SAFETY COMPLIANT MOBILE ROBOTS
I
DEC’s newly launched Safety Wheel Drive (SWD) enables the user to robotise a rolling machine, such as an AGV or AMR, with only three safety devices: Two SWD wheels and one safety laser scanner. As a result, the engineering
effort that goes into developing a safety compliant mobile robot has been reduced dramatically, while development costs have been cut by a factor of five. Of further benefit, the absence of bulky components offers complete freedom for the robot layout and shape.
FEATURES
Each SWD wheel is equipped with a certified safety controller that processes information from the robot’s safety sensors to prevent unsafe movements. The built-in operational compliance to ISO 3691-4 (driverless truck standard) means safety
features within the wheel include STO (Safety Torque Off), SLS (Safe Limited Speed), SMS (Safe Maximum Speed), SBC (Safe Brake Control) and SDI (Safe Direction Control). It also offers direct compatibility with all SIL2/PLd safety laser scanners, such as the IDEC SE2L series. According to the company, the drives can be easily chained together to provide multi- wheel or multi-axis systems capable of moving several tons. SWD drives feature standard CANopen CiA/DS 402 interfaces for motor control, and safety loops ready to connect to the safety sensors.

At a press conference earlier this month, IDEC launched the Safety Wheel
Drive (SWD) which, it claims, gives designers of robotic solutions complete freedom to be creative
SAFETY The safety features mentioned previously are pre-configured within the SWD control and safety routines, which are usually complex and costly to develop. However, individual adjustments to suit the specific application can be carried out through a number of SWD support and configuration tools. In fact the SWD family are all configurable and provided with full drivers for both ROS and ROS2 (Robot Operating System) instruction sets, giving freedom to the developer. According to the company, you can choose
from the SWDCore (gear motor), the SWD125 (125mm diameter wheel) or the SWD150 (150mm diameter wheel). Each drive is sealed to IP66 (electronic housing) and available with various gear ratios, ensuring appropriate torque is available to move the required load. Applications for the SWDCore include pallet
THE SICK W10 SWIPE-AND-SET-UP TOUCHSCREEN SENSOR IS A WORLD FIRST
SICK has unveiled the world’s first photoelectric sensor with a touchscreen display, heralding the future for universal and easy-set-up sensing. The SICK W10 is a versatile all-in-one sensor that represents a major step forward in precise detection technology, adaptable for countless industrial automation applications. The sensor’s swipe-up touchscreen technology and simple icons enable
intuitive set-up and teach-in. The W10’s settings are pre-configured for rapid installation with common sensor functions, such as background or foreground suppression, available to select from a single device. With just four product variants, choosing the sensor you need for your
application has never been more straightforward, the company states. The SICK W10 is a photoelectric proximity sensor that uses intelligent onboard algorithms
developed from the experience of common industry applications to achieve high repeatability across the board. With an IP69K-rated stainless steel housing and eye-safe Class One visible red laser, it adapts effortlessly to widespread uses in factory and logistics automation with built-in modes for standard, high-speed or precision operation. The robust SICK W10 is just as resilient to harsh washdown environments as it is on fast-moving production lines. The SICK W10 therefore masters everyday presence and leading-edge detection duties, even with highly-reflective, dark or uneven surfaces. It is ideal, for example, for level detection in bowl feeders, or presence detection of components with irregular shapes or heights, even if they have shiny metal surfaces. The W10 has a secure screen locking function and access restrictions can be set up to prevent
unwanted changes to the sensor settings. It also incorporates IO-Link connectivity. The SICK W10 uses the precise laser triangulation detection principle. Accurate and reliable
operation is assured by the focused beam that produces a small light spot and a precise evaluation receiver.

shuttles, conveyors, lifts and mobile robots. The SWD125 & SWD150 can be deployed on applications such as logistic robots, mobile platforms, AGVs and AMRs with maximum speeds from 0.5 to 3m/s.
FAST DEVELOPMENT For fast development, the SWD Starter Kit is available. This is designed to facilitate and accelerate the development of AGVs and AMRs using IDEC’s exclusive SWD Safety Wheel Drive technology. Pre-assembled (out of the box) with a safety laser scanner, an on-board computer and a 24V rechargeable battery, the Starter Kit platform enables the user to start developing their mobile robot straight away.
