Isolation wards operate in quarantine rooms to prevent cross-contamination caused by infectious diseases. Behind the benefits, medical personnel can have the infection risk from patients and the heavy workload due to the isolation. This work proposes a robot-assisted system to alleviate these problems in isolation wards. We conducted a survey about the medical staff's difficulties and envisioning robots. Using the investigation result, we devised three valuable services using two kinds of heterogeneous robots: telemedicine, emergency alert, and delivery services by care robots and delivery robots. Our system also provides user-interactive components such as a dashboard for medical staff and a patient app for inpatients. To manage the services efficiently, we suggest the robotic system based on a central control server and a hierarchical management architecture. Through a user study, we reviewed the usability of the developed system and its future directions.

To help people use their limited space efficiently, we propose an origami-based transformable robotic space called “PopupBot.” Specifically, we developed a robotic playhouse for children. A large origami structure with a bellows pattern is controlled by a servo motor and transforms into various types of furniture. For natural child-robotic space interaction, PopupBot perceives the child's intention for the space through speech recognition and provides appropriate space by inferring the space type matching the intention. We expect the PopupBot to provide a new space for people who suffer from staying in limited space especially due to the COVID-19 pandemic.
