SCARA robots

SCARA robots have a maximum of four degrees of freedom but can also be equipped with just three for very simple tasks. These robots are used for assembly tasks of aU types, for simple loading and unloading tasks, and for fitting of electronic components to printed circuit boards. 

Industrial robots are built in different setups. The most common are the SCARA (selective compliance assembly robot arm) robot and the six-DOF robot. The SCARA robot usually has four DOF, three translational and one rotational, whereas the z-stroke represents the actual working direction. The other axes are used for positioning. SCARA robots are often used for assembling small parts automatically with very short cycle times. Six-DOF robots are used for more complex tasks because they are more flexible in their movements so they can grip parts in any orientation. 

The SCARA robot class is actually a subclass of the cylindrical coordinate robots. It is still considered to be a separate class because of its unique properties. It was introduced as a robot particularly suited for assembly tasks, and it is for assembly and similar light operations it is widely... 

Automated production requires a workpiece carrier that can be used all the way along the production line. Consequently, the design is such that the carrier can be conveyed by the printed-circuit board conveyor to all the machines in the process chain. The appropriate number of workpiece carriers is required if production is to be continuous. An interface for energy supply and communication between the automatic machines and the workpiece carrier is necessary, particularly for the dispensing unit and the automatic placement machines. The electronics built into the workpiece carrier render it unsuitable for reflow soldering, so a handling step has to be included so that the MID can be lifted on to a separate, passive workpiece carrier for this process. This transfer can be manual or by means of an industrial robot such as the Scara robot. 

A Selective Compliant Assembly Robot Arm robot manipulator is used at Allegany Ballistics Laboratory . The robotic arm is an IBM 7540 Model A02 Robotic System Cl3. The IBM 7540 System is a continuous path robot and consists of a manipulator, controller, control panel, and a computer system.

The first robot with all joints electromechani-caUy driven was the Famulus introduced by the German company Kuka in 1973. Then in 1974, the Cincinnati MUacron robot T3 was the first robot to have a minicomputer-based control system that offered full CNC type of linear path control. In decade 1970-1980, a number of manufacturers entered the scene, and the various types of industrial robots we see today were introduced. The last one in this line was the SCARA (Selective Compliance Robot Arm) developed by Hiroshi Makino in 1978 (IFR 2012).

The test environment that has been set up consists of a Bosch Scara arm, where the camera and light source are placed at the end effector. The Bosch controller is connected to a SUN workstation, on which the robot program is generated. This SUN workstation is also used by the HLI, and the calibration software. The sensor processing hard- and soft-ware is located in a VME crate, allowing easy exchange of components without rebooting the entire system.
