According a Wired article, humanoid robots are being used in British schools to teach social skills to autistic children. It's a perfect match because robots don't grow impatient with the children and autistic children frequently don't react well to human teachers. The humanoid robots offer much easier to understand interactions to the child, providing a stepping stone to dealing with the more complex interaction needed with other humans. The teacherbots are known as KASPAR robots (Kinesics and Synchronisation in Personal Assistant Robotics) and cost about $4.3 million each. They consist of a silicon-rubber mask over an aluminum frame with 8 DOF in the head and neck, 6 DOF in the arms and hands. It also has 2 DOF eyes with integrated video cameras.
