Safety Requirements for Collaborative Robots
Collaborative robots also referred to as cobots, are a modern-day approach to industrial robotic automation. In recent years, many industries have introduced collaborative robots in their warehouses for different functions, mainly because these cobots can work alongside humans safely.
A collaborative robot is an easy-to-use industrial assistant used to automate multiple processes in industries. This is all thanks to the intuitive software that comes built-in it.
Cobots are made with in-built features that make them safe to work alongside humans without needing to cage them. These safety features expand the range of jobs collaborative robots can do in a warehouse or industry. Collaborative robots can be relied upon to undertake complicated operations alongside human workers without posing a threat to their safety.
One of the best features of cobots is easy programmability. You can easily set the robot to switch from one task to another in the same work environment, meaning it can be used to perform a task process from beginning to end without needing human interference. This makes collaborative robots flexible and highly cost-effective for different industries.
These are the reasons more, and more industries are applying collaborative robots in their industrial processes.
Safety factors for collaborative robots
According to companies that manufacture collaborative robots, these human-friendly robots are created to be inherently safe to work around. The inbuilt safety features collaborative robots come with make them safer than traditional industrial robots.
ISO 10218 offers guidelines and information about robotic designs and manufacturing expectations. For a robot to be said to be collaborative, it needs to be able to perform its functions safely, whether or not there are human workers in proximity to the robotic arm.
The ISO 15066 gives further details and expectations for collaborative robots in line with current robotic technology.
Four major safety factors need to be achieved before a robot can be declared as collaborative. These include:
Hand guiding capabilities
This feature is required for programming, teaching, and cobots sequencing of the steps to follow for a task. Collaborative robots are required to have safeguards for hand guiding.
Hand guiding should be done when a robotic arm is stationary and after speed and force limit activation. The cobot operator needs to select hand guide mode for the process to be a success.
Safety monitoring stop
Collaborative robots are rewired to automatically come to a stop whenever human workers invade the cobot’s safety parameters. This ability to stop automatically is enabled by safety software that can also slow down the arm’s operations until the workspace is safe again.
This is an important aspect for any cobot as it makes it possible for them to function on the same floor as human workers.
Power and force limiting in cobots
Collaborative robots are required to include power and force limiting sensors that prevent possible collisions or force overload. They should also be designed with force dissipating round edges and sensors installed in the robotic arm joints.
Speed and separation monitoring
Collaborative robots must be made with motion sensors for tracking human workers' proximity to the robotic arm. This capability makes it possible to use collaborative robots in safety zones. This way, cobots reduce the working speed to accommodate the presence and participation of human workers for certain tasks.
With the ISO/TS 15066 guidelines, the risk of injury to human workers is reduced whenever there is contact between them and collaborative robots. This is one of the ways cobots beat traditional industrial robots.
Common collaborative robot sensors include:
- Grippers with tactile sensitivity allow the robotic arm to ‘feel’ on touch for grip adjustment
- Current feedback sensors
- Accelerometers to detect bumps and movement near the robotic arm
- Force torque sensors
- 3D vision cameras to detect the presence of objects
- Laser sensors action triggers
In many ways, the ISO safety guidelines, together with the inbuilt safety capabilities of cobots, make them completely safe to function alongside human workers.
For various commercial and industrial implementations, vision inspections systems offer image-based computerized inspection for your comfort. However, not modern tech, 2D and 3D machine vision technologies for computerized inspection, control engineering, top-notch management, and sorting are now frequently used, and so on.
With the increasing online fraud, identity verification becomes the need of all businesses. Different organizations are using identity authentication services to onboard their customers but they are still facing some problems as they use manual verification solutions.
There are many things that people want to know what to check if your furnace is not working. When the stove burns fuel, it produces hot air, and this hot air has to be released. A stove needs repairs because it has overheated and the wires inside of it have become burned.

LCD displays use pixels that are made of liquid organic material. The fantastic characteristic features of LCD displays have led it to be used for every purpose.
We are sure that when it comes to purchasing a LED TV, a lot of advice and guidance are thrown around. While it can be overwhelming at times to take everything in, it is important that you do not lose sight of what is important and pay attention to the basics.
From the convenience point of consideration, wireless printers for mac are the ideal options you should consider. You will get more benefits if your printer and mac device are already connected to reliable internet. Wireless printers are of great benefit because they can be connected to multiple Mac devices at the same time, without the need to use connecting wire.
For decades, the information technology (IT) department of a company was responsible for managing the hardware and software of the IT section. In recent times, there are several large clouds which have been distributed to several locations and are connected to central servers where the information is stored.
