Abstract: “We research on autonomous mobile robots with a seamless integration of perception, cognition, and action. In this talk, I will first introduce our CoBot service robots and their novel localization and symbiotic autonomy, which enable them to consistently move in our buildings, now for more than 1,000km. I will then introduce multiple human-robot interaction contributions, and detail the use and planning for language-based complex commands, and robot learning from instruction and correction. I will conclude with the robot explanation generation to reply to language-based requests about their autonomous experience. The work reported is joint with my students and collaborators in the CORAL research group.”
