In the last years, museums around the world began using museum guide robots as an alternative to audio guides. Thus, it is important to identify how these new museum guides can optimally interact with visitors and whether they are more efficient that conventional audio guides. In this paper, we present the results from an experimental study which compared conventional audio guides with robots with different ‘personality’. These results demonstrate that people remember significantly more information when they are guided by a cheerful robot than when their guide is a serious one or a conventional audio system. Importantly, we also introduce the idea of two collaborative tour guide robots. This idea was inspired by cognitive studies showing that people remember more when they receive information from two different human speakers. Interestingly, our participants also liked more our collaborative robots, than any version of a single robot and/or audio system.

在过去的几年中，世界各地的博物馆开始使用博物馆指南机器人来代替音频指南。因此，重要的是要确定这些新的博物馆指南如何与游客进行最佳互动，以及它们是否比传统的语音指南更有效。在本文中，我们介绍了一项实验研究的结果，该实验将传统的音频指南与具有不同“个性”的机器人进行了比较。这些结果表明，当人们用开朗的机器人引导时，与使用严肃的指南或常规音频系统相比，人们能记住的信息要多得多。重要的是，我们还介绍了两个协作式导游机器人的想法。这个想法的灵感来自认知研究，表明人们从两个不同的人类说话者那里收到信息时会记住更多。有趣的是
