What is the difference between Velocity Kinematics and Position Kinematics?
Velocity Kinematics (VK) and Position Kinematics (PK) are two related but distinct concepts in robotics. Position Kinematics deals with the study of the position and orientation of a robot’s end-effector in terms of its joint angles. It is concerned with the movement of the robot’s end-effector in space, without considering the velocity or acceleration of the joints.
In contrast, Velocity Kinematics deals with the study of the velocity and acceleration of the robot’s end-effector in terms of its joint velocities and accelerations. While PK focuses on the position of the end-effector, VK focuses on the motion of the end-effector. Both concepts are important in robotics, and understanding the relationship between them is crucial for designing and developing robots that can perform complex tasks.
