High Mobility
Adopting a three joint swing design, inspired by the swimming mechanism of fish. The precise three joints enable the robotic fish to navigate complex underwater environments with ease, effortlessly handling narrow slits, obstacles, precise positioning, and exploration tasks, demonstrating excellent performance.
Floating Adjustment
By adjusting the center of gravity and buoyancy of the internal mechanical structure, biomimetic fish can achieve sinking or floating. Moving the center of gravity component can increase the sinking force, while adjusting the center of gravity position to move the floating center upward can use buoyancy to make it rise.
Open Source Code
The robotic fish has excellent performance and is equipped with multiple interfaces to support secondary development. Whether it is improving control accuracy or expanding application scenarios, these interfaces can meet the needs and provide infinite possibilities.
Designer and manufacturer of mobile robots, shipped to over 50 countries worldwide
BIOMIMETIC SHARK DESIGN
Taking the deep-sea dominant shark as a reference, adopting a shark shaped design. This endows the bionic robotic fish with an elegant appearance, reduces resistance during movement, and enables the bionic robotic fish to perform tasks more quickly and agilely.
BIOMIMETIC FISH SWARM CONTROL
Each bionic fish has intelligent decision-making ability, adjusting its position and speed based on instructions and environmental information. Under cluster control, they automatically coordinate and maintain overall consistency based on the surrounding environment and the status of other members.
BIOMIMETIC FISH ROBOT CLUSTER FORMATION SYSTEM
The biomimetic robotic fish swarm formation system utilizes optical positioning technology to support multiple positioning systems and cluster communication. By using a unified control interface, the swarm formation and collaborative control of biomimetic robotic fish can be achieved, ensuring that they move along the planned route.
Overall Design Framework
The system consists of a ground station, wireless transmitter, camera, pool, and robotic fish. PC analyzes camera images, plans paths based on different situations, and returns control strategies to the robotic fish through serial ports and wireless modules.
Cluster Collaboration System
The system includes a positioning system, cluster control unit, communication equipment, and bionic robotic fish. The positioning system provides information, the control unit sends instructions, the robotic fish executes tasks, and the communication equipment ensures smooth information flow, achieving efficient collaboration.
BIOMIMETIC FISH ROBOT CLUSTER FORMATION SYSTEM HIGHLIGHTS
Collaborative Decision Making
By controlling algorithms and communication technology, information sharing between biomimetic fish can be achieved. Based on shared information, simulated fish can collaborate to make decisions to adapt to environmental changes and task requirements.
Distributed Control
Each bionic fish has the ability to make autonomous decisions without relying entirely on a central control unit. This enables fish schools to quickly adjust their formation and travel strategies in complex waters, demonstrating a high degree of flexibility and adaptability.
Task Allocation
The cluster adjusts its formation and task allocation in real-time based on tasks and environmental changes, avoiding resource waste and repetitive labor, improving efficiency, optimizing resource utilization, and ensuring optimal performance and coordination in changing environments.
