They show promise in domains including healthcare, space exploration, disaster response, and other industries due to their ability to change shape to fit various activities and circumstances.Named "mCLARI," the team claims that their prototype can naturally alter its shape, allowing it to maneuver through narrow places in various directions without controlling its movements.

“This robot has four independently actuated leg modules with 2 degrees of freedom, each driven by piezoelectric actuators. The legs are interconnected in a closed kinematic chain via passive body joints, enabling passive body compliance for shape adaptation to external constraints.” explained the release.Furthermore, the robot exhibits a novel ability to move in all directions within confined spaces — known as "omnidirectional laterally confined locomotion.

Jayaram further added: "If you have a slightly more size, you can carry more weight. You can have more sensors. You'll have a longer lifetime and be more stable. But when you need to, you can squish through and go into those specific gaps, such as inspection access ports in a jet engine.”
