The robot walking unit is an important part of the robot, its task is to enable the robot to walk, so as to perform various tasks and actions. Robot walking unit usually includes gait planning, motion control, mechanical design and other parts, but also needs to consider the cooperation and integration with other robot parts.

The most common form of robotic walking unit is bipedal walking, which is often seen as the form of robot that most closely resembles human walking. Bipedal robots need to mimic the walking gait and movements of humans, while having stability and good balance to avoid falling down or other abnormal behaviors during walking. This requires a combination of machine vision, gyroscopes, accelerometers and other sensors to achieve.

The gait planning of bipedal walking is one of the core parts of the robot walking unit, its task is to determine the gait and movement of the robot in a given environment to realize the robot walking. Different from other robot components, gait planning needs to solve more complex problems, need to consider a number of factors, such as walking speed, stride length, body balance and complex terrain. Gait planning usually adopts positioning, Estimation, Control (LEC) technology, that is, the environment is estimated through sensors and algorithms, and then the gait and movement of the robot are determined according to the environmental information.

The design of the robot walking unit also needs to consider the mechanical characteristics of the robot during the walking process. Mechanical design is the process of determining the mechanical model of the robot walking and using reverse dynamics (ID) for dynamic simulation. This design needs to analyze many factors such as the robot's center of mass, center of inertia, and the bearing capacity of the rods to determine the mechanical characteristics of the robot in different environments and tasks.

In addition to bipedal walking, the robot walking unit also includes other walking forms, such as foot wheel combination and four-legged walking. These forms of robot walking units need to be designed and manufactured according to their respective mechanisms and functions.

At present, the research and application of robot walking units have developed rapidly, especially in industrial, military and medical fields, and robot walking units have achieved many results and successful cases. In the future, people will continue to study and improve the technology and application of robot walking units to promote the development and application of robots.
