Manipulator systems are used when pieces have to be moved in different axes and lifted to different places. Robotic manipulators are designed for specific task, i.e. welding or they are universal and can be reprogrammed for different tasks.
Pick-and place robot manipulators are common handling devices in industry. The important component of handling device is a gripper which makes contact and manipulates with the target object. Common types of grippers are mechanical and vacuum grippers.
Mechanical grippers. These normally have two or three gripper jaws which “grip” the workpiece like a hand. Since the jaws are not very flexible they must be adapted to the workpiece. Mechanical grippers can be operated by either fluid power (hydraulics or pneumatics) or electricity.
