n TECHNOLOGY May 2023 16 ABB ROBOTICS SAYS IT has transformed its AMRs (autonomous mobile robots) by adding a technology that allows them to make intelligent navigation decisions in challenging environments. Using AI-enabled 3D vision to perform location and mapping functions, the Visual Slam (simultaneous localisation and mapping) technology will speed up production, making it more flexible and efficient, while cutting commissioning times by up to 20%, reducing the need for calibration and avoiding infrastructure changes. ABB claims that Visual Slam offers significant advantages over other types of navigation, such as magnetic tape, QR codes or 2D Slam systems, that need additional infrastructures to function. ABB Robotics president Marc Segura predicts that the technology will make operations “faster, more efficient and more flexible, while freeing up employees to take on more rewarding work”. AMRs equipped with the technology can operate safely in dynamic, human-populated environments, offering more autonomy and intelligence, he adds. Visual Slam “provides a new level of intelligence for AMRs that transforms robotic applications, from production and distribution through to healthcare.” The technology uses cameras on board the AMR to create a real-time 3D map of surrounding objects. It can differentiate between fixed references – such as floors, ceilings and walls, that need to be added to the map – and moving objects such as people or vehicles. The cameras detect and track features in the environment, allowing the AMR to adapt to its surroundings and to determine the safest, most efficient route to its destination. Unlike 2D Slam, the 3D version does not need additional references such as reflectors or markers, thus cutting costs, saving space and achieving positioning to within 3mm. ABB says that by eliminating the need to change the environment, stop production or add infrastructure, the new technology can cut commissioning times by up to 20% compared to 2D Slam systems, making it quicker to add new AMRs into existing fleets. The technology is secure, because it analyses raw data only, with no visual images being saved on either the robot or on a server. ABB has developed the Visual Slam AMRs in collaboration the Swiss AI and 3D specialist Sevensense Robotics, with which it formed a partnership in 2021. The technology will be available on ABB’s T702V AMRs from Q3 2023 and its P604V AMRs from Q4 2023. These will be followed by other AMRs. SIEMENS HAS ANNOUNCED simulation software that can be used to engineer and commission variablespeed drives, based on digital twins. The Sinamics DriveSim Advanced software allows users to simulate, commission and optimise Sinamics drive systems virtually before building them in the real world. Siemens says it will increase the efficiency and productivity of drive systems and machinery. The simulation is integrated into the company’s TIA Portal automation platform. No extra software tools are needed. Using the digital twin, the logical and functional aspects of the drive can be simulated identically to the real drives, while electrical, magnetic and mechanical aspects are modelled partially. The tool allows machine-builders to cut their use of resources and to optimise energy efficiency, leading to more sustainable machine-building. DriveSim Advanced expands Siemens’ drives simulation portfolio which was launched in 2021 with Sinamics DriveSim Basic. The Advanced version is part of Siemens’ new Industrial Operations X interoperable portfolio of products and services for production engineering, execution, and optimisation. This portfolio is, in turn, part of the company’s Xcelerator digital business platform.
