Robot locomotion covers walking, running, rolling, flying, swimming and other forms of movement. The robot must coordinate actuators while using sensor feedback to maintain stability, follow a path and respond to changing surfaces or obstacles.
Locomotion performance depends on mechanical design, control frequency, power, balance and motion planning. Speed is only one measure: efficiency, recoverability, terrain handling and safe interaction are also important when judging whether a system is useful outside a demonstration.

Robot locomotion covers the ways a robot moves through its environment, such as walking, running, rolling, flying, or swimming. The robot coordinates its motors with sensor feedback so it can stay stable, follow a route, and respond to obstacles.
For example, a legged robot crossing uneven ground must adjust each step while preserving balance and direction. Useful locomotion is judged by safety, efficiency, recovery, and terrain handling as well as maximum speed.
How does a walking robot stay upright?
It combines sensor measurements with fast control updates that adjust joint forces and foot placement to keep its center of mass within a recoverable region.
Why is robot locomotion difficult?
Real surfaces, impacts, delayed sensor data, actuator limits and unexpected disturbances require movement plans to be corrected continuously and safely.
