Speed and Separation Monitoring in 2D: ISO/TS 15066 Cobot…

What Is Speed and Separation Monitoring?

Speed and separation monitoring (SSM) is a safety protocol designed to ensure that human workers are kept at a safe distance from robotic systems during operation. This system uses sensors to continuously measure the distance between the robot and any nearby humans, adjusting the robot's speed accordingly.

The goal of SSM is to prevent accidents by ensuring that the robot can stop or decelerate in time if it detects an approaching human worker.

How Does ISO/TS 15066 Define SSM?

ISO/TS 15066 provides a standardized approach to implementing SSM systems, ensuring consistency across different robotic applications. It defines the parameters that must be considered when setting up an SSM system, such as the minimum separation distance and the robot's maximum allowable speed.

The standard also outlines the requirements for sensors and control systems used in SSM, emphasizing the importance of real-time monitoring to maintain safety.

Real-World Applications of SSM

In practice, SSM is widely used in industries where human workers interact with robotic systems, such as manufacturing, healthcare, and logistics. For example, in automotive assembly lines, robots often need to move parts while humans work nearby.

By using SSM, these industries can ensure that their operations are both efficient and safe, reducing the risk of accidents and injuries.

Technical Details of SSM Implementation

Implementing an effective SSM system involves several technical considerations. Key factors include the choice of sensors (such as laser scanners or cameras) for distance measurement, the control algorithms that determine the robot's speed based on separation distance, and the reaction time of the system.

The ISO/TS 15066 standard also includes guidelines for testing and validating SSM systems to ensure they meet safety requirements.
