科学家们用一个叫"Wavy Dave"的机器人螃蟹来研究 男性小提琴手螃蟹在交配季节如何竞争。 Scientists used a robot crab named "Wavy Dave" to study how male fiddler crabs compete during mating season. 这个机器人旨在模仿雄蟹的大型爪子运动, 帮助研究人员理解螃蟹在竞争中的行为。 The robot, designed to mimic the large claw movements of male crabs, helped researchers understand the crabs' behavior in rivalry situations. 研究发现雄性螃蟹根据机器人爪的大小调整爪子的缩放, 而不一定要提高自己的挥手速度, 这表明当它们看到更大的对手时,它们可能更加谨慎。 The study found that male crabs adjust their claw-waving based on the size of the robot's claw and don't necessarily increase their own waving speed, suggesting they may be more cautious when they perceive larger rivals.
