Robot Dogs with Planetary Joint Motors Performed Well in China's 93rd Victory Day
On September 3, 2025, China held a large-scale military parade for 93rd victory day, during which it showcased the "Mechanical Wolf," a robotic dog belonging to the Army's unmanned combat unit. The HONPINE planetary joint motor perfectly matches the joint requirements of robot dogs.
Why Robot Dogs Are Suitable for Planetary Joint Motors
Robot dogs need to perform actions such as running, jumping, and climbing stairs. Therefore, the joint motor must provide immense torque instantly to accelerate and support the body, requiring extremely high torque density. Planetary joint motors are well-suited for this.
Robot dogs need to generate sufficient power within extremely limited space. Planetary joint motors integrate components such as motors, encoders, planetary reducers, and drivers, significantly saving space and reducing weight.
Robot dogs require precise foot trajectory planning and complex force-control interactions. The HONPINE planetary joint motor uses high-precision encoders to provide accurate motor rotor position and speed feedback. Its integrated design reduces control latency.
Robot dogs need to accomplish long-term missions, requiring longer lifespan. Planetary gears use metal gears with rolling contact, which wear slowly, offer a longer design lifespan, and are easier to maintain.
Planetary Joint Motor vs. Harmonic Joint Motor: Which Is More Suitable for Robot Dogs?
The main advantages of harmonic joint motors are zero backlash and ultra-high single-stage reduction ratios, making them more suitable for applications requiring high absolute positioning accuracy, such as medical machinery, CNC machine tools, and optical design. In contrast, planetary joint motors offer higher rigidity and impact resistance, making them more suitable for robot dogs.
Planetary Joint Motors Boost Future Army Development
It is conceivable that future military parades may feature mechanical dog units and humanoid robot units. The HONPINE planetary joint motor is particularly suitable for robot dogs. The HONPINE planetary joint module has a rated power of 1,686W and a rated torque of 100Nm. It is lightweight, supports the CAN communication protocol, and offers high waterproofness, making it adaptable to various combat needs.
Planetary joint motors, with their high torque density, high rigidity, impact resistance, and compact integration, are poised to transform the future alongside advanced robot dogs and humanoid robots.

Robot Joint Motors Empower Robots with Flexible Movement in Multiple Degrees of FreedomRobot Joint motors can be freely combined to form multi-degree-of-freedom (DOF) robotic arms and serve as the internal framework for service robots, breaking the industry's conventional product design paradigms. They not only meet performance requirements but also foster innovation within the sector. For instance, the smallest models can be applied in gimbals and drones, while the largest models are suitable for humanoid robots and robotic arms. Applications span industrial robots, civilian service robots, specialized robots, machining industries, precision instruments, transportation vehicles, and medical equipment.- How High-Precision Reducers Drive the Development of Intelligent Manufacturing TechnologyPrecision reducers are key enablers in intelligent manufacturing, providing the critical link between digital algorithms and physical motion. They ensure high-accuracy positioning in laser/visual navigation systems, enable precise wheel control in mobile robots, and guarantee repeatable motion in robotic arms. Their near-zero backlash characteristics allow manufacturers to achieve unprecedented levels of automation precision and reliability.
Trends in Humanoid Robotics from WAIC 2025: High Torque Micromotors for Robotic Joints Become MainstreamAt the 2025 World Artificial Intelligence Conference (WAIC), official data showed over 150 humanoid robots were exhibited simultaneously, with numerous manufacturers showcasing their products' comprehensive capabilities and latest achievements. The exhibition demonstrated significant expansion in humanoid robots' application scenarios, with major exhibitors presenting cutting-edge research outcomes and remarkably rapid technological iterations. Compared to last year, this year's robots are more lightweight, precise, and dynamic, with increasing adoption of high-torque micro motors in robotic joints.- Harmonic Reducer Enables Industrial Humanoid Robot Walker S2 to Achieve Autonomous Battery Replacement for 24/7 OperationWithout requiring manual intervention or shutdown, the humanoid robot can autonomously replace its battery in just 3 minutes. UBTECH Robotics, headquartered in Beijing Economic-Technological Development Area, recently announced exciting news: its new-generation industrial humanoid robot Walker S2 incorporates the world's first hot-swap autonomous battery replacement system for humanoid robots. This breakthrough technology endows Walker S2 with 24/7 continuous operation capability, establishing the foundation for smart manufacturing to achieve "non-stop next-generation productivity." The harmonic reducer's high reduction ratio, zero backlash, exceptional precision, high torque density, and lightweight design make it the optimal choice for joints in comparable industrial robots.
- HONPINE keeps up with the era of Industry 5.0 and better serves human-machine collaboration through precision transmission technologyThe concept of Industry 4.0, which corresponds to Industry 5.0, first appeared in Germany. In short, Industry 4.0 is to promote industrial transformation through information technology. It is an intelligent industrial era based on the Internet of Things, big data, artificial intelligence, etc. 5G technology, known as the "new engine of digital economy", is a product that closely fits the core concept of Industry 4.0 and is recognized by the world.
- Kawasaki Heavy Industries Launches the CORLEO Robot Horse: Harmonic Reducers Play a Key RoleKawasaki Heavy Industries has introduced the CORLEO, a highly agile robotic horse capable of traversing water, jumping, running, and striking dynamic poses. Designed to conquer challenging terrain, CORLEO's leg movement system features independently driven units for each limb, delivering exceptional stability and shock absorption. Its hind legs operate independently from the front, enabling smooth navigation over rough surfaces while maintaining the rider’s balance—even on stairs or uneven ground.
