Future “Squishy” Robots by MIT Researchers.

Researchers at Massachusetts Institute of Technology have developed an intriguing material that can change between soft and hard states on command.

A new phase-changing material built from wax and foam developed by researchers at MIT is capable of switching between hard and soft states.
Robots built from this material would be able to operate more like biological systems with applications ranging from difficult search and rescue operations, squeezing through rubble looking for survivors, to deformable surgical robots that could move through the body to reach a particular point without damaging any of the organs or vessels along the way.

In the movie “Terminator 2,” the shape-shifting T-1000 robot morphs into a liquid state to squeeze through tight spaces or to repair itself when harmed.

Now a phase-changing material built from wax and foam, and capable of switching between hard and soft states, could allow even low-cost robots to perform the same feat.

The material — developed by Anette Hosoi, a professor of mechanical engineering and applied mathematics at MIT, and her former graduate student Nadia Cheng, alongside researchers at the Max Planck Institute for Dynamics and Self-Organization and Stony Brook University — could be used to build deformable surgical robots. The robots could move through the body to reach a particular point without damaging any of the organs or vessels along the way.

Robots built from the material, which is described in a new paper in the journal Macromolecular Materials and Engineering, could also be used in search-and-rescue operations to squeeze through rubble looking for survivors, Hosoi says.
