About

Nicholas Rubies is a precision engineering researcher whose work centers on advancing nano-positioning and scanning microscopy technologies. His primary research areas include parallel kinematic design, flexure-based mechanisms, and high-precision motion control for scientific instrumentation. Rubies’s most notable contribution is the development of the Delta Robot—a novel long-travel nano-positioning stage designed for scanning x-ray microscopy. This innovative parallel kinematic architecture, which employs three orthogonal voice coils actuating parallelogram flexures, achieves a remarkable 3 mm travel range while maintaining sub-nanometer rms position jitter. The design represents a significant leap in balancing extended motion range with ultra-high precision, addressing a critical challenge in nanoscale imaging. Though early in his career, with his flagship paper accumulating 4 citations, the work has already demonstrated clear impact by offering a practical solution for next-generation x-ray microscopy systems. Rubies’s achievement lies in translating complex kinematic theory into a functional stage that pushes the boundaries of positioning accuracy, making him a promising figure in precision mechatronics and a researcher to watch in the field of advanced scientific instrumentation.
