Nonlinear VNA (NVNA) development has continued for more than 20 years, and many of the early researchers have remained involved. The result of various alliances and technical approaches is a group of ...

A universal test bed for motors uses a surface acoustic-wave (SAW) sensor for gauging torque. The Nonlinear Test Bed for Actuators (NBTA), developed by Robotics Research Group and the University of ...
