Chatbots, voice assistants, and robots – both programmable machines and social robots – had been used in learning for decades. At the GROUND 2025 Workshop on 30 June 2025, held as part of the IAS 2025 in Genoa, Italy, Prof. Dr. Oliver Bendel from the FHNW School of Business in Switzerland presented his own projects from the past 15 years. Some of his chatbots and voice assistants, such as GOODBOT, BESTBOT, and SPACE THEA, recognized user problems and responded appropriately. They demonstrated empathy and emotion. Pepper had been used as an educational application for children with diabetes, and Alpha Mini served as an educational tool in elementary schools. Chatbots for dead, endangered, and extinct languages such as @ve, @llegra, and kAIxo were designed to be integrated into learning environments for all age groups. In recent years, the technology philosopher and information systems expert primarily used GPT-based systems such as Social Robotics Girl and Digital Ethics Girl in his courses. These systems were capable of receiving and answering questions from multiple students simultaneously, even when the questions were asked in different languages. Thanks to prompt engineering and retrieval-augmented generation (RAG), they became specialists in their respective domains. In his keynote „Robots, chatbots, and voice assistants in the classroom“, Oliver Bendel asked how chatbots, voice assistants, and social robots would be designed as adaptive systems for multi-user settings in the future. These capabilities were considered especially important in classroom environments.
