What class of robot axes includes the waist, shoulder, and elbow?

The waist, shoulder, and elbow are components that are integral to the robotic arm's movements and functionality. This class of robot axes is classified as the "Body class" since these joints facilitate the primary motion and positioning of the upper part of the robot, commonly mimicking human-like arm movements.

In robotic systems, the body class encompasses the joints that contribute to the overall reach, dexterity, and manipulation capabilities of the robotic arm. The waist enables rotation and positioning, while the shoulder and elbow joints allow for lifting and bending actions. This classification is essential for understanding how robots are designed and programmed to interact with their environment, particularly in tasks that require human-like movement.

While other classes might pertain to different parts or functions of the robot, the specific focus on the waist, shoulder, and elbow connects directly to the manipulation and arm mechanisms, confirming the relevance to the body class.
