A Systematic Review of Research on Robot-Assisted Therapy for Children with Autism.

This review looked at 38 research studies about using robots to help children with autism learn social skills. The studies showed that autistic children are interested in playing with interactive robots. These robots can help children practice social interactions in a therapeutic setting. Research in this area has grown significantly since 2009, likely due to improvements in artificial intelligence technology.

This systematic review analyzed 38 peer-reviewed articles on robot-assisted autism therapy (RAAT) published from 2009 onward. The review examined research trends and characteristics including publication patterns, robot types, participant demographics, and targeted behaviors. Results demonstrated substantial growth in RAAT research publications over time, indicating increasing interest in robotic technology for autism intervention. The authors suggest this growth is driven by advances in artificial intelligence and machine learning technologies.

The review found that children with autism show interest in interactive robots, which can engage them in therapeutic sessions to practice complex social interactions that mirror human-to-human communication.

Robot-assisted therapy represents an emerging intervention approach that may engage autistic children in social skills practice. The growing research base suggests increasing clinical interest, though specific therapeutic protocols and effectiveness require further investigation. Practitioners should await more robust outcome data before implementation.

This is a descriptive review analyzing research trends rather than therapeutic outcomes. No specific sample sizes, intervention details, or effectiveness data are provided. The review focuses on publication characteristics rather than clinical efficacy or comparative effectiveness of robot-assisted interventions.

Recent studies have shown that children with autism may be interested in playing with an interactive robot. Moreover, the robot can engage these children in ways that demonstrate essential aspects of human interaction, guiding them in therapeutic sessions to practice more complex forms of interaction found in social human-to-human interactions. We review published articles on robot-assisted autism therapy (RAAT) to understand the trends in research on this type of therapy for children with autism and to provide practitioners and researchers with insights and possible future directions in the field. Specifically, we analyze 38 articles, all of which are refereed journal articles, that were indexed on Web of Science from 2009 onward, and discuss the distribution of the articles by publication year, article type, database and journal, research field, robot type, participant age range, and target behaviors.

Overall, the results show considerable growth in the number of journal publications on RAAT, reflecting increased interest in the use of robot technology in autism therapy as a salient and legitimate research area. Factors, such as new advances in artificial intelligence techniques and machine learning, have spurred this growth.
