What are the basic components of industrial robots?

Basic components of industrial robots include manipulators, actuators, sensors and control systems. Manipulators are the robotic arms that move objects, actuators are the motors that drive those movements, sensors provide feedback, and control systems coordinate all the components. Manipulators often consist of several joints that allow different degrees of freedom of movement, enabling the robot to perform complex tasks. Actuators, which can be hydraulic, pneumatic or electric, convert energy into mechanical movement. Sensors such as cameras, laser scanners, and force meters provide data that allows the robot to sense its environment and adapt accordingly. The control systems include computer programs that coordinate the operation of all components and ensure that the robot accurately performs the prescribed tasks.

Manipulators are a key component of industrial robots, as they are responsible for the actual movements and movements that the robot performs. These manipulators usually consist of several segments or joints that are interconnected by joints. Joints allow movement in different directions and thus greater flexibility in performing tasks. Each joint is usually connected to an actuator that provides the power for movement.

Actuators are motors or drive mechanisms that convert energy into motion. There are different types of actuators used in industrial robots, including electric, hydraulic and pneumatic actuators. Electric actuators are the most common as they are precise and easy to control. Hydraulic actuators use pressurized fluid to create motion, allowing for greater power, but are more complex and require maintenance. Pneumatic actuators, on the other hand, use compressed air for movement, which is easy and affordable, but less precise.

How are industrial robots programmed?

Programming industrial robots involves writing code and using specialized software tools that determine how the robot moves and performs tasks. Programs can determine the movement of robots in three-dimensional space, their speed, the force with which they grip objects, and the time intervals for individual operations. One programming method is learning by imitation, where the robot moves through desired actions with the help of a human operator, and then repeats those actions independently. Another method is programming using codes, where programmers use special languages ​​such as RAPID or KRL to write precise instructions for the robot.

In imitation learning, the operator physically guides the robot through desired actions. This means that the operator moves the robot arm, e.g. picks up an object and moves it to a specific location. The robot saves these movements and then repeats them independently. This method is useful for tasks that require complex and precise movements, as it allows the operator to adjust the movement of the robot according to the specific requirements of the task.

Programming using codes is more technically demanding and requires knowledge of programming languages ​​and algorithms. Programmers write precise instructions for the robot, specifying how it should move, with what speed and power. These programs also include logic conditions that allow the robot to respond to changes in the environment. For example, if a sensor detects an obstacle, the program can redirect the robot’s movement to avoid a collision.
