A collaborative robot is a robot intended for direct human robot interaction within a shared workspace, or where humans and robots are in close proximity. For safety reasons, they are typically run at reduced speed with respect to traditional industrial robots. On the other hand, the persistent presence of the human worker might introduce several benefits in specific applications. The activation of safety mechanisms usually stops the motion of these robots or reduces their productivity, as well as the one of other machines and robots involved in the same production process. With the aim of improving their productivity with respect to these situations, we have proposed an online trajectory optimisation method for collaborative robots capable of reducing the number of interventions of safety functionalities.Continue reading “An IIoT solution to speed-up collaborative robotics applications”
Collaborative robotics: a new paradigm?
Collaborative robotics has now been a reality for about ten years and finds space in various applications ranging from the loading of machine tools to quality control, passing through end-of-line packaging.
The ease of installation and the rapid return on investment have represented the main growth drivers of this technology which is carving out an increasing role in the wider robotics sector.
According to the Statistics Department of the International Federation of Robotics (IFR), collaborative robotics installations represent a constantly growing market share, from 2.8% in 2017 to 4.8% in 2019. This occurs mainly in new markets and for new applications and minimally subtracting quotas from more traditional robotics.
When robots can decide what to do
The word “cobot” denotes a robot optimised for the collaboration with humans. Traditional industrial robotics guarantees high efficiency and repeatability for mass production but it lacks flexibility to deal with the fast changes in the consumers’ demand. Humans, on the other hand, can face such uncertainties and variability but they are limited by their physical capabilities, in terms of repeatability, physical strength, endurance, speed etc. The human-robot collaboration is a productive balance that catches the benefits from both industrial automation and human work.Continue reading “When robots can decide what to do”
Robotics gives humans some relief
One of the benefits arising from the adoption of collaborative robots is the possibility to share or carry the load during transportation or manipulation. This type of collaborative operation can clearly reduce the muscular effort of the human, and possibly increase the quality of working environment.
Musculoskeletal disorders (MSDs), in fact, represent one of the major work-related health problem in developed countries, affecting almost 50% of industrial workers. As MSDs are mainly due to strenuous biomechanical solicitations due, e.g. to payload transportation or bad postures, it is widely agreed that collaborative robots can help in preserving employees’ health by taking up physically demanding tasks which are too complex to be fully automated.
Industry 4.0: towards an intelligent collaboration with robots
How many times, at the grocery shop, while waiting for our turn to be served we naturally asked ourselves: should I just queue and wait or should I swing by another aisle in the meanwhile? Well… just a simple question that however entails quite a few reasoning: how fast are the attendants in serving other people? how much time do I have without loosing my turn?
Now, let’s virtually move this paradigm to the factory of the future. Our guest star is now a collaborative robot that has to decide when the human fellow co-worker will require its assistance.Continue reading “Industry 4.0: towards an intelligent collaboration with robots”
