One year after unveiling a first-of-its-kind 'microwave brain' microchip capable of computing on ultrafast data and wireless signals, researchers from the Cornell Duffield College of Engineering have shown how the chip can encode information into its own language.
EPFL engineers have designed acoustic cavities that convert sound waves into thrust, propelling small robots and ultralight aerial vehicles without on-board actuators or electronics.
How microstepping works in stepper motors, the incremental torque cost of each resolution, and why finer microsteps do not improve positioning accuracy.
How closed-loop stepper motors use encoder feedback to eliminate missed steps, plus driver design, NEMA sizing, and when to choose a servo instead.
This guide covers what is inside a servo drive, how its nested servo loops behave, how EtherCAT and CANopen interfaces change the architecture, and how to size, tune, and safely commission one.
This article explains how a servo motor works, its construction, control loops, encoder and resolver feedback, AC and DC types, sizing math, and tuning fixes.
What a programmable automation controller is, how PACs are built and programmed, and how to choose between a PLC and a PAC.
This article explains how load cells work, the main types, what accuracy specs and OIML/NTEP classes mean, and best practices for sizing, wiring, and installation.
An OCXO maintains its quartz crystal at a controlled temperature for exceptional frequency stability. This guide covers OCXO design for timing engineers, including oven systems, temperature-control loops, crystal selection, specifications, variants, applications, and emerging trends.
Tolerance stack up is when dimensional tolerances accumulate, leading to more variation across a part or assembly.
