TECHNOLOGY n SCHNEIDER ELECTRIC HAS ANNOUNCED a high-speed scara robot that it claims has a 40% smaller footprint, but a 40% longer z-arm stroke, than others in the same class. The Lexium Scara robot is aimed at repetitive tasks such as machine loading and unloading, pick-and-place, packaging and materials-handling. The machines are said to have one of the largest work areas in their category, while delivering high speed and accuracy. Schneider says that they will reduce electrical cabinet sizes and mounting space, thus cutting costs and reducing the need for expensive modifications to existing facilities. The 27kg robots can carry up to 6kg and offer maximum arm lengths from 500–700mm. Maximum speeds are 7,050–8,450mm/s, with repeatabilities of ±0.02mm. With integrated controls and motors, the robots simplify installation, reduce wiring, and can improve performance due to their short cable runs. They are also said to simplify integration without requiring specialised robotics knowledge. Operators can change settings easily. When combined with Schneider’s EcoStruxure Machine Expert Twin digital twin technology, the robots can be designed and tested virtually before installation, helping to cut capital and operating costs, and to avoid project scheduling issues and budget overruns. They can be integrated into unified control systems that include other robot topologies such as delta and Cartesian types. Precision motors and advanced control algorithms enable precision tracking and facilitate the coordinated operation of multiple robots. The robots can be upgraded using accessory kits. The IP65protected arms can be tailored to applications without needing to buy dedicated IP65 versions, potentially cutting costs further. https://www.se.com High-speed Scara robots are ‘40% smaller than their rivals’ Schneider says that its new scara robots combine small footprints with long reaches
