EOAS – SAFETY SYSTEMS FOR ROBOTS

Safeguard your collaborative application with the world’s first contactless safety solution for robot end-effectors and workpieces using SICK’s End-of-Arm-Safeguard (EOAS). Designed to facilitate interaction with the robot, the EOAS offers safeguarding in conjunction with UR collaborative robots. Now more than ever, safety is a priority in robotic applications. Whether it is pick place, handling assembly, or machine tending applications, the EOAS enables safe interaction with automatic restart. Create more freedom for human and machine with a protective field around the end-of-arm-tooling (EOAT). The protective field moves with the robot and is always where needed. This opens new spaces for human and machine that can be used freely and productively. With deep integration into the UR-eco-system and a URCap available, easily install the system within 15 minutes! Increase the speed and productivity of your human robot collaboration application knowing the EOAS will keep you safe. While thinking safety, consider using SICK’s End-of-Arm-Safeguard for your next Universal Robots collaborative application!

The EOAS generates a protective field around gripper and workpiece to prevent the robot from hitting any object outside of its normal operation. The local protective field moves with the robot arm and reacts dynamically depending on the current position. There is a muting mode for faster working areas of the robot if need be. Configure the EOAS entirely via a URCap with a 3-step process. Determine ””process points”” so the normal environment can be taught to the sensor. Mount the sensor directly on the robot flange and connect via 2 cables with M12. The EOAS provides contactless and reliable Time of Flight (ToF) technology.

Collision-free collaboration: Worker acceptance and trust in the robot, as End-of-Arm Safeguard stops robot movement before crushing occurs.

Efficient safety validation: The effort required for force and pressure measurements in accordance with ISO/TS
15066 is significantly reduced, as the end-ofarm safeguard prevents crushing with the gripper or workpiece.

Faster cobot, higher productivity: Contactless safeguarding of tool and workpiece area allows to increase the speed of the robot in collaborative deployments.

Free-up workspaces: The protective field moves with the robot arm and is always where it is needed. This makes it possible to optimize the use of space and increase operator efficiency.

Seamless installation and configuration: End-of-Arm-Safeguard is deeply integrated into the UR ecosystem and can be installed and configured within 15 minutes. Daily operation is possible even without expert knowledge.

 

EOAS Sensor

The EOAS Sensor is mounted between robot tool flange and robot tool. It is directly connected to the
robot controller.
The EOAS Sensor creates a cone shaped protective field surrounding robot tool and workpiece.

 

EOAS URCap

Installed on the robot controller, the EOAS URCap software receives the EOAS Sensor data. EOAS The URCap combines it with safety rated robot data and derives all required safety actions.
Upon protection field violations, the EOAS system slows down or stops the robot movement, preventing crushing situations with the robot tool or workpieces handled.
