SPARK is an innovative robotic manipulator, composed of a series of elements interconnected by rotary joints arranged with their axes of rotation parallel, thus producing planar motion of the manipulator end point. Thanks to an innovative, patented control system architecture and redundant degrees of freedom, it is characterised by excellent dynamic response, providing high accelerations, low inertia and precise control of tool speed along complex paths.
Following the successful Phase 1 submission to Horizon 2020, a feasibility study has been conducted, specifically for the exploitation of the technology as the basis for a fibre laser cutting machine. SPARK is ideally suited to this application as the finished quality of the cut surface is highly dependent on tool speed, something which heavy conventional gantry machines cannot guarantee.
