Robotic legged locomotion

Definition

Robotic legged locomotion refers to the ability of robots to move using legs, mimicking the walking, running, or jumping patterns seen in biological organisms. This type of movement is often achieved through complex control mechanisms that replicate the natural motion and coordination of animal limbs. The efficiency and adaptability of robotic legged locomotion are significantly enhanced by the integration of central pattern generators, which provide rhythmic control signals for movement.
