Rebel robot helps researchers understand human-machine cooperation

In a new twist on human-robot research, computer scientists at the University of Bristol have developed a handheld robot that first predicts then frustrates users by rebelling against their plans, thereby demonstrating an understanding of human intention. In an increasingly technological world, cooperation between humans and machines is an essential aspect of automation. This new research shows frustrating people on purpose is part of the process of developing robots that better cooperate with users. The team at Bristol have developed intelligent, handheld robots which complete tasks in collaboration with the user. In contrast to conventional power tools, that know nothing about the tasks they perform and are fully under the control of users, the handheld robot holds knowledge about the task and can help through guidance, fine-tuned motion and decisions about task sequences. While this helps fulfil tasks quicker and with higher accuracy, users can get irritated when the robot's decisions are not in line with their own plans. Latest research in this space by PhD candidate Janis Stolzenwald and Professor Walterio Mayol-Cuevas , from the University of Bristol's Department of Computer Science , explores the use of intelligent tools that can bias their decisions in response to the intention of users.
