For the first time, China has successfully launched a domestically developed robotic arm capable of performing seven distinct functions in deep-sea environments, aimed at enhancing the exploitation of offshore oil and natural gas resources.
According to Xinhua News Agency, the announcement was made by Beijing’s Offshore Oil Engineering Co., Ltd., which developed the arm. The robotic device was installed on a remotely operated vehicle (ROV) and successfully completed a series of complex tasks during its initial deployment in the Pearl River Estuary in southern China. It is capable of operating at depths of up to 7,000 meters.
The arm demonstrated seven core capabilities—extension, retraction, swinging, rotating, opening, grasping, and clamping. During the mission, it efficiently performed tasks such as valve operation and equipment installation in strong underwater currents.
Weighing just 60 kilograms—35% lighter than foreign alternatives—the arm is also designed for high performance, capable of lifting up to 125 kilograms at full extension. Additionally, it is 40% more cost-effective than imported models.
The company noted that the successful deployment of this robotic arm marks a significant technological breakthrough and elevates China into an elite group of nations capable of developing advanced deep-sea robotics.
