Hinge: a responsive social robot can provide repeatable short engagement sessions as an adjunct to care, without replacing clinical assessment or human relationships.
Collections: Human still decides · Embodied work
Executive brief
A humane robotics case should report comparator-sensitive and null findings, not only engagement gains.
AI value · Observed visual and verbal engagement
VerifiedPARO participants were significantly more verbally and visually engaged than plush-toy participants.
Engagement effects do not establish broad clinical improvement.
Before
Provides usual care and available psychosocial activities. → Observes mood, engagement, and agitation.
After
Participates in an individual non-facilitated 15-minute responsive-robot session three times weekly. → Interprets response and adjusts care; stops use if distress or infection-control concerns arise.
Human boundary
Care staff and clinicians decide suitability, continuation, and treatment.

Work that left the path
Human role before
Staff delivered and observed psychosocial support.
Human role after
Staff select appropriate residents, monitor response, and integrate a robotic adjunct into care.
AI role
Decision mode: responsive therapeutic interaction. PARO reacts to touch and voice; it does not diagnose or prescribe.
Look-alike plush-toy sessions.PARO participants were significantly more verbally and visually engaged than plush-toy participants.
Ten-week cluster-randomized intervention with follow-up. · 415 residents across 28 facilities.
Engagement effects do not establish broad clinical improvement.
Usual care and plush-toy comparison.Video observation favored PARO over usual care, but CMAI-SF showed no significant group difference and PARO was not consistently superior to plush toy.
Ten-week intervention. · 415 residents.
Mixed outcome measures make this a qualified, not uniformly positive, case.
Anti-pattern
Using a social robot to reduce human contact or overstating mixed agitation results.
