Social Robots in the Real World
Researchers are developing new ways for social robots to interact with users and help accomplish specific tasks. Below are details about two trailblazing robots.
Bandit was designed by Maja Matarić’s research lab at the University of Southern California to encourage and teach social behavior to children with autism, as well as help stroke patients with their physical rehabilitation exercises, and the elderly with physical and cognitive exercises.
Increasing evidence shows that robots can inspire social behavior in children with autism. To the right, Bandit approaches a child, using gestures and a playful outflow of bubbles to encourage the child to interact with it and with the parent.
To regain movement in a limb disabled by a stroke, patients have to be encouraged to repetitively move that limb, with no physical assistance, for many hours at a time, while under supervision. Few physical rehabilitation facilities can offer such time-intensive training, and almost no one can afford it at home.

The robot also monitors patients’ progress and ensures proper compliance with the therapy regimen. (Photo credit: USC)
Video: Human-Robot Interaction with Children with Autism"
A second video demonstrating what this robot can do can be found here.
As director of the Social Intelligent Machines Laboratory at George Institute of Technology, Andrea Thomaz has led the creation and development of Simon, a robot designed to learn from humans the way a person would -- through observation, demonstration and social interaction, then respond through actions ranging from using social cues to doing a new task. Said Thomaz, "Our goal is for the robot to go beyond its machine programming to learn from a human who knows nothing about robotics and can teach it just as if he or she was teaching a person."
Thomaz, however, wants robots like Simon to do more than be able to learn and do. "With collaboration, we want the robot to be able to participate in teamwork activity with another human. Emotional intelligence is also important because emotions communicate a lot of important information needed for collaboration... You need to be able to tell when someone is overworked so you can help them out a little bit more." Thomaz also points out the need for a robot to understand a person's intentions. "A lot of research shows that people are really good at perceiving people’s intentions and goals from their actions."
