How does the Bionic Robot Fish in West Lake communicate with the shore?

The bionic robot fish mainly uses a hybrid communication mode (underwater acoustic communication + short-range radio communication) to maintain contact with the shore or mother ship:

1. Underwater Acoustic Communication (Primary Method)

Electromagnetic waves attenuate rapidly underwater, so sound waves are mainly used for signal transmission. The robot fish is equipped with an underwater acoustic modem, which transmits video, sensor data, and position information to buoys or shore-based base stations via sound waves of specific frequencies (usually 20–50 kHz). The delay generally ranges from hundreds of milliseconds to several seconds, which is greatly affected by water quality and distance.

2. Radio Communication (Auxiliary/Near-Surface Method)

When the robot fish is close to the water surface, it extends a small waterproof antenna and communicates directly with the control center using the 2.4 GHz or 5.8 GHz frequency band. This method offers high data transmission rates, making it suitable for transmitting high-definition images at high speed, but it is basically unavailable in deep-water environments.

3. Communication Relay

In some designs, fixed underwater acoustic nodes or floating communication buoys are deployed in West Lake to form a small communication network, ensuring the robot fish maintains stable connectivity even in long-distance or complex water areas.
