Risk assessment is a crucial step in ensuring the safe operation of collaborative robots. It involves the systematic identification and analysis of hazards associated with their use.
Conducting a thorough risk assessment, organizations can identify potential dangers and implement appropriate control measures to mitigate them.
This article focuses on the importance of collaborative robot risk assessment and introduces a template to aid this process.
The template provides a structured approach for hazard identification and analysis, enabling organizations to assess the risks associated with collaborative robots comprehensively.
Following this template, businesses can ensure the safe integration of cobots into their operations while minimizing the likelihood of accidents or injuries.
Adopting a robust risk assessment methodology is essential for safely harnessing the benefits of collaborative robots in diverse industrial settings.
What is a Collaborative Robot?
Assessing risks with collaborative robots is an important aspect of ensuring the safety and effectiveness of these advanced machines.
Collaborative robots, also known as cobots, are designed to work alongside humans in a shared workspace, and this proximity can introduce unique risks that need to be carefully evaluated.
As a Robot Integrator, you play a pivotal role in applying industrial robotics. With your expertise, the tasks of robots, from mobile industrial robots to standard robots, become a seamless part of the workflow.
Whether it’s manipulating the robot’s wrist or managing the robot cycle, your responsibilities are vast and varied.
It’s about understanding the current robot in use, future robot control development, and the potential of collaborative robot applications.
Standards such as 10218-2:2011 – Robots, 4ISO/TS 15066 – Robots, 8SS-EN ISO 10218-1:2011 – Robots, and ANSI/RIA R15.06-2012 Robot Safety Standard guide the design and safety protocols for facilities with robot systems.
These principles for design also encompass complex product design and design requirements for robot features and application requirements. The safety of nearby workers, worker interaction, and the compatibility of human workers with robots are all integral parts of this process.
Understanding the operating space is another essential part of a robot application integrator’s job, whether determining the maximum space, restricted space, or the volume of space encompassing the self-propelled and self-contained robot.
It’s all about ensuring an efficient and safe robot work cell. The presence of various hazards, such as thermal, electrical, or hazardous sources. These must be assessed during automatic operations like arc welding or assembly operations.
External devices, from accessory devices, 3-position enabling devices, limiting devices, and portable control devices, all play a significant role in the safe operation of robots.
Safety considerations also extend to cobot manufacturers and their ancillary equipment. Ensuring the right risk reduction and safeguarding level is crucial to maintain an acceptable level of safety.
Assessing tasks, including additional tasks that may arise from integrating new technologies or operations, forms a crucial part of the risk assessment process. Particular attention must be given to the arm of cobots, as it often interacts directly with worker operators.
The contact pressure during this interaction, pressure testing, and managing the hazard combination should be incorporated into a clear, easy-to-understand, consistent methodology, such as the Task-based Risk Assessment Methodology.
Documentation plays a significant role in this process. Documenting risk and decisions made and maintaining an all-inclusive document for reference is crucial for maintaining transparency and ensuring continuous improvement.
This documentation also helps facilitate the design risk assessment stage and guides organizations such as Design Safety Engineering Inc.
Administrative safeguards and Organizational measures are vital aspects of managing risk. Tools like the Tool Center Point and external tools, depending on the cobot model, come into play in ensuring the safety of Numerically Controlled Machine Tools.
Whether in manual mode or automatic, these measures help manage the source of control and potential application-related sources of risk.
In conclusion, a Robot Integrator is crucial in managing and implementing robot systems.
From the standard robot to the most complex cobot, their job involves a wide variety of tasks, ensuring the safety and efficiency of the workplace while enabling the exciting future of industrial automation.
Conducting a thorough risk assessment, organizations can identify potential hazards and implement appropriate mitigation strategies to protect human workers and collaborative robots.
