Robotic dogs are revolutionizing elder and dementia care by providing therapeutic companionship and reducing reliance on medications.
Magnetic slime robots are emerging as a game-changer in minimally invasive medicine, enabling targeted drug delivery and object retrieval inside the human body.
Together, these innovations mark a shift toward empathetic robotics, machines designed to heal, support, and connect with humans at emotional and biological levels.
They may resemble toys or look like sci-fi monsters, but some of the most unlikely robotic dogs of our time are also some of the most useful. These robots perform a wide range of activities, from soothing frail patients to administering medication within the human body.
Robotic dogs and magnetic slime robots are emerging from laboratories and novelty stores into hospitals, homes, and health centers. Their increased visibility is more than metaphorical; it’s remaking what we mean by care, healing, and the place of machines in our world.
Gone are the days when therapy robots were clunky or overtly mechanical. Today’s robotic dogs are soft, interactive, and surprisingly lifelike. They respond to touch and voice, simulate breathing and heartbeats, and even express subtle ‘emotions’ through eye contact, tail wagging, or gentle whimpers.
In elderly care, particularly with dementia or Alzheimer’s patients, these robots lower agitation, calm anxiety, and instill moments of happiness and clarity. The Townsville University Hospital in Australia has implemented robotic puppies as part of dementia therapy.
Some patients even required fewer medications, highlighting how these devices aren’t just comforting, but potentially therapeutic.
The price range of Magnetic slime and robotic dogs varies greatly depending on their functionalities. Basic variants, such as the Joy for All Companion Pets, which are hugely popular in US and UK eldercare homes, are priced between $150 and $250. These have lifelike barking, touch-sensing, and basic animations.
Semi-luxury models, such as Tombot’s Jennie, which are developed in association with patients and clinicians, are much more sophisticated and priced at approximately $3,000. They have more than 1,200 sensors, extremely sensitive facial recognition systems, and deep-learning algorithms that learn to emulate human-like behavior.

There’s natural apprehension about relying on machines to offer emotional support. But in numerous instances, robotic dogs have filled the bill where human help or medication has failed.
For people with end-stage dementia, verbal interaction may be gone. Still, the reassuring presence of a robotic dog can elicit physical reactions, such as a smile, a hug, or a flicker of recognition.
But experts also warn against excess. Honesty is important. Caregivers should not pretend that these pets are actual animals. Instead, they should present them as companions intended to console and amuse, a therapy tool, not an illusion.
Robotic dogs may speak to the heart, while magnetic slime robots are a wonder of soft robotics that will function inside the human body in ways that are impossible. These jelly-like materials are infused with magnetic particles that can be manipulated and molded remotely by magnetic fields outside the body.
They can extend, contract, divide, and merge simultaneously, behaving like liquids and solids. This unique ability allows them to access small, hard-to-reach areas within the body that standard surgical tools cannot safely enter.
What’s the most thrilling use of magnetic slime robots? Well, non-invasive medical treatment now has every reason to celebrate.
Preliminary research on magnetic slime robots has demonstrated potential in:
Removing swallowed objects, such as button batteries or small magnets, is a common occurrence in infants and young children.
Targeted delivery of medication to organs, tumors, or sites of infection, limiting side effects from systemic exposure to drugs
Carrying out minimally invasive surgeries, by passing through thin tubes or vessels
In-body diagnostics, utilizing embedded sensors that track pH, temperature, or biochemical markers
A team of researchers at the Chinese University of Hong Kong, led by Prof. Li Zhang, showed that these robots can be manipulated. The process is performed through simulated stomachs and airways using external magnets, which pick up foreign bodies and navigate into narrow corners.
Magnetic slime robots have a promising future, but are not ready for hospital use. The biggest concern is biocompatibility. The magnetic material within them, such as neodymium, is toxic if it leaks or breaks down within the body.
Researchers are also developing coats for these machines from silicon dioxide shells or other protective coverings that render them internally usable.
Precision of control, long-term robustness, and retrieval (or degradation) methods are also being actively researched. Perfected, they could limit surgery, save money, and make procedures safer and more accessible, particularly in remote or under-equipped medical facilities.
Whether it's a robotic dog providing comfort to an elderly woman with dementia or a magnetic slime robot aiding a child by removing a battery from their esophagus, these machines symbolize a significant shift in our use of technology. They go beyond simple automation to emphasize empathy, healing, and assistance.
This hints at a future where machines not only perform tasks but also care for us.

Robotic dogs are already enhancing mental well-being, emotional control, and quality of life in dementia and elder care.
Magnetic slime robots, still in their infancy, promise a revolution in internal medicine with their soft, innovative design.
Both technologies share the same theme: robots that meet human needs in intensely personal, detailed, and significant ways.
As costs come down and technology develops, don’t be surprised if your next nurse or surgical aide resembles more of a toy or a blob of goo than a classical machine.
1. What are robotic dogs used for in healthcare?
Robotic dogs provide emotional support in eldercare and dementia therapy. They reduce loneliness, agitation, and may even decrease reliance on medications.
2. How much does a robotic dog cost in USD?
Simple robotic pet models, like Joy for All, cost around $130–140; advanced companionship robots, such as Tombot Jennie, may retail for nearly $1,500.
3. What is a magnetic slime robot?
A magnetic slime robot is a soft, biodegradable, and shape-shifting device guided by magnetic fields for drug delivery or retrieving objects within the body.
4. Are magnetic slime robots safe for humans currently?
Not yet. Researchers are working on biocompatible coatings (like silicon dioxide) to prevent toxicity. Human trials are still pending safety validation.
5. Can robotic pets replace live therapy animals?
Robotic pets complement, but don't entirely replace, live animals in therapy. They offer low-maintenance, safe emotional support where live pets aren’t feasible.
