In a few words what do you think about This soft robotic arm that is straight out of Big Hero 6 (it’s even from Disney).

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 effect of protecting the servos from humans and vice versa, while also allowing natural tactile interactions.

“Distributing individual modules over the various links of a robot provides contact force sensing over a large area of the robot and allows for the implementation of spatially aware, engaging physical human-robot interactions,” they write. “The independent sensing areas also allow a human to communicate with the robot or guide its motions through touch.”

Explanation / Answer

The robotic arm initially has various applications in indutries, but they are rigid and often heavy. But the robotic arm baymax is very differant(I have watched the movie) the arm that is displayed in the link is displayed as of the oute air filled cushion is made of plastic like thing. But I think the outer pillow like thing must be made of soft rubber which will give a real smooth and cusion feel. But with the covering of the things and all there must be a regulating system such that when arm is folded the pressure is mainly concentrated at the elbow itself. The variation in thickness of sheath overe the robotic arm can really decrease the complexity of pressure variation as increasein thickness will take care of it. The regular maintenance could be a bigger problem as the removal of outer covering is must after the work is complete the filling of the sheath should be done. In dynamic environment the sheath may be subjected to wear and tear, where some sharp materials could pierce a hole through the sheath. After taking certain necessary precautions this could be a good invention and could be helpful in many ways. The soft layered robot will find huge application in

1. nusing, taking care of old and young people as the softness will bring comfort to them.

2. In kinder garten and pre-primary schools, as the children will even play with the robot. moreover it creates more enthusiasm to the children.( they will no more cry while coming to school)
