More than 2.7 million robots are currently working in factories around the world ' more than ever before, according to the International Federation of Robotics (IFR). Articulated-arm robots have the largest share among traditional industrial robots: Their movable robotic arms are reminiscent of the human arm; They can do a wide variety of jobs in a similarly versatile manner. Robotic arms effortlessly lift heavy components, help with production and assembly, or pack and palletize goods. The demand for the use of robotic arms is also increasing in the pharmaceutical and cosmetic industries: Here they are not only used in production, but also in the laboratory. Because they offer the advantage that systems can be quickly adapted to changing requirements. This enables companies to react flexibly to changes in demand and ever smaller batch sizes.
This guide offers an overview of what is possible and useful with robots today, which criteria are decisive when buying and presents some bestsellers.
Thanks to constant technological development, the prices for robotic arms have fallen significantly in recent years. Multifunction robots are available for less than 1,000 euros. Small and medium-sized companies in particular benefit from this trend, because modern robotics now also allow them to automate even high-precision manufacturing tasks in a cost-efficient manner. At the same time, it is becoming ever easier to implement professional robotics and program robotic arms ' today you don't have to be a software expert to train a robot to do its job.
Robots are conquering more and more fields of application ' from healthcare to agriculture. Robots even make a contribution to climate protection: In order to achieve the ambitious climate targets, renewable energies and environmental technologies are being produced on an unprecedented scale. According to the IFR, the components required for this can be produced efficiently even by small and medium-sized companies thanks to robotics and automation. These include fuel cells for hydrogen-powered cars, batteries for the transport sector and solar cells in the energy segment. In addition, modern robots work energy-efficiently and use them to directly reduce energy consumption in production. Thanks to their precision work, fewer rejects and defective goods are produced, which has a positive effect on the use of resources and output.
While the first robots were permanently installed and secured behind fences, they stubbornly performed their work, today they can also move freely as mobile robots. For this purpose, industrial robots are equipped with artificial intelligence, vision kits and other sensor systems. In the near future, they will act as mobile helpers to inform customers when shopping, deliver room service orders in hotels or support police tasks, for example by patrolling urban parks. Corresponding pilot projects can already be found around the world. There is also great demand for disinfection robots, logistics robots in factories and warehouses or robots for delivering goods to the front door.
At the same time, the integration of workplaces with human-robot collaboration is picking up speed. So-called cobots are increasingly working hand-in-hand with people, without any protective fences.
Service robots for personal and domestic use are produced for a mass market ' the largest sales figures are domestic robots. These include vacuum cleaner and floor cleaning robots, lawn mowers and entertainment robots. In alone, more than 23 million service robots were sold worldwide for personal and domestic use, according to the IFR.
In the meantime, there are even inexpensive robot kits with which schoolchildren, students or trainees can gain their first experience with robotics. This means that the IT and STEM lessons leave the dry theory behind. Early childhood education can begin here with the help of screenless learning concepts from an entry age of four years. The degree of complexity can be increased fluently ' up to highly complex robot systems that navigate and act autonomously in space using artificial intelligence and modern visual sensors.
The structure of the robot arms is based on the human arm. They have a high degree of mobility and flexibility ' so they can be used in many applications, for example as palletizing, gripping, testing or welding robots in industry. They are available in different designs: The most important feature is the number of degrees of freedom, i.e. the axes of movement. Four to six axes are common. In order to achieve a greater range, robot arms can also be mounted on a linear axis. Seven-axis robots are most similar to the human arm: They are so agile that they can practically reach around corners.
Which robotic arm is the right one for the respective application depends on various factors. The first important criterion is the task that he is supposed to take on: is it about handling components, or should he pack products or paint components? Based on this basic function, the main functions of range, load and cycle time or speed as well as the degrees of freedom required to carry out the work can be defined.
To determine the required arm length of the robot arm, it is necessary to analyze the application on site and to take various criteria into account. These include questions such as:
The required movements that the robot arm must make with the component are then determined. For example, should it be tilted or rotated 180 degrees? It is also important whether the arm can move directly to the respective position or whether it has to reach around a component. The result of these considerations leads to the required number of axes.
When considering the load, it should be ensured that not only the weight of the component to be handled is taken into account, but also the weight of the required gripper. It is also important to analyze the position of the center of mass in relation to the attachment to the robot arm. If the center of gravity is relatively far away, it makes sense to choose a robot with a higher payload in order to enable a trouble-free and dynamic process.
Another step is to determine the required or desired cycle time. How fast should the robot be in completing its task? This is particularly relevant if the robot arm is to perform handling or processing steps in conjunction with a machine. Because then the processing time of the machine sets the framework within which the robot has to do its work.
Another important determinant is the positioning accuracy that the robot arm achieves. While it is not crucial for packaging tasks, for example, it has to be very high when the robot places components in machine tools.
When deciding to buy a robotic arm, attention should also be paid to setting up the system. Is there someone in your own company who has an affinity for programming machines? If not, a robot system should be selected that is taught the motion sequences 'manually': The robot arm is guided to the respective position by hand. The market also offers robots with intuitive software for applications that often involve changing tasks and small quantities. As a rule, you do not need specialists to put them into operation.
In addition, it must be considered which accessories are required or available. These include, among other things, grippers or camera systems. The safety equipment is also an important determinant ' it depends on where the robotic arm is placed and how high the risk for people and machines is. The periphery within which a robot works and which together with it form the overall application is also important. The periphery specifies which communication interfaces the robot must have in order to exchange information with the other components and to what extent it can be integrated into a higher-level control system. The ROS framework (Robot Operating System) has established itself as an essential standard for overcoming different hardware interfaces. Most of the robots sold by reichelt that can be used in R&D or industrial automation are compatible with this and are therefore particularly easy and flexible to implement.
Depending on the application criteria, robot arms are available for a wide variety of applications:
As broad as the possible applications for robots are, the designs and types are just as varied. It does require some basic considerations in advance, but then a wide variety of tasks can be flexibly automated with robots ' this increases productivity in the company and takes the strain off people.
Robots will support us in more and more areas in the future. It is therefore worthwhile to familiarize yourself with robotics as early as possible. Robots in school and training are therefore not only fun and loosen up the lessons, they also open up exciting prospects for future career choices.
