Industrial Robots Vs (or With?) Cobots
Article by | Elite robots
Since the early 1960s, manufacturers have been using industrial robots to automate their manufacturing processes. Nevertheless, along the way, while bringing an undeniable gain in productivity, industrial robots have also gradually shown several limits and weak points.
In addition to being dangerous for workers, and therefore requiring specific safety measures in their work area, industrial robots are also extremely expensive and difficult to install and redeploy, which often makes them an expensive investment, in especially for SMEs.
Thus, cobots, a new generation of robots, quickly made their way into the manufacturing industry and reshaped the whole robotics world. Cobots are more economical, more ergonomic, quick to set up and redeploy, and can work alongside humans without the need for protective fencing.
Despite this, industrial robots remain indispensable for certain specific tasks, for example when they require high payloads, very high speed or extreme precision. In such cases, manufacturers must still necessarily turn to industrial robots for their automation needs.
However, cobots can still be deployed for other related processing tasks, also within the same production cycle, giving rise to an almost “complementary” relationship between industrial and collaborative robots.
The photo below taken in a car factory clearly shows this relationship: while the industrial robot with high payload is in charge of loading and unloading the central console of cars, the collaborative robot EC66 ELITE ROBOTS works at the same workstation for screwing.
The flexibility offered by the Elite Robots cobot allowed the end user to seamlessly integrate it into their original workstation and extend it, without needing to change its layout, thus making the automation process more compact and simpler.
Another case study, also from the automotive industry, further highlights this complementary relationship.
As we can see, one of our cobots, this time EC612, was even integrated into an industrial robot flange plate, itself acting as an EoAT.
This application highlights some of the main advantages of Elite Robots’ cobots, mainly its excellent strength-to-weight ratio. Its lightweight design allowed for seamless integration with the industrial robot, which can effortlessly lift the EC612 and use it to paint the interior body of a bus.
In this case, although standardized painting robots can also perform this processing task, there are also other factors to consider which led the user to choose our EC612 cobot.
1. Flexibility and security.
Deploying huge and heavy equipment in this workstation can take up a lot of space and require the user to change the layout of their existing production line, which is a major deterrent for many manufacturers.
On the other hand, and as we saw in the previous application, Elite Robots EC12 easily managed to solve the user’s problems without forcing him to disrupt his production line, taking up very little space and making the work area safer for operators.
2. Easy programming.
Since the body of public buses is not as well decorated as the interior of passenger cars, painting does not require a very high level of precision that only industrial robots can provide. On the contrary, our cobot can perfectly handle this task by simple trajectory planning.
3. Large distance to cover.
Although in this application the required payload is low, the EC612 was chosen due to the large distance to be covered in the work area by the robotic arm, which as we can see is in its maximum extension ( 1304mm). In similar applications, but with a greater payload, another advantage represented by the EC612 is undoubtedly the high level of resistance ensured by the cobot even at its maximum extension.
