In today’s rapidly evolving manufacturing industry, the use of industrial robots has become increasingly common. These advanced machines, equipped with state-of-the-art technology and programmed to perform complex tasks, have revolutionised production lines and achieved greater efficiency and productivity. However, as the presence of robots in manufacturing facilities grows, ensuring worker safety becomes a critical concern.
The importance of safety in robotic applications
Robotic systems are designed to automate repetitive tasks traditionally performed by humans. Their high-speed operation and precision significantly improve productivity while reducing errors on assembly lines or within various manufacturing processes.
However, despite their many advantages, industrial robots pose potential risks to human workers if proper safety precautions are not taken. These risks include collisions between humans and robots or their moving parts, unintentional movements leading to crushing injuries or entrapment incidents.
Protecting workers through risk assessment
To ensure the safety of workers when working with industrial robots within a production line or any other environment where human-robot collaboration occurs, it is essential to conduct comprehensive risk assessments beforehand. This process involves identifying potential hazards associated with robotic operations and determining the precautionary measures necessary to effectively mitigate these risks.
Leading robotics manufacturers such as KUKA Robotics Corp., ABB Ltd., Fanuc Corporation, Yaskawa Electric Corporation (Motoman), among others, prioritise providing safe solutions for automated robotic applications. They continuously invest resources in research and development efforts aimed at improving robot functionality while ensuring maximum worker safety.
The role of collaborative robots (cobots)
A notable development in the field of robotics is the introduction of collaborative robots (cobots). Unlike traditional industrial robots, cobots are specifically designed to work safely in close proximity or collaboration with human workers. They incorporate advanced safety features such as force and speed limitations and the ability to detect human presence through sensors.

Collaborative robots have revolutionised manufacturing processes by enabling direct human-machine interaction without the need for large guards or fences. This not only reduces production costs but also improves flexibility in reconfiguring workstations according to changing requirements.
Key safety measures for working with industrial robots
To ensure the safety of workers when working with industrial robots, companies must implement specific measures that align with established industry standards. The following are some crucial safety practices:
– Risk assessment: conduct thorough risk assessments before implementing robotic systems to identify potential hazards and develop appropriate countermeasures.
– Safety training: provide comprehensive training programmes for workers on safe robot operation, emergency shutdown procedures, and effective handling of unexpected situations.
– Physical barriers/cages: Install physical barriers or cages around robotic equipment to prevent unauthorised access during operation while ensuring adequate visibility to monitor workflows.
– Sensors/Security Systems: Equip robots with advanced sensors (e.g. laser scanners) capable of detecting human presence in their vicinity. Implement integrated control systems that can stop operations instantly if potential danger is detected.

The continuous advancement of robot safety technologies
The field of robotics is continually evolving along with technological advances. Manufacturers are constantly striving to improve existing safety features while introducing new ones that push the boundaries of worker-robot collaboration even further. These innovations include improved collision detection algorithms, enhanced sensor technologies and artificial intelligence-based motion tracking systems, among others, all aimed at achieving an optimal balance between productivity and safety.
In the field of industrial automation, worker safety remains a primary concern. As the use of industrial robots becomes more prevalent in manufacturing processes, it is crucial to implement comprehensive safety measures to protect workers from potential risks. Conducting thorough risk assessments, using collaborative robotic solutions and implementing sound safety practices collectively help ensure a safe working environment where human workers can operate alongside advanced robotic systems effectively and efficiently.
