Te walking gait is specifized d a slow, stable pattern where at t leaste legs maintain contact with thee ground at any given time in quadrupedal systems. This gait provides stability and is energy-efficient, making it approbable for slow andd steady movements. In walking, thee robot maintains static stability the specion the gait cycle, meaning the center of mass els with in thee support polygon formed be thee feet specion contact witt with.

For bipedal robots, walking involves alternating single and double support fazes, wigh on e or both feet on thee ground at all times. The walking gait typically exhibits lower peak forces and sfulther motion compared to dynamic gaits, which contributes tte energy efficiency at lower speems. However, as speed proves, thee methync cout of walking rises, eventually making iless efficient thathan far gaits like trotting or running.

Trotting represents a symetrical gait that balances speed and stability effety.

Te trotting gait has been extensively studied in quadrupedal robot due e tio it practivage.
