siamese fighting fish eatWhen the fish replica emitted its full sequence of cues, the depth of aggression handed even that produced by real fish opponents. Fish reproduction shape was necessary for conspecific opponent belief, evoking big aggressive responses. Overall, this study highlights that the efficacy of an artificial opponent eliciting competitive behaviour in fish can be boosted by exposure to distinct signals. Optimizing the cue mixture brought by the robot fish replica may be positive to predict escalating levels of aggression. The use of robotics to establish biomimetic social interactions among animals and robots is a fascinating medical field, regarding both biologists and engineers. This fairly new analysis context investigates animal talents, providing novel approaches to design robots with better bendy and adaptive behaviours in unstructured environments1, 2.
