Squishy robots: Phase-changing material could allow even low-cost robots to switch between hard and soft states
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.

Two 3D-printed soft, flexible scaffolds: The one on the left is maintained in a rigid, bent position via a cooled, rigid wax coating, while the one on the right is uncoated and remains compliant (here, it collapses under a wrench).
