Quadruped

A four-legged walking robot, often inspired by dog or cat morphology. Quadrupeds balance stability (can maintain static balance) with agility (dynamic gaits like trotting and bounding). The Unitree Go2, Boston Dynamics Spot, ANYmal, and MIT Mini Cheetah are prominent examples. Quadrupeds are used for inspection, surveillance, rough terrain traversal, and as research platforms for locomotion.
