Robôs sociais em escolas e hospitais
Can Social Robots Help Students and Patients?
Robôs capazes de falar, gesticular e responder a pessoas já vêm sendo testados em escolas e ambientes de saúde. Pesquisas recentes sugerem aplicações promissoras, mas também mostram que seu papel precisa ser cuidadosamente definido.
Contexto
Um social robot não é simplesmente uma máquina industrial que executa tarefas físicas. Ele é projetado para interagir socialmente com pessoas por meio de voz, movimento, gestos ou outras formas de comunicação.
Em 2026, revisões científicas mostraram que esses robôs vêm sendo estudados em educação para atividades como aprendizagem de idiomas e matemática. Uma meta-análise envolvendo 146 estudos encontrou benefícios de aprendizagem em várias situações, mas apresentou um resultado especialmente importante: robôs utilizados como apoio ou coensino mostraram resultados mais positivos do que robôs utilizados para substituir professores. Na saúde, pesquisas também investigam seu uso no apoio a crianças hospitalizadas e em outras formas de cuidado.
READING TEXT IN ENGLISH
Can Social Robots Help Students and Patients?
Imagine entering a classroom and seeing a small robot talking to students.
The robot asks questions, makes gestures and helps children practise a new language.
Now imagine another robot in a hospital.
It tells stories, plays games and interacts with a child who is preparing for a medical procedure.
These situations are no longer only science fiction.
Researchers are studying social robots in education and healthcare.
Social robots are machines designed to interact with people through communication and social behaviour.
In education, robots have been tested in areas such as language learning, mathematics and other cognitive skills.
A large meta-analysis published in 2026 examined 146 studies involving physical social robots and learning. Overall, the researchers found positive learning effects in several situations. However, an especially interesting result appeared when researchers considered the robot's role.
Robots used in a co-teaching role showed stronger results.
When robots were used to replace the human teacher, the analysis found no learning advantage.
This distinction is important.
A robot might provide additional practice, repeat an activity many times or create an interactive learning experience.
But teachers do much more.
They understand classroom relationships, respond to unexpected situations and make complex educational judgments.
Social robots are also being studied in healthcare.
A 2025 systematic review and meta-analysis examined their use with hospitalized children experiencing pain, stress or anxiety. The robots could interact through activities such as stories, songs and playful communication.
A 2026 observational study also examined the experience of hospitalized children, caregivers and healthcare workers interacting with a social robot, reflecting continued research into how this technology might fit into real clinical environments.
These robots may therefore become useful tools.
But an important question remains:
Should a social robot replace human interaction — or support it?
Current research suggests that this distinction matters.
Key Idea
A ideia central não é perguntar simplesmente se robôs são “bons” ou “ruins”.
É perguntar:
What role should the robot have?
Na educação, evidências recentes sugerem diferenças importantes entre um robô utilizado junto ao professor e um robô utilizado no lugar do professor. Uma meta-análise de 2026 encontrou resultados positivos especialmente quando o robô atuava em coensino, enquanto a substituição do professor não apresentou benefício global.
Na saúde, os resultados também precisam ser interpretados com cautela: há potencial para apoio, interação e redução de sofrimento em determinados contextos, mas pesquisadores continuam estudando eficácia, implementação, aceitação e limitações.
A tecnologia pode ser mais interessante quando amplia capacidades humanas, e não quando simplesmente tenta eliminar pessoas do processo.

Language Focus
Support vs. Replace
Estas duas palavras representam uma distinção importante neste tema.
SUPPORT
The robot supports the teacher.
O professor continua responsável pelo processo.
REPLACE
The robot replaces the teacher.
O robô passa a desempenhar a função no lugar da pessoa.
Compare:
AI can support medical professionals.
com:
AI can replace medical professionals.
As frases possuem implicações muito diferentes.
Em textos acadêmicos, escolher o verbo correto é essencial para não exagerar resultados de pesquisa.
