Robotic Fish
A Robotic Fish is an underwater robot designed to move through water like a real fish. Instead of conventional propellers, many robotic fish use a flexible tail, fins, and small motors or actuators to create swimming movements. Sensors can help the robot detect obstacles, measure water conditions, and maintain its direction and depth.
Robotic fish can be used for underwater research, environmental monitoring, marine observation, and inspection. They can collect information about water temperature, pollution, aquatic life, and underwater structures while moving quietly through the water. Their fish-like movement can also make them suitable for observing marine animals without causing excessive disturbance.
A robotic fish combines mechanical engineering, electronics, sensors, control systems, and robotics. A microcontroller can process sensor information and control the motors that move the tail and fins. More advanced systems can operate autonomously, follow predefined paths, avoid obstacles, and transmit collected data to researchers, making robotic fish an interesting example of bio-inspired robotics.
