Can China’s Explosion-Proof Robotic Dog Joint Modules Be Mass-Produced? HONPINE Has Fully Achieved It

Jun 12, 2026

Recently, HONPINE’s independently developed explosion-proof joint modules secured orders worth tens of millions of RMB, marking the official large-scale commercialization of China’s explosion-proof robotic joints. These joint modules have been successfully integrated into multiple quadruped robot (robotic dog) platforms and deployed in high-risk environments such as petrochemical facilities, natural gas inspection sites, and emergency rescue operations—areas that previously relied heavily on manual labor or imported components.


What Makes HONPINE Explosion-Proof Joint Modules Different from Conventional Joint Modules?


Unlike the industry-standard approach of using off-the-shelf motors followed by secondary explosion-proof modifications, HONPINE possesses full-stack R&D capabilities covering explosion-proof servo motors, joint modules, and complete robot integration.


With industry-leading expertise in explosion-proof structural design and certification, HONPINE provides comprehensive explosion-proof solutions that integrate motors, drives, and sensors into a single system. This capability has helped numerous robotics companies significantly shorten the certification cycle for their robotic platforms.


Today, quadruped robots equipped with HONPINE explosion-proof joints are already performing routine inspection tasks in several national-level chemical industrial parks. HONPINE will continue to advance its joint technologies, enabling more specialized robots to operate in environments where humans cannot safely approach or perform tasks, while supporting the safety upgrade of China’s intelligent equipment industry.


What Applications Are HONPINE Explosion-Proof Joint Modules Suitable For?


The product series includes three major categories of explosion-proof joints:


  • Knee joints

  • Pitch joints

  • Roll (side-swing) joints


Key performance specifications include:


  • Peak torque: 450 N·m

  • Rated torque: 110 N·m

  • Supports continuous operation with robot payloads exceeding 20 kg


These explosion-proof joint modules have been successfully integrated into multiple quadruped robot platforms and deployed in hazardous environments such as petrochemical plants, natural gas inspection facilities, and emergency rescue operations. The technology fills a critical gap in China’s domestic robotics industry and reduces dependence on imported solutions for high-risk applications.
