Speed and separation monitoring with SICK’s sBot safety system and URCap for Universal Robots

23 March 2021

SICK and Universal Robots (UR) have unveiled a new safety solution for the safeguarding of accessible robotic applications. When combined, the sBot safety system and URCap from SICK increase productivity with immediate automated restart and profit from an easy configuration of the safety system directly from the UR teach pendant.

With this partnership, SICK and UR have created the fastest way to implement speed and separation monitoring for cooperative robot applications.

The sBot Stop – URCap and sBot Speed – URCap are easy-to-use safety systems based on the smart Source: SICKSource: SICKcombination of the nanoScan3 safety laser scanner and UR Robot safety features. These solutions work well in handling operations using robot applications with free access and enable manufacturers to achieve safety without sacrificing productivity.

Intelligent safety for robotics with nanoScan3

The nanoScan3 is the world’s smallest profile safety laser scanner. Its space-saving design works perfectly in mobile robotics applications, but also in stationary applications where space is limited. It delivers high-precision measurement data and is extremely resistant to light, dust or dirt. It also has the highest level of flexibility with up to 128 freely configurable fields and monitoring cases.

The nanoScan3 Core safety laser scanner is smartly combined with the URe robot safety features thanks to a provided configuration tool. This enables the easy configuration directly via the UR teach pendant.

The safety laser scanner is constantly monitoring the ground level around the robot. A nanoScan3 Pro is able to monitor with two protective fields simultaneously the area around the robot, this makes it possible to dynamically reduce or stop the robot movement only when a person is too close from the robot working area. As soon as the person leaves the area, the robot recovers its operating speed and becomes productive yet again. With the nanoScan3, it can achieve a high safety performance level – PLd.

Easy safeguarding of free accessible robot applications

The sBot Stop – URCap and sBot Speed – URCap are safety systems for the safeguarding of free accessible robot applications with the highlight of a fast and easy configuration of up to two safety laser scanner(s) directly via the UR teach pendant. Using the sBot Speed – URCap safety system, the access to the robot is free and the robot will reduce the speed and, if necessary, stop when a detected person gets too close to the robot working area. The sBot Stop – URCap safety system provides customers with the ability to output a warning if a person gets close to the application and, if necessary, stop when a detected person gets too close to the robot working area. With both systems, the robot will resume its activities at full operational speed as soon as the person leaves this area, providing customers with the highest productivity.

Additionally, sBot Stop – URCap and sBot Speed – URCap offer a new way of safeguarding robot applications and achieving high productivity. It is easy and fast to set up and offers smart features like smart field definition, field teach-in, simultaneous scan data and automatic field fusion provides feedback through the GUI. This eases the setup, diagnostics, commissioning and validation.
