# Can a robot feel pain?

**No robot on DEPLOY's record is verified to feel pain the way a human does.** At this time, no robot on DEPLOY's record is verified to feel pain the way a human does. Several labs are building and testing pain-like damage sensing, from artificial nociceptors to injury-detecting electronic skin that triggers a protective reflex. That is damage detection and reflex, attributed to those labs, not sentience or human pain.

## Short answer

There is no verified robot on DEPLOY's record that feels pain the way a person does. What is real, and attributed below to the labs and papers that produced it, is a body of research on pain-sensing hardware. Teams at Osaka University and City University of Hong Kong have built artificial pain nervous systems and injury-detecting electronic skin that flags a harmful force and fires a protective reflex, the way a hand pulls back from a hot stove. Engineers and neuroscientists are careful to call this nociception, damage detection and reflex, not the felt, conscious experience that the word pain means for a person. A neuroscientist who reviewed one demonstration described it as a device for communication, not a robot computing an inner experience, and a philosopher reviewing the field argued that because robots lack nervous systems and living bodies there is little reason to expect they could feel pain. DEPLOY does not settle that question. It scopes the answer to its record and attributes every research claim to its source, so you can read the evidence and judge it yourself.

## What labs build vs what it means

- **Labs building it (Osaka, City University of Hong Kong): Pain-sensing hardware is real.** Research teams have built artificial pain nervous systems and injury-detecting electronic skin that flags a harmful force and fires a protective reflex. This is the labs' own work, attributed to them, and they describe it as damage detection, not felt experience.
- **Neuroscientists and philosophers (Sheffield and others): Nociception is not sentience.** Reviewers of this work argue that a reflex to a harmful stimulus is nociception, not the felt, conscious experience the word pain means for a person. One neuroscientist called a leading demonstration a device for communication, not proof of an inner life.
- **Where it stands: No robot verified to feel pain.** At this time, no robot on DEPLOY's record is verified to feel pain the way a human does. Until that changes, the answer stays a scoped absence, and the attributed research below is what is real right now.

## The state of the evidence

| What the research shows | Kind | Date | Who | Source |
| --- | --- | --- | --- | --- |
| A robot skin that detects injury and pulls the limb away by reflex. A City University of Hong Kong team led by Xinge Yu published a neuromorphic electronic skin in PNAS that encodes touch into nerve-like pulses, flags a force above a set threshold as a pain signal, and fires a fast protective reflex to withdraw the limb. The researchers describe damage detection and reflex, not a subjective experience. | Damage-sensing e-skin | Dec 22, 2025 | Xinge Yu and colleagues, City University of Hong Kong | [PNAS](https://www.pnas.org/doi/10.1073/pnas.2520922122) (2025-12-22), [TechXplore](https://techxplore.com/news/2025-12-robotic-skin-humanoid-robots-pain.html) (2025-12-30) |
| A philosopher argues robots are unlikely to feel pain, because pain is not the same as nociception. Amanda Sharkey argued in AI & Society that pain implies sentience and the capacity to suffer, while a robot's reflex to a harmful stimulus is nociception. Because robots lack nervous systems and living bodies, she concludes there is little reason to expect they could feel pain. This is a philosophical argument, attributed to the author. | Philosophy paper | Nov 3, 2024 | Amanda Sharkey, University of Sheffield | [AI & Society (Springer)](https://link.springer.com/article/10.1007/s00146-024-02110-y) (2024-11-03) |
| An artificial pain nervous system driving a child robot's facial expressions. Minoru Asada's Osaka University team wired damage-and-touch sensors in soft skin to Affetto, a child-like robot head, so a hard press produces distress-like expressions. Neuroscientist Antonio Damasio, quoted in the coverage, called it a device for communication rather than a robot computing an inner experience. | Demonstration | Feb 16, 2020 (as reported) | Minoru Asada team, Osaka University (reported by Science News) | [Science News](https://www.sciencenews.org/article/robots-feel-pain-artificial-intelligence) (2020-02-16) |
| A hypothesis that a pain nervous system could scaffold empathy and a conscious mind in robots. Minoru Asada argued in the journal Philosophies that giving a robot an artificial system to sense damage could be a developmental route toward empathy, morality, and a sense of self. He frames this as a working hypothesis about future artificial minds, not a claim that today's robots feel pain. | Research hypothesis | Jul 13, 2019 | Minoru Asada, Osaka University | [Philosophies (MDPI)](https://www.mdpi.com/2409-9287/4/3/38) (2019-07-13) |

## Common questions

### Do robots feel pain?

No robot is verified to feel pain the way a person does. Some robots have pain-sensing hardware: skin that detects a damaging force and reacts by reflex. Researchers call that nociception, damage detection, and attribute it to their own labs. It is not the felt, conscious experience the word pain means for a human, and no lab claims otherwise.

### Can a robot hurt a human?

Yes, a physical robot can injure a person through a collision or a malfunction, which is a safety question DEPLOY tracks as dated, sourced incident records, separate from this page. That is different from the robot feeling pain itself. A robot causing harm and a robot experiencing harm are two distinct questions, and only the first is documented on the record.

### Can AI feel pleasure?

There is no verified system that feels pleasure. As with pain, some research explores reward signals that shape a machine's behavior, which engineers attribute to their own models as computation, not felt enjoyment. DEPLOY has no record of a robot or an AI that experiences pleasure, and treats any such claim as attributed to whoever makes it rather than as an established fact.

### Can a robot feel happy or sad?

A robot can display expressions that look happy or sad, and some research robots are built to do exactly that, which their makers attribute to themselves as designed behavior. Displaying an emotion is not the same as feeling one. No robot on DEPLOY's record is verified to have an inner emotional experience, so the honest answer is that the expression is real and the feeling is not established.

### Will robots ever feel like humans?

That is an open question no one can answer from the record today. Some researchers, such as Minoru Asada at Osaka University, hypothesize that a pain-sensing system could one day scaffold empathy and a conscious mind, and others, such as Amanda Sharkey, argue that robots lacking living bodies are unlikely to ever feel as humans do. Both are attributed views, not settled findings. DEPLOY will not predict it; it will record verified capability as and when it arrives.
