An industrial robot is a robot used in industry.

Industrial robots are manufactured, among other things by ABB, FANUC, IGM, KUKA, Yaskawa Motoman and Kawasaki Heavy Industries.

4 Advantages of industrial robots

Working

The robot has a certain mobility, for each workpiece it is to work with, the robot is provided with a suitable tool. A robot that is used to move a part to a mobile phone must therefore be partially rebuilt and reprogrammed when it is to move another piece.

Industrial robot tools

Some examples of tools for Industrial Robots;

Parallel grips, grippers with normally 2 fingers moving in parallel. Can grip internally by opening, and can grip something by closing.

Needle grips, a gripper with pins that can be pushed out, to grab something, and that can be retracted again to release. Needle grips are used to move, for example, textiles or foamed plastics.

Suction cups that lift workpieces using a vacuum require smooth surfaces.

Electromagnets for lifting metallic workpieces.

Programming

When programming robot movements, the robot's movement to different points is specified in a three-dimensional coordinate system, but this is entirely dependent on what it is for a robot, for example a robot can have completely different functions than moving in a 3D world. The coordinate axes are usually denoted X, Y and Z and there are six elementary movements in such a coordinate system: translation (rectilinear motion) along X, Y or Z rotation about X, Y or Z

Depending on how the robot manipulator is designed, it can perform some or all of these movements. This number of possible movements is called degrees of freedom. A robot with six degrees of freedom can perform all the movements. A robot that can only perform the three rectilinear movements has three degrees of freedom.

To program an industrial robot, there are two main methods:

Online programming, you run / "jog" the robot to different positions and save them. These are then "played", which is the program.

Offline programming (OLP), where you use an external program in a regular computer that is not connected to the robot to program the coordinates and movement patterns with "written" code. In OLP, there are mainly two program orientations and how to program. The first and oldest variant that requires a great deal of programming knowledge is a "simple" edit where you enter code by hand. The second and more modern uses a 3D environment where you model the entire robot cell. In the virtual environment you can then control / program the robot by "driving" the robot to different positions and storing them and also by writing code. The code you then get can then be downloaded to a physical robot.

The latter option goes hand in hand with robot simulation. under the name CAR, "computer aided robotics".


Tool center point

Tool Center Point (TCP) is the point on an industrial robot that does not move when rotating the tool and which the programmer has as a spatial zero point and reference point during programming. As a rule, TCP is located at a physical point on the tool, for example at the end of a welding nozzle, but may also be located at a certain distance from the tool. A robot typically has several TCP, for example for different tools, but only one TCP can be active at a certain time.

Benefits of industrial robots

The working environment for humans becomes better, since the robot can perform heavy, monotonous and dangerous tasks

The quality of what is produced increases and the rejection decreases, as the robot performs a process in exactly the same way every time

As robots are flexible and reprogrammable, the possibility of changing production increases

More efficient production at lower cost

Increased use of automated robots can reduce the number of employees in the industry.
