Cobots: the intelligent robot as a colleague
Cobots transform manufacturing plants into smart factories. KUKA already developed the world’s first cobot – the LBR iiwa – back in 2014 and is setting new standards with the new LBR iisy. They take on work steps that are strenuous, monotonous or dangerous for humans. In this way, the collaborative robot optimizes processes and boosts productivity.
Cobots vs. robots: What exactly are cobots?
Cobots are collaborative or collaborating robots that, unlike conventional industrial robots, can work together with humans in the same workspace without safeguards. Sensors and cameras on the cobot guarantee that the robot will never injure its human colleagues. Conventional industrial robots, on the other hand, require safety fences and other safety precautions.
The HRC-enabled industrial robot is now a machine that humans can touch and interact with. Human workers and cobots safely share the same workspace. In this way, companies can save on costly feed systems and production space. When people and robots work together, conventional safety precautions become superfluous. In the event of unexpected contact, for example, collaborating robots reduce their speed and thus also their kinetic energy. Additional costs which would normally be required for safety equipment and protective fences are thus avoided. Where there are no fences restricting space for working, the way is clear for new, highly efficient and far more flexible tasks: from industrial work assistants to service robots in public spaces, and from nursing robots in clinical environments to domestic assistants.
KUKA cobots: industrial applications
Dangerous overhead applications, monotonous and repetitive processes, or meticulously detailed work: cobots perform these work steps, relieve employees and deliver consistently high quality. With their integrated sensors, the collaborative robots enable assembly tasks featuring small parts to be automated – they assemble automotive transmissions, insert rubber plugs or process non-rigid parts. Their human colleagues can thus concentrate on other segments of their work. While the cobot is processing a part, the worker can already prepare the next production step. The sensitive robots respond intelligently to their environment and move independently. This is referred to as human-robot collaboration (HRC) or collaborative robotics. Intelligent cobots are opening up new areas of automation: they load machines or logistics systems, build industrial robots themselves and much more besides.
The KUKA LBR iiwa cobot: AI in production
As a pioneer in the field of cobots, KUKA already laid the foundation for a new relationship between humans and industrial robots in Production 4.0 back in 2014 with the LBR iiwa. As a component of the smart factory, the lightweight robot iiwa is able to learn from its human colleagues thanks to its sensitive technology. Connected to a cloud and specially programmed, this cobot can also independently document, check and optimize the results of its work.
Collaborative robotics in action: body-in-white production at Ford with four LBR iiwa robots
At Ford, humans and machines work hand in hand. The task involved here is applying a sealant seam – a monotonous, strenuous and dirty work process. An unpleasant job for humans, it does not bother the collaborating robot: the worker programs the robot once by means of manual control. The smart machine then executes the motion sequence independently – quickly, precisely and efficiently.
Cobots as a success factor: “Our employees can now focus on a fluid work sequence,” says Ford Production Engineer Michael Koch.
The LBR iisy cobot sets new standards
The new LBR iisy is ready for operation in just a few minutes and, thanks to the iiQKA.OS operating system, can be intuitively controlled. The cobot can also be used in a wide range of production areas and taught by means of simple manual guidance, so no prior knowledge of programming collaborative robots is required. The LBR iisy is particularly suitable for the loading and unloading of machines, as well as the handling of small parts, pick-and-place tasks, and packaging and testing applications. When it comes to deploying the LBR iisy, therefore, the sky’s the limit.

The KMR iiwa (KUKA Mobile Robotics) combines the advantages of the LBR iiwa with a mobile and flexible platform. The mobile robot thus enjoys great flexibility and can be easily integrated into a wide variety of manufacturing processes. The mobility of the cobot enables maximum maneuverability and can decisively optimize production processes. The HRC-capable mobile robot is equipped with Mecanum wheels and is thus extremely flexible. In the cleanroom version, it guarantees the safe transfer and also the safe handling of sensitive components (wafers, masks, carriers) from one process to the next. It navigates in all directions autonomously and without safety fencing.
LBR Med: a collaborative robot for medical applications
Particularly in the field of medical technology, precise work is essential. With the KUKA LBR Med cobot, physicians and medical staff have a reliable colleague at hand.
The sensitive seven-axis lightweight robot can be used for everything from diagnostics and treatment to surgical procedures. It can be found wherever strenuous, repetitive, tiring activities or particular precision are required.
Nursing staff also use the cobot in rehabilitation. Rehabilitation robot ROBERT® gets patients re-accustomed to moving after operations, thereby relieving nursing staff, both physically and mentally.

Advantages of HRC robots in industry
Efficient division of labor:
Human and robot perfectly complement one another. While the cobot performs strenuous and monotonous tasks, the worker prepares the next steps, checks the results and organizes the process to ensure that it runs efficiently.
The collaborating robot safely and quickly performs the tasks that are dangerous or unpleasant for humans. The cobot also ensures error-free performance of work that requires a high level of concentration over a prolonged period of time.
The intelligent robots are ideally networked with one another. They learn to perform the work steps together efficiently. This is how intelligent manufacturing with cobots works (smart production).
High manufacturing quality:
A robot works precisely, quickly and without breaks. Furthermore, a cobot can work intelligently, learning and optimizing successive work steps. This results in higher product quality.
