Autism is a common and often debilitating developmental disorder affecting between one in 80 and one in 240 children in the United States. The use of robotic systems is a promising technological possibility for enhancing the often-intensive therapy these children require. Anecdotal evidence and case studies suggest that not only are robots highly salient to children with autism, but that those children may exhibit social behaviors with robots that they do not otherwise use. A number of research groups (including our own) have used robots with children with autism. Our research focuses on augmenting existing therapies using SAR (Socially Assistive Robotics), extending and enriching care from a human therapist while recognizing the critical importance of maintaining and improving human-directed social behaviors in these children.
