Introduction of the End of Arm Safeguard (EOAS)

SICK has introduced its innovative End of Arm Safeguard (EOAS) designed for collaborative robots (cobots). This pioneering solution sets a new standard for safe and seamless interaction between robots and human operators, enhancing workplace safety in industrial automation environments.

Collaboration with Universal Robots

In partnership with Universal Robots, the leading manufacturer of cobots, SICK combines its extensive expertise in sensor technology with cutting-edge robotic innovations. The EOAS mounts directly onto the cobot’s arm, allowing for dynamic movement and ensuring reliable, contactless collaboration between robots and human workers.

The First Contactless Safety Solution

The EOAS represents a significant advance in safety measures for collaborative applications. As a category 2 laser device (ISO 13849), it establishes a secure protective field around the robot's end tool. This feature permits the cobot to maneuver within confined spaces while maintaining a fixed hazard range of up to 400mm. If a human inadvertently enters this protective zone, the EOAS triggers an immediate stop, ensuring worker safety.

Enhancing Dynamic Responses with Time-of-Flight Technology

SICK has integrated time-of-flight technology into the EOAS, enabling quick reactions from the robotic arm with a response time of less than 110 milliseconds. This swift response enhances production speed while ensuring a safe environment for human workers, who can collaborate confidently knowing that the robot will stop when the protective field is breached and resume once it is restored.

Quick Installation and User-Friendly Operation

The EOAS features a plug-and-play setup, allowing swift installation within just 15 minutes. It is compatible with Universal Robots' robotic systems and is recognized as an accessory by the robot’s interface. Additionally, EOAS URCap software simplifies integration with existing operations, while ongoing tutorials ensure effective deployment.

Safety with the Safeguard Stop

The EOAS establishes a Safeguard Stop through an invisible protective field formed by 40 infrared laser beams. This field envelops the tool and workpiece, permitting close human interaction with the cobot while maximizing safety. By attaching the sensor directly to the robot arm, the EOAS minimizes unnecessary stops, enhancing both productivity and worker safety when handling workpieces.

Versatile Applications Across Industries

The EOAS is suitable for a wide array of applications, including pick and place tasks, machine tending, and assembly operations. Industries such as pharmaceuticals, electronics, food and beverage, automotive, and packaging can greatly benefit from implementing this advanced safety solution.

Expertise and Development Insights

Matthew van den Braak, Product Manager for Robotic & Mobile Platforms at SICK UK, notes, “The EOAS is designed to maximize worker safety in collaborative environments. Its ease of installation and configuration makes it a game changer.” The collaboration with Universal Robots not only facilitated robust field testing but also ensured that the EOAS meets high industry safety standards.

David Lievesley, a Technical Support Engineer at Universal Robots, highlights the EOAS's patented technology, which operates seamlessly within its safety system. He states, “Adjusting the sensor parameters also updates the robot settings, fostering effective human-robot collaboration in compact environments.”

Conclusion: Leading the Future of Collaborative Robotics

The introduction of the EOAS solidifies SICK and Universal Robots' commitment to advancing safety in industrial automation. This innovative solution supports efficient, collaborative operations without compromising worker safety. As industries continue adopting cobots, effective safety measures like the EOAS will be crucial for achieving optimal operational efficiency.
