➀ Caltech researchers developed X1, a multi-robot system combining a humanoid robot (Unitree R1) and a deployable M4 robot capable of rolling and flying, enabling navigation in complex terrains;

➁ The system demonstrated seamless transitions between walking, driving, and flying modes to overcome obstacles like ponds and stairs in a campus simulation;

➂ Physics-based control algorithms allow autonomous adaptability, aiming to advance cooperative robotics for search, rescue, and dynamic real-world applications.

➀ Engineers developed a soft robotic system using liquid crystal elastomer e-skin with heating elements and pressure sensors for navigation in confined spaces;

➀ The robot employs tip extension and heat/pressure controls to maneuver through human blood vessels and jet engines without friction or damage;

➀ Potential applications include precision medical interventions and industrial inspections in inaccessible environments.
