Designed to replicate the physical attributes and movements of a real whale shark, this robotic version can float, swim, dive, and even perform mouth movements with high accuracy. The robot weighs approximately 771 pounds (350 kilograms) and features seven drive joints, controlled by complex computing, communication, and sensing technologies.

The robotic shark is equipped with capabilities such as wireless remote control, programmable swimming patterns, and multi-joint bionic propulsion. It can reach a maximum speed of 0.7 meters per second and dive to depths of 20 meters. Its onboard systems include optical cameras, sensors, sonar, and Beidou positioning, enabling it to conduct tasks like water quality monitoring, underwater mapping, and potentially, military operations.

Deputy Director of the Underwater Propulsion Technology Research Office, highlighted the challenges in integrating sensor data to create a responsive system for the robot. This involved processing large amounts of data from various sensors to ensure precise navigation and obstacle avoidance.

The robotic whale shark employs a propulsion system designed to reduce environmental impact compared to traditional underwater robots, which typically use propellers. Its enclosed and streamlined design minimizes the risk of entanglement with underwater obstacles.

Following the whale shark’s development, Shenyang Aerospace Xinguang Group has expanded its range of bionic marine robots, including models based on other aquatic species.
