In robotics, what does "kinematics" refer to?

Kinematics refers specifically to the branch of mechanics that deals with the motion of objects, in this case, robots, without considering the forces that cause that motion. It focuses on understanding how various parts of a robot move and how their movements are interrelated, particularly in the context of robotic joints and linkages. This involves analyzing trajectories, velocities, and acceleration profiles, which are fundamental for programming and controlling robotic movements accurately.

In contrast, the study of robot designs pertains to other aspects of robotics engineering, such as selecting materials or structural configurations, while the analysis of robot sensors focuses on understanding how robots perceive their environment. Maintenance procedures would concern the upkeep and repair of robotic systems, which is a separate consideration from the kinematic analysis of movements. Thus, the definition that encapsulates kinematics most accurately is the one relating to the study of the motion and joint movement relationships within robots.
