The Swiss company Gudel, known for its solutions in the field of linear displacement systems, has introduced a new development called Cobomover. This is a system that allows collaborative robots to move along the rails, significantly expanding their working area. Simply put, they taught robots to ride on rails — the solution is so obvious that it's amazing why they only thought of it now.

Cobomover is positioned as an ideal solution for tasks that require a large working radius, such as servicing large equipment or working on long production lines. The system allows robots to travel distances up to 100 meters with a positioning accuracy of 0.1 mm. Although, to be honest, it's hard to imagine a production task that would require such precision at a hundred—meter range, except for assembling spaceships right on the shop floor.

The developers paid special attention to safety — the system is equipped with numerous sensors and can stop when obstacles are detected. This is especially important given that the robot moving along the rails is a cross between an industrial manipulator and a miniature train. Although it is unlikely that anyone will voluntarily stand in the way of this design - even the most curious employee is unlikely to want to experience the impact force of a moving robot.

Interestingly, the system is compatible with most popular models of collaborative robots, which allows enterprises to modernize existing lines without completely replacing equipment. Although the question arises: if the company already has robots, why do they also need a rail track? Wouldn't it be easier to buy one larger robot? But apparently, the Swiss think otherwise.

The economic component is also of interest. The cost of the system is quite comparable to the price of an additional robot, while it requires the installation of rails — which obviously will not add flexibility to the production process. It seems that the developers assume that enterprises are willing to sacrifice mobility in order to increase the work area.

Critics may notice that the system looks like a step back to the days when robots were tied to one place. But the developers retort: their solution allows robots to work where it is really needed, and not where the length of the cables allows.

However, it is impossible not to recognize a certain elegance of the solution. Instead of creating a complex and expensive robot with a long range, they simply gave existing models the ability to move around. It's like the story of the invention of the wheel — sometimes the simplest solutions turn out to be the most effective.

We can only hope that production workers will not start using the rails to ride wheelbarrows with tools — although who knows, maybe this will be the next stage in the development of the system.
