Dynamic effects in high-performance visual servoing

Abstract

The authors discuss three dominant dynamic effects that are manifested in the use of robot end-mounted cameras for high-performance tracking and positioning tasks. They are time delay (or latency in the sensing and control blocks), time-varying loop gain due to perspective, and vibrations due to structural and drive compliance. Analysis of the dynamic is presented and compared with experimental results.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
