Summary
Amphibious Spherical Robots (ASRs) use electric fields for underwater communication and collaboration. This study introduces a formation strategy for turtle-inspired ASRs to navigate complex environments using dynamic visual servoing and adaptive control.
Area of Science:
- Robotics
- Artificial Intelligence
- Marine Engineering
Background:
- Traditional communication methods fail in turbid underwater environments.
- Amphibious Spherical Robots (ASRs) offer a solution for confined aquatic spaces.
- Turtle-inspired designs provide a model for cooperative multi-robot systems.
Purpose of the Study:
- To propose an embedded architecture formation strategy for ASRs.
- To enable long-distance path following using dynamic visual servoing.
- To enhance underwater robot communication and collaboration.
Main Methods:
- Designing an artificial multi-robot cooperative mode.
- Implementing electronic communication and collaboration devices.
- Developing adaptive visual servoing controllers for trajectory tracking.
- Utilizing a centralized optimization algorithm for mission changes.
Main Results:
- The leader robot effectively controls group motion along a geometric path.
- The system maintains communication efficiency and timely arrivals.
- Adaptive controllers successfully handle system dynamics and environmental interactions.
- The proposed control strategies ensure stable group formation and target achievement.
Conclusions:
- The developed strategy enables robust cooperative navigation for ASRs in challenging underwater conditions.
- Electric field communication proves effective where other modalities fail.
- The turtle-inspired approach enhances multi-robot coordination and mission success.

Buoyancy and Stability for Submerged and Floating Bodies
2.4K
In fluid mechanics, buoyancy and stability are key concepts for understanding the behavior of submerged and floating bodies. When a stationary body is fully or partially submerged in a fluid, the fluid exerts a force on the body known as the buoyant force. This force acts vertically upward through a point called the center of buoyancy, which is the center of the displaced fluid volume. According to Archimedes' principle, the magnitude of the buoyant force is equal to the weight of the fluid...

Robbers Cave

During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...
