Industrial Robot Market
The industrial robot market is an growing market and is currently worth about $ 35 billion and this value is expected to grow rapidly. The number of robots working in this market is 2.6 million as of 2019. So how do industrial robots, the product of such a large market, work and what do they consist of? Industrial robots consist of 3 main components;
Mechanical
Electronic
Computer science
The mechanics of a robot is the part of the body that you can see when you look at the robot. Our mechanical engineers work gracefully for the speed, precision and load of the robot. The robot’s electronics enable the command system to start all engines and receive environmental information from sensors. Computer science, on the other hand, is the component that makes the robot “smart” in the shortest term with the robot environment and user cooperation.
Cartesian Robot :
A Cartesian robot moves linearly along 3 Axes (X,Y,Z). Cartesian robot solutions are one of the easiest and cheapest in in using of Industrial robot. For example, it gives good results when used for 3D printing, however, it has a limited use because routing management is limited.
Multiple Degrees of Freedom Robots: These are robots with freedom of movement in many directions. They are often used in the direction of 3 axes and 3 effectors with 6 axes. The robot can direct it in any direction to any point. This solution is better for multitasking and complex operations, although the price is higher. The use cases for polar robots are unlimited.
Robot Ladder: A SCARA Robot is a mixture of the above two robot categories. It can move along 3 axes (X, Y, Z), but can only guide the end effector in one direction. This type of robot is more specific and performs well for “take and place” tasks.
What Is Robot Control System?
The task of a robot control system is to maintain the planned operating system even when unforeseen errors occur. It realizes precise control of position, speed, force and torque in both cartesian and articular areas.
Robot Control Techniques
Open Loop Control (Nonservo Control) : This technique has no feedback. It is suitable for systems with simple loads. It doesn’t need strict speed control. It is used in stop or ‘pick-place’ systems.
Feedback Control Loop: A technique that determines rotor position and speed through one or more sensors. The position of the robot arm is monitored by a position sensor, the power to the actuator, the movement of the arm is changed to suit the desired path in terms of direction and speed. In this way, errors in positioning can also be corrected.
Feed-Forward Control: A technique used to predict how much a robot model will process and the amount of energy to be used.It is used to predict actuator settings for processes where feedback signals are delayed and processes where the dynamic effects of interference need to be reduced.
Adaptive Control: This control uses feedback to update the model of the process based on the results of previous actions. Measurements of the results of previous actions are used to adapt the process model to correct errors in and in the process model.
