Medical Robots
“Hospital robot” sounds like one product. Hospitals use several, and they are not interchangeable. One is a surgical platform. One fetches supplies. One is a therapeutic companion. Buying, deploying, or even just understanding them starts with that split.
This is an educational guide for patients, families, and staff who keep seeing the same three names — da Vinci, Moxi, and PARO — used as if they were cousins. They share a building. They do not share a job. None of them is a consumer gadget you add to a home shopping basket the way you add a vacuum.
ⓘ Quick Answer
da Vinci is a surgeon-controlled system for selected minimally invasive operations. Moxi is a mobile hospital assistant that moves supplies, samples, and equipment so clinical staff walk less. PARO is a therapeutic seal robot used for comfort and engagement, including dementia care. They do not replace surgeons, nurses, or human company, and they are procured through clinical and organisational channels, not a weekend checkout.
Three jobs inside one hospital
Operate
da Vinci extends a surgeon’s hands and view. The clinician remains responsible for the procedure.
Fetch and carry
Moxi takes routine logistics off the clinical team: meds, labs, linens, equipment between units.
Comfort
PARO offers structured tactile and social interaction. No navigation, no lifting, no clinical decisions.
Not in this trio
Pharmacy automation, rehab exoskeletons, and disinfection robots are other medical categories. Do not collapse them into these three names.
da Vinci: surgical robotics, not an autonomous surgeon
The da Vinci Surgical System, from Intuitive Surgical, is used in hospitals and surgical centres for selected minimally invasive procedures. The surgeon sits at a console and controls robotic arms, with high-definition 3D visualisation. The system does not decide to operate and it does not replace the surgical team.
What it changes is access and control for procedures the hospital has already decided to perform this way. What it does not change is the need for trained staff, an operating room, anaesthesia, sterilisation, and a maintenance programme. Capital cost is quoted, not picked from a consumer shelf. If you are a patient, the useful questions are for your surgeon and hospital: is this approach appropriate for your case, who is operating, and what are the alternatives.
If you are a hospital evaluating a programme, you are buying a service line: training, utilisation, servicing, and room layout. Compare it with other surgical platforms on clinical fit, not on whether the robot looks advanced in a corridor photo.
⚠ Important
This article does not recommend any procedure. Surgical choices belong with qualified clinicians. Robot.help explains what the machine is for so you can ask better questions, not so you can self-prescribe a robot.
Moxi: logistics help for clinical staff
Moxi, from Diligent Robotics, is designed around a different pain: nurses and other staff spending shift time on fetch-and-carry. It navigates hospital corridors, can work with elevators where the site is integrated, and uses a mobile manipulator arm for selected handling tasks such as interacting with doors, bins, or items in a mapped workflow.
That is closer to a hotel delivery robot than to da Vinci, with a crucial difference: the environment is clinical. Integration, infection-control procedures, and workflow design are the project. Moxi is not a bedside nurse, not a transporter for patients, and not a device that decides treatment.
Availability is organisational. Healthcare customers in selected markets, primarily discussed around the United States, deploy it after site assessment and training. A visitor asking “can I buy Moxi for home care?” is asking the wrong channel and the wrong job. Home care logistics are a different product set.
PARO: therapy and engagement, not assistance
PARO is an interactive therapeutic robot in the form of a baby seal. It responds to touch, sound, light, and posture with movement and seal-like sounds. It is used in dementia care, rehabilitation, paediatric settings, and some home care environments where calming interaction is the goal.
PARO does not walk the ward, fetch water, or monitor vital signs. Its value, when it has value, is social and sensory. That is why it can be appropriate in a care plan and still be the wrong answer to “we need help lifting patients”. Cost is typically in the thousands of US dollars through authorised distributors, not toy-aisle money, which is a common shock for families who saw a cute photo first.
If you are considering PARO for a relative, involve the care team. A therapeutic robot is not a substitute for staffing, medication review, or human contact. It is one possible engagement tool. Language, hygiene of the covering, and who will actually present the robot day after day matter more than the unboxing.
How hospitals (and families) should compare them
Never score these three on a single spreadsheet of “autonomy” or “AI”. Score each against its job.
da Vinci questions
Procedure mix, surgeon training, utilisation, service contract, OR integration. Not: can it round on patients.
Moxi questions
Walking time recovered, lift integration, infection control, what happens when it is stuck. Not: can it operate.
PARO questions
Who uses it, infection-control cleaning, cost versus other engagement tools, no over-claim on clinical outcomes.
Staff walking time is a fair measure for Moxi, the same way it is for hotel robots in the service-robot cost framework. It is a nonsense measure for PARO. Patient-outcome claims for any of these machines belong in clinical evidence, not in a marketing adjective.
What this means if you are not a hospital buyer
Patients: ask what system your hospital uses and who controls it. A robot in the room does not mean a robot is making decisions about you.
Families looking at home care: a companion or therapeutic robot might be relevant; a surgical system is not. Read personal robot versus wearable alarm before you spend on presence instead of an emergency path.
Operators of clinics and care homes: pick the job. Logistics, surgery, and therapy are three procurements. Mixing them in one “innovation budget” is how unused machines end up in a storage room.
Clarifying checklist
Name the job before you name the robot
- Is the need surgical capability, staff logistics, or therapeutic engagement?
- Who is accountable when the machine is in use — surgeon, nursing unit, or activity staff?
- Is this a capital programme with training, or a device a family can place on a chair?
- What happens to care if the robot is charging, offline, or awaiting service?
- Have we avoided health claims the manufacturer does not stand behind?
Final Thoughts
Hospital robots are specialised tools. da Vinci, Moxi, and PARO are useful precisely because they are narrow. Compare them on Robot.help in the medical category as three different answers, and be wary of any sentence that starts with “the hospital robot of the future” as if there were only one.
Frequently Asked Questions
Does da Vinci operate by itself?
No. A trained surgeon controls the system. The robot does not choose patients or procedures.
Can Moxi care for patients?
No. Moxi is built for hospital logistics: moving items so people can stay with patients. It is not a caregiver.
Is PARO a medical device I can buy like a tablet?
It is sold through authorised channels and used in care settings. Expect distributor pricing and a conversation with the care team, not a casual add-to-cart for a gadget.
Are these available worldwide?
No. Surgical systems, hospital robots, and therapeutic robots all follow regional regulation and distributor coverage. Confirm locally.
Should I buy a hospital robot for a parent at home?
Not these three as a set. Home needs are usually safety, communication, or companionship — different products, and often a wearable alarm first.
