Currently, robotic manipulators are used in a wide variety of industries. Robotization of many processes is due to the quality indicators of automatic manipulators. They are able to do more work compared to a person, carry out it more effective, while spending less resources and time.
Such a mechanism is an autonomous type device, which consists of two technological parts: a mechanical and a software unit that serves to control the manipulator. The main task of these devices is to move objects in space in order to perform certain production tasks. Robotic arms used in production are an integral part of automated production systems of a flexible type.
The mechanical part is divided into two parts. One of them is directly a system that performs mechanical actions, and the other is responsible for moving the manipulator in space.
The moving part of the manipulator differs depending on the types of links used in the robot. They can be combined and located with each other in different ways, which affects the type of movement of the robot. It can move in space due to progressive movements and corner. In order to make the links work and move the manipulator, a variety of drive systems are used: hydraulic, pneumatic or electric.
In large industries where robots are used in workshops to move objects, rails are used along which the manipulator moves from one end to the other. In places where it is necessary to move the robot in vertical or inclined planes, the robots are equipped with pneumatic suction cups operating on the “walking” principle.
Most of these mechanisms are equipped with special devices that ensure the capture of objects. The robot arm manipulator is currently the most modern and versatile tool for manipulating objects. The capture method is similar to the human hand and is carried out by mechanical “fingers”. However, such a device is not suitable for moving objects having a flat surface.
For such items, special mechanical suction cups equipped with a pneumatic drive are used. Often in industry there is a need to transfer many items of the same type of structure. Then, instead of a hand or a sucker, special designs are used, made to manipulate specific objects. It is not necessary to equip them with mechanical gripping devices. There are many manipulators that are designed for completely different needs, for example, welding, installation of structures that require fixing some elements, processing various surfaces, etc. d.
Any robotic arm cannot perform mechanical actions without an effective control system. There are four types of control: software, adaptive, intelligent and human-assisted control.
Software control refers to the presence in the mechanism of its own hardware, which is represented by mobile computers and logic controllers. According to a pre-programmed algorithm, it performs clearly fixed actions that are repeated in a certain period of time.
The basis of the adaptive part is made up of sensors that act as sensors. They transmit a certain signal based on their position, as a result of which the main control unit makes decisions about the further actions of the robot.
Artificial intelligence is used quite rarely, since this technology is in the process of its development and formation. The idea behind this approach is for the robot to make decisions on its own to achieve the best results based on its intelligence.
The last way is the easiest. Its essence is to control all movements of the manipulator by a person using a remote control, a control panel or any other device to control communication with the manipulator.
Today it is not difficult to buy a robotic arm. Many global companies successfully use them in their production processes. Any organization, in order to maintain its competitiveness, needs to re-equip its production facilities, introduce modern innovative ideas and methods. Without the use of robotics, it is not possible to achieve such results.
An industrial robotic arm can operate around the clock without losing the quality of the work performed, which is not inherent in humans. There is also an optimal use of production space, which reduces the cost of renting additional buildings. The accuracy of work without the influence of the human factor allows you to reduce the percentage of product defects. All these conditions contribute to the payback of the purchased robotics in a short period of time, and, as a result, the subsequent increase in the company’s profit.
