The charming robot at the heart of Disney’s Big Hero 6, Baymax, isn’t exactly realistic, but its puffy bod is an (admittedly aspirational) example of the growing field of soft robotics. And now Disney itself has produced a soft robot arm that seems like it could be a prototype from the movie.
Created by Disney Research roboticists, the arm seems clearly inspired by Baymax, from the overstuffed style and delicate sausage fingers to the internal projector that can show status or information to nearby people.
“Where physical human-robot interaction is expected, robots should be compliant and reactive to avoid human injury and hardware damage,” the researchers write in the paper describing the system. “Our goal is the realization of a robot arm and hand system which can physically interact with humans and gently manipulate objects.”
The mechanical parts of the arm are ordinary enough — it has an elbow and wrist and can move around the way many other robot arms do, using the same servos and such.
But around the joints are what look like big pillows, which the researchers call “force sensing modules.” They’re filled with air and can detect pressure on them. This has the dual …read more
