Robot Crab 'Wavy Dave' Demonstrates Claw-Waving Battle Strategies
Scientists developed a biomimetic robot crab named Wavy Dave to study how male fiddler crabs respond to competition, revealing that crabs wave longer when they see a rival, indicating behavioral adjustments in competitive signaling. The robot's interactions showed crabs' complex responses, including aggression and altered waving behavior, providing insights into animal social dynamics.
