We conducted a study with 16 healthy older adults to investigate their acceptance of robots for partner dance-based exercise. Participants successfully led a human-scale wheeled robot with arms (i.e., a mobile manipulator) in a simple forward/backward walking dance step, which we refer to as the Partnered Stepping Task (PST). The study contains relevant biomechanics data as mat files, questionnaire responses as excel files, and related code used to run the study
