The network visualisation shows a set of interconnected topics with different keywords. The central nodes, labelled artificial intelligence and service robot, are surrounded by related terms such as tourism, technology acceptance, customer experience, and robotics, forming a complex web of interconnected concepts. The visualisation uses varying colours to distinguish clusters of related terms and shows how these topics are linked across different research areas.Keyword network for robotic technology research (2012–2024)
