HONPINE Robot Joint Motors Supplier

During the development and integration of humanoid robots, the compatibility of communication protocols in robot joint actuator directly impacts the control accuracy, system stability, and flexibility for future expansions. Recently, we’ve received several inquiries from engineers asking whether our robot's core hardware harmonic robot rotary actuator can simultaneously support both EtherCAT and CAN protocols. What are the functional differences between these two connection methods? Let’s take a deep dive into these questions today

As the robotics industry continues to evolve at high speed, the robot joint actuator, known as the “power core” of robots, directly determines a machine’s motion precision, load capacity, and application range.Leveraging the unique benefits of harmonic drive technology, it has become the preferred solution for high-end robotic joints.

Bionic robots are the driving engine of high-end equipment manufacturing, helping humanity progress from manufacturing intelligence to understanding intelligence.They require high-precision joint modules, intelligent sensing devices, and high-performance control chips and algorithms working synergistically.A typical bionic humanoid robot features 10–40 degrees of freedom. Modular harmonic joint modules simplify system integration, improve reliability, and enhance maintainability.

The robot joint module is the core hardware of humanoid robots, currently mainly divided into two major categories: rotary and linear. In humanoid robot designs, the choice often involves trade-offs based on the application scenario and manufacturing cost.

At present, more than 90% of robot joint modules on the market adopt harmonic drives or planetary reducers. The cycloidal reducer, however, is just beginning to be tested in humanoid robot joints in China and has not yet been fully validated by the market.

With the continuous development of robotics, servo control systems are playing an increasingly important role in complex working environments. A coordinated control strategy combining servo motors and harmonic drives improves the system’s dynamic performance and control accuracy. The Harmonic Drive + Servo Motor pairing is the core solution for achieving miniaturization, lightweight design, and high precision in industrial and collaborative robots.

In the operation of robotic harmonic drive motors, the communication protocol serves as a critical link ensuring stable collaboration among core hardware components. EtherCAT and CAN are the two mainstream choices, with significant differences in performance that directly impact the control precision and response efficiency of harmonic drive motors.

HONPINE harmonic drive servo motors achieve ultra-high performance and precision through a modular framework that integrates high-precision harmonic drives, high-accuracy optical encoders, and high-power-density motors. Professional testing with laser interferometers ensures stable, accurate, and predictable execution of position commands, meeting the stringent requirements of high-end industrial applications for precise motion.
