With the EOAS, when the protective field
is breached, a Safe Stop is triggered and the cobot immediately ceases movement, recommencing its task once it is restored. Lights on the EOAS indicate clearly when it has stopped and when it is moving. Furthermore, time-of-flight technology provides a response
time of 110 ms, speeding up productivity while maintaining safe operation. Creating a protective field around the
robot tool at the end of the robot arm, the EOAS moves with the arm and operates in a much smaller, more defined area than previous products, to protect a fixed hazard range of up to 400mm. Mark Stephenson, divisionalmanager at
WMH Robotics, said: “The EOAS will result in a lower number of false triggers and false Safe Stops. It won’t stop until you are at the point where it is potentially hazardous.” One of the key benefits of the EOAS is the
closely and efficiently alongside cobots by protecting the end effector, potentially without the need for mechanical or light guards, significantly reduces the safe zone of the cobot and therefore the overall footprint, length and cost of projects.
potential to remove additional safety measures for applications, such as physical guards. The EOAS provides a Safeguard Stop through an invisible, infrared, protective shell of 40 laser beams that covers the tool and workpiece to facilitate space- free operation. Allowing humans to work more
The EOAS can be installed in just 15 minutes
and the sensor is automatically recognised by Universal Robots technology. Stephenson added: “The EOAS makes the
operation status of the cobot clear; it’s either red or green. It has been developed as a true partnership between SICK and Universal Robots, with all the benefits of both companies. We will see cobots working collaboratively as they were intended to; making people more confident about getting closer to the machine and being more interactive with it for safe productivity.” There are a wide range of potential
markets and applications for the EOAS, in sectors ranging from pharmaceuticals and electronics, to food & beverage and automotive. Ideal for machine tending and pick and place applications such as presenting components to operators for assembly or where there’s multiple picks of parts, the EOAS can also be installed on a collaborative robot arm that is mounted on a mobile robot, reducing the number
of false stops for the robotic arm and creating greater flexibility within industrial settings.
