Detection of Residual Vibration in Robot Arms

・Issues

As robot arms become faster and more accurate, minute residual vibrations that occur after a stop can affect positioning accuracy and cycle time. These vibrations are extremely small, and conventional methods often lack the resolution needed to detect minute changes accurately.

・Solutions

A tilt sensor detects minute angular changes caused by weak vibration and quantifies them. Because the measurement resolution is independent of the working distance, stable measurement is possible even when the distance to the target changes. These features visualize residual vibration that is difficult to detect using conventional methods and enable high-precision analysis of vibration characteristics.
