How do collaborative robots ensure safety during operation? Collaborative Robot
In the modern industrial landscape, collaborative robots, often referred to as cobots, have emerged as game – changers. As a leading supplier of collaborative robots, I’ve witnessed firsthand how these remarkable machines have transformed the way businesses operate. One of the most pressing questions that comes up time and again is about safety during operation. How do these cobots ensure that they can work side – by – side with human workers without causing harm?
Intrinsic Design Features for Safety
One of the fundamental ways collaborative robots ensure safety is through their intrinsic design. Unlike traditional industrial robots that are often large, powerful, and fenced off, cobots are built with safety at the core.
The first aspect is their lightweight construction. Cobots are generally made of lightweight materials, which reduces the potential force of impact in case of an accidental collision. For example, many of the cobots we supply are constructed with high – strength yet lightweight polymers and metals. This not only makes them more mobile but also minimizes the risk of serious injury if they come into contact with a human operator.
Another crucial design feature is the torque – sensing technology. These sensors are built into the joints of the cobot. They constantly monitor the amount of force being exerted by each joint. If the force exceeds a pre – set safety limit, the cobot will immediately stop its movement. This is a very important safety mechanism as it can prevent the cobot from causing any harm to a human worker who may accidentally get in its way. For instance, in a pick – and – place application in a manufacturing facility, if a worker’s hand unexpectedly enters the cobot’s workspace, the torque sensors will detect the sudden change in force, and the cobot will halt instantly.
Safety – rated Software and Programming
The software that controls collaborative robots plays a vital role in ensuring safety. Our cobots come with safety – rated software that has multiple layers of protection.
One of the key features of this software is the safety – rated speed and separation monitoring. The software allows operators to define a safety zone around the cobot. If a human worker enters this zone, the cobot will automatically slow down or stop depending on the distance. This is similar to how a car with automatic emergency braking might slow down when it detects an object in its path. In a warehouse setting, for example, where cobots are used for inventory management, the software can keep track of the position of human workers and adjust the cobot’s movement accordingly.
In addition, the programming of cobots also includes collision detection algorithms. These algorithms are designed to anticipate possible collisions and take preventive actions. They analyze the movement patterns of the cobot and the surrounding environment in real – time. If there is a high probability of a collision, the cobot will either change its path or stop. This is extremely useful in dynamic work environments where there are many moving objects and human workers.
Operator Training and Safety Protocols
While the design and software of cobots contribute significantly to safety, proper operator training and safety protocols are also essential.
We provide comprehensive training programs for all our customers who purchase our cobots. These training programs cover everything from the basic operation of the cobot to advanced safety procedures. Operators learn how to set up the cobot correctly, how to program it for different tasks, and most importantly, how to identify and respond to potential safety hazards.
In addition to operator training, we also help our customers develop detailed safety protocols. These protocols outline the proper use of the cobot, including what to do in case of an emergency. For example, the protocols might specify that all operators should wear appropriate safety gear, such as safety glasses and gloves. They also define the procedures for shutting down the cobot in an emergency and for conducting regular maintenance to ensure its continued safe operation.
Safety from a Regulatory Perspective
In the field of collaborative robots, safety is closely regulated by various international and national standards. Our cobots are designed and manufactured to comply with all the relevant safety standards, such as ISO 10218 and ISO/TS 15066.
These standards set out strict requirements for the design, construction, and operation of cobots. For example, ISO/TS 15066 provides specific guidelines on the maximum allowable forces and torques that cobots can exert during operation. By adhering to these standards, we ensure that our cobots are not only safe but also meet the legal requirements of different countries. This gives our customers the confidence that they are using a product that has been rigorously tested and approved for safety.
Case Studies: Real – World Safety in Action
Let’s look at some real – world examples of how our collaborative robots ensure safety during operation.
In a food manufacturing plant, our cobots are used for packaging tasks. The cobots work alongside human workers, picking up food products from the conveyor belt and placing them into packages. Thanks to the torque – sensing technology and speed and separation monitoring, the cobots are able to work safely in the same workspace as the human workers. If a worker’s hand comes too close, the cobot will either slow down or stop, preventing any potential injuries.
In an electronics assembly line, our cobots are programmed to perform delicate soldering tasks. The collision detection algorithms in the cobot’s software ensure that the cobot does not collide with the expensive electronic components on the assembly line. This not only protects the components but also the human workers who are responsible for loading and unloading the parts.
Conclusion
In conclusion, as a leading supplier of collaborative robots, we are committed to ensuring that our products are as safe as possible during operation. Through intrinsic design features, safety – rated software and programming, operator training and safety protocols, and compliance with regulatory standards, our cobots are able to work safely alongside human workers.
