What is meant by bipedal locomotion in robotics?

Bipedal locomotion in robotics refers specifically to the movement of a robot that mimics human walking on two legs. This concept is crucial in the design of humanoid robots, which aim to replicate the way humans move. Bipedal locomotion involves complex dynamics including balancing, navigating obstacles, and maintaining stability, which are essential for effective mobility in environments designed for humans.

In contrast, other forms of locomotion, such as using four limbs, rolling on wheels, or hopping, do not pertain to bipedal movement. Four-limb locomotion refers to a quadrupedal design, often found in certain types of robots mimicking animals. Rolling on wheels describes wheeled locomotion, which is more efficient over flat surfaces but doesn't resemble human movement. Lastly, hopping or jumping indicates a different method of propulsion and mobility that does not involve consistent walking or balancing on two legs. Thus, the focus on mimicking human-like walking distinguishes bipedal locomotion from these alternative forms of movement.
