Older adults’ initial perceptions of a quadruped robot during assisted walks in residential care: A qualitative pilot study

: Population ageing has increased interest in technologies that may support autonomy and engagement in later life. While social robotics research has largely focused on humanoid designs, limited evidence addresses how older adults perceive quadrupedal zoomorphic robots in care settings. This qualitative pilot study examines older adults’ initial perceptions of a quadruped robot (Unitree Go2) used during assisted walking sessions in a residential facility in Spain. The study involved seven long-term care home residents aged between 79 and 94. The participants completed three consecutive sessions (baseline observation, robot-assisted walk, and robot-assisted walk with conversational interaction). Semi-structured interviews were conducted one week later. Data were analysed through hybrid thematic coding combining deductive categories derived from the UTAUT framework and inductive theme development. Participants tended to describe the robot primarily as a practical walking aid and, in some cases, as a situational source of interaction during the activity. Positive evaluations coexisted with expressions of technological insecurity and limited prior exposure. The need for clear guidance, accessible design, and contextual human support emerged as relevant factors shaping experience. The findings reflect initial, context-specific interpretations derived from a brief interaction, rather than stable relational outcomes or established patterns of use. This exploratory study identifies considerations for the design and implementation of quadrupedal robots in residential care and contributes to ongoing discussions on older adults’ interactions with emerging robotic technologies.
