Recorded health checks
Rhem reads blood pressure, heart rate, and blood oxygen (SpO₂), then keeps readings in a dated history so earlier results can be reviewed over time.
Rhem
Rhem is a tabletop AI companion robot for older adults and their families, combining voice interaction, recorded blood pressure, heart rate and blood oxygen readings, reminders, and shared updates. Its camera-free Halo accessory adds room-based fall detection without requiring the user to wear a device.
Rhem at a glance
Rhem is a tabletop AI companion robot designed for home use by older adults and the family members who help keep track of their routines and wellbeing. It combines voice interaction, recorded health checks, reminders, conversation history, and family-facing updates in one system.
The robot records blood pressure, heart rate, and blood oxygen readings in a dated history; provides plain-language answers and follow-up conversations; and can use AI agents to browse websites or make phone calls for practical tasks. A shared view gives family members a way to review available updates and requests over time. Rhem also supports Halo, a camera-free, non-wearable fall-detection accessory for room-based monitoring.
Core features
Conversation pattern history
The robot compares recorded conversation patterns, including recurring topics and changes across exchanges, to give families additional context for follow-up conversations. The site presents these cues as context, not a cognitive diagnosis.
Everyday context
Rhem brings readings, conversations, and routines into a shared view, helping families compare recent activity with a person’s own earlier history.
Voice interaction
Users can ask about food, sleep, activity, recipes, weather, and other everyday topics and continue with follow-up questions in plain language.
Task assistance
Rhem’s AI agents can browse websites and make phone calls for tasks such as booking appointments, calling a pharmacy, and ordering essentials.
Camera-free fall detection
The camera-free Halo accessory adds non-wearable fall detection in a selected room. Coverage depends on placement, ceiling or wall position, room shape, and whether the person’s whole body is inside the detection area.
Practical use cases
Routine wellness check-ins
A parent can place a finger on Rhem’s sensor for a health check and revisit dated readings later, rather than relying on memory or a single measurement.
Remote family follow-up
A family member can review available readings, routines, conversation patterns, and requests in the shared family view to decide what merits a follow-up conversation.
Everyday companionship and questions
A user can ask Rhem about a recipe, weather, sleep, activity, or another everyday question and continue the exchange by voice.
Assistance with recurring errands
A user can ask Rhem to handle practical errands such as calling a pharmacy, booking an appointment, or ordering essentials through its AI agents.
Room-based safety monitoring
A household can place Halo in a selected room to add camera-free fall detection without requiring the monitored person to wear or press a device. Additional Halos can extend monitoring to other rooms, subject to coverage limits.
Pros and Cons
Pros
- Combines health readings, routines, conversations, reminders, and family updates in one home device.
- Stores readings in a dated history instead of presenting only a one-time result.
- Supports practical voice-led tasks, including website browsing and phone calls through AI agents.
- Halo provides camera-free, non-wearable fall detection and one Halo is included with each Rhem.
- Offers Cloud and Local configurations to reflect different preferences for where Rhem’s core AI runs.
Cons
- Rhem needs power and Wi-Fi for home operation; Halo additionally requires a Rhem robot and 2.4 GHz Wi-Fi.
- Health and conversation examples on the site are not medical assessments or diagnoses, and the help-request demonstration is not a guarantee that assistance will arrive.
- Fall-detection coverage is room- and placement-dependent, with walls, furniture, ceiling height, and room shape affecting the monitored area.
FAQ
What is Rhem?
Rhem is a tabletop home robot for health check-ins, reminders, voice conversations, family updates, and tasks such as browsing websites or making phone calls through its AI agents.
What are the Cloud and Local options?
Rhem requires power and Wi-Fi. The order page offers Cloud and Local configurations: Cloud uses cloud-based AI, while Local is intended for customers who prefer Rhem’s core AI to run on the device.
How does Halo work with Rhem?
One Halo is included with Rhem. Halo requires a Rhem robot and 2.4 GHz Wi-Fi, and cannot be used independently. Additional Halos are intended for rooms that need separate monitoring coverage.
Can Rhem replace emergency services?
Rhem’s help-request demonstration shows an attempted call to a family contact, not confirmation that help has arrived. The site explicitly says not to rely on Rhem for emergencies and to contact emergency services directly.
