In the age of advanced automation, industrial robots have become indispensable players within production facilities. Their efficiency, precision, and ability to operate continuously are highly valued. Yet, with their growing presence comes a crucial responsibility: ensuring the safety of human operators who interact with these machines.
Protecting robots and robotic cells is not merely about adhering to regulations—it’s about safeguarding human integrity and enhancing productivity.
A solid safety strategy begins with a comprehensive risk assessment. This crucial step identifies potential hazards throughout every phase of robotic operation, from start-up and standard use to shutdowns and unforeseen malfunctions. The evaluation must consider the robot’s range of motion, speed, attached tools (such as grippers, welders, or blades), human access zones, entrapment risks, and any other factor that may compromise safety.
A recommended approach involves following ISO 12100, a standard that outlines general principles for safe design, risk identification, and mitigation measures. This framework also serves as the foundation for defining the required Performance Level (PLr) under ISO 13849-1, which is essential for calculating the reliability of implemented safety functions.
Robotics safety is governed by a set of international technical standards that manufacturers and integrators must observe. Among the most relevant:
- ISO 10218-1 and 10218-2 – which define safety requirements for industrial robots and their integration into automated systems.
- ISO/TS 15066 – providing specific guidelines for collaborative robots (cobots), where human contact is intentional or permitted.
- ANSI/RIA R15.06 (U.S.) – the leading North American standard for safe robotic system design and implementation, aligned with ISO guidelines.
In practice, there are many technologies and devices designed to protect both personnel and robots:
- Safety fences with interlocked gates
- Light curtains and laser scanners that halt operations if a protected zone is crossed
- Easily accessible emergency stop systems
- Virtual safety zones programmed via software to define work areas and automatically reduce speed when humans are present
- Collaborative robots built with force sensors and advanced control systems for safe interaction
Technology alone, however, isn’t enough. Ongoing training for technical and operational staff is vital in preventing accidents. It’s important that all employees understand safety protocols, emergency procedures, and maintenance best practices. Moreover, fostering a strong safety culture within the organization helps identify flaws or risky behaviors before they lead to actual hazards. Effective communication between engineers, operators, and safety managers is essential.
Ultimately, safeguarding robots and robotic cells goes beyond regulatory compliance—it’s a strategic investment. Implementing the right safety measures not only prevents injuries and downtime but also reinforces trust in automation technologies. Through rigorous risk assessments, regulatory alignment, advanced protective solutions, and continuous training, companies can build safer, more efficient, and truly sustainable automated environments.
