Yuejia Lingdong (Shenzhen) Technology Co., Ltd. - 越甲灵动（深圳）科技有限公司

Yuejia Lingdong (Shenzhen) Technology Co., Ltd., which brands itself in English as Super-smart Robotics, is a Shenzhen-based high-tech enterprise focused on intelligent motion control and bio-inspired legged robots. The company describes itself as a fully self-developed, full-stack embodied-intelligence firm, with an engineering team drawn from robotics laboratories at Zhejiang University, Shanghai University and Tongji University, supplemented by veteran engineers recruited from Huawei and ZTE. According to the company, it has filed applications for more than 100 domestic and international patents, including over 20 invention patents, covering the core actuators used inside its own robots. Yuejia Lingdong states that it independently designs and manufactures the motors, reducers and controllers that go into its quadruped platforms, and says this in-house component strategy lowers unit production cost by roughly 40 percent compared with competitors that depend on third-party actuator suppliers. The company is headquartered on the 27th floor of Tower A, Building 2, Shenzhen Bay Innovation Technology Center, No. 3156 Keyuan South Road, Yuehai Sub-district, Nanshan District, Shenzhen, Guangdong.

The company's product line centers on the YJ30 family of quadruped robots. The base YJ30 model weighs 17.5 kilograms, carries a 10-kilogram payload, reaches a top speed of 3 meters per second, climbs steps up to 20 centimeters high, and is rated IP54, with runtime of about 1.5 to 2 hours on a single battery pack or up to 3 hours with an optional dual-battery configuration; it integrates Wi-Fi and 4G/5G connectivity along with live video transmission, voice recognition, person-following and autonomous-navigation functions. A reinforced YJ30 W variant raises weight to 20 kilograms, payload to 12 kilograms, top speed to 5 meters per second and step-climbing height to 60 centimeters. For heavier-duty tasks, the YJ30 Max scales up to 45 kilograms with a static payload of 50 kilograms and a dynamic payload of 30 kilograms, an IP67 ingress rating, roughly 3 to 4 hours of runtime, and the ability to climb 30-centimeter steps; the company lists this model for sale on its own site at approximately 288,000 yuan.

Yuejia Lingdong positions its quadruped line for power-grid inspection, police and security patrol, industrial and facility security inspection, and education or cultural-tourism demonstration scenarios. The company's published timeline of activities includes a cooperation with Shenzhen Metro announced alongside its debut at the China Hi-Tech Fair, a guide-dog robot demonstration timed to a Paralympic Games event, and a smart elder-care collaboration referencing a university partner, alongside participation in a Nanshan District enterprise showcase and a 2026 global AI conference for Chu-region entrepreneurs. The company maintains a service hotline and separate email addresses for sales, supply-chain and brand-partnership inquiries, and exhibited its patrol-robot lineup, together with a planned intelligent-inspection product launch event, at the 2026 World Robot Conference in Beijing under booth D402.
