AI Article Synopsis
- A new setup for strain gauges was developed to reduce errors and enhance sensitivity in a six-axis force-moment sensor.
- The calibration process used a least squares method along with error reduction techniques to create an effective decoupling matrix, essential for minimizing errors.
- Experimental results showed significant improvements, with maximum calibration errors reduced to 3.91%, force-moment sensor measurement errors to 1.78%, and crosstalk readings to 4.78%.
Article Abstract
In this study, a novel strain gauge arrangement and error reduction techniques were proposed to minimize crosstalk reading and simultaneously increase sensitivity on a decoupled six-axis force-moment (F/M) sensor. The calibration process that comprises the least squares method and error reduction techniques was implemented to obtain a robust decoupling matrix. A decoupling matrix is very crucial for minimizing error and crosstalk. A novel strain gauge arrangement that comprised double parallel strain gauges in the decoupled six-axis force-moment sensor was implemented to obtain high sensitivity. The experimental results revealed that the maximum calibration error, F/M sensor measurement error, and crosstalk readings were reduced to 3.91%, 1.78%, and 4.78%, respectively.
