About
About ZeroErr (零差云控)
ZeroErr’s eRob modules integrate a motor, reduction mechanism, bearings, encoder and control components into compact rotary joints. I-series and T-series configurations cover different diameters, torque ranges and mechanical layouts, allowing robot manufacturers to build arms and humanoid joints from standardised motion modules rather than engineering each axis independently.
The eCoder range provides absolute magnetic position feedback in several package sizes, including hollow-shaft arrangements for routing cables through a joint. ZeroErr supplies product selection, development documentation and application support to collaborative, surgical, humanoid and industrial-automation programmes. The actuator and encoder families can be used together or integrated separately into a customer’s existing drive architecture.
