在本文中，我们研究了多只大鼠相互作用时大鼠对机器大鼠的行为反应。实验是在一片开阔的田野上进行的，在那里，一只名为WR-5的机器鼠与三只实验鼠放在一起。WR-5正在跟踪一只大鼠(目标)，同时在互动过程中避开另外两只大鼠(外部观察者)。每只目标大鼠的行为特征是通过对其运动活动和进行饲养、身体梳理和骑马动作的频率进行评分来评估的。此外，还测量了被其他老鼠骑上的频率。实验结果表明，交互后目标变得更加活跃。行为特征更活跃的老鼠更容易被机器人调整。外部观察者在机器人附近花费的时间增加表明，即使没有直接的互动，仿生机器人也有可能调节老鼠的行为。因此，本研究为塑造群居动物的社会性提供了一种新的途径。
In this paper, we study the behavioral response of rats to a robotic rat during multi-rat interaction. Experiments are conducted in an open-field where a robotic rat called WR-5 is put together with three laboratory rats. WR-5 is following one rat (target), while avoiding the other two rats (outside observers) during interaction. The behavioral characteristics of each target rat is evaluated by scoring its locomotor activity and frequencies of performing rearing, body grooming and mounting actions. Additionally, the frequency of being mounted by other rats is also measured. Experimental results show that the target becomes more active after interaction. The rat species, with more active behavioral characteristics, is more susceptible to being adjusted by the robot. The increased time spent by the outside observers in the vicinity of the robot indicates that a biomimetic robot has the promise for modulating rat behavior even without direct interaction. Thus, this study provide a novel approach to shaping the sociality of animals living in groups.
