Velocity kinematics

Definition

Velocity kinematics refers to the study of the motion of objects in terms of their velocity, which is the rate of change of position with respect to time. In robotics, understanding velocity kinematics is essential for controlling the movement of wheeled and tracked robots, as it allows for precise navigation and maneuvering. This concept encompasses various factors such as speed, direction, and acceleration, which together influence how robots interact with their environment.
