# Legged Robots Extend Into New Physical Environments

Bio-inspired legged and mobile robots increasingly move beyond flat ground into novel physical media and tasks — water surfaces, rescue, unstructured terrain — using model-predictive control and cheap actuation; expect recurring demonstrations expanding the operating envelope of embodied platforms.

- [confirms] Researchers Build a Four-Legged Robot That Walks on Water to Pull Drowning Victims Out (2026-07-26): Researchers in Shenzhen and New Jersey built the QuadBoat, a fishing-spider-inspired four-legged robot that uses model-predictive control to stand, move, and retrieve drowning victims on the water's surface. A demonstration of legged locomotion in a new physical medium (water) for rescue.
