The manipulator can be considered as open chain of a sequence of links interconnected by powered joints to control the position between links. It means that the motion of the manipulator is generated by a set of drives or actuators, which may be electrical, pneumatic, hydraulic or mixed.
Robot:
Is a programmable multifunctional manipulator designed to move material, parts, and tools through variable programmed motion along several directions for the performance of variety tasks.

Kinematics:
Is the analytical study of the geometry of motion of robot arm with respect to a fixed reference coordinate system (base frame) without regard to the forces or moments that cause the motion.
