A Social Robot Learning to Facilitate an Assistive Group-Based Activity from Non-expert Caregivers

Socially assistive robots are a promising technology for supporting residential care facilities to provide stimulating recreational activities to residents in group settings. In order for caregivers to teach robots customized recreational activities for residents in their facilities, these robots need to be able to learn such activities from non-experts. In this work, we present a novel learning from demonstration system that allows socially assistive robots to learn customized group recreational activities from caregivers and facilitate these activities with users. We validate the usability and effectiveness of the proposed system by conducting a robot teaching study with caregivers and the Tangy robot at a local residential care facility. The caregivers found the learning system easy to use, experienced moderately low perceived workload, and were able to successfully teach Tangy the game of Bingo. Once Tangy learned the game, it autonomously facilitated Bingo games with elderly residents. The residents found the robot behaviors, personalized by the caregivers, both helpful and entertaining. Furthermore, they enjoyed playing Bingo with Tangy and would participate in future games.
