob series used in collaborative robots, medical robots, automation equipment, and humanoid robots. Its founder's philosophy is “fake customization, real standardization”: most of what customers call custom requirements really just means lighter, smaller, stronger, or cheaper, needs that can be met by iterating on a standard product. As humanoid robots move toward mass production, joint-supply capacity has become a bottleneck, drawing investor attention to upstream component makers like this one. In July 2026 it closed a Series C++ round of several hundred million RMB, led by Vertex Ventures and joined by Guotai Junan Innovation Investment, with existing investor Huakong Fund adding to its stake; the funds go toward expanding capacity and overseas markets.

ExampleA small collaborative-arm team can buy six eRob joint modules and assemble them directly into a 6-axis robot arm, without designing its own motors and gearboxes.
