Robots changing their shape

The more research of Artificial Intelligence the more we get of Robots.Human automation is being more advanced with time but the problem remain same i,e rigidity.Robots are made of metals and other hard materials,although the skeletal structure are same as humans but remains stiff and inflexible.

However this scenario might change in the near future since some researchers from MIT and other universities of USA have developed a material that will allow the robots to be soft.Using a 3D printed phase changing material composed of polyurethane foam and wax researchers can use heat variances to manipulate the softness and hardness of the structure.

The prototype model was a snake robot.Their objective was to allow it to enter into a 1 cm opening and reach the other side.The use of foam and wax makes the whole process more affordable and simple.Other application of the same technology would even allow the robots to self heal but that is still in infancy stage.
