Abstract
We developed an accurate kinematic model of our six-axis serial robotic arm used for antenna characterization measurements. The model was calibrated over a 0.4 m3 working cell. We validated the calibration using a 1 m2 plane embedded within the calibration cell. The positioning errors for the calibrated case showed a fourfold improvement in accuracy as compared to the uncalibrated case. For a maximum positioning error tolerance of λ/50, the calibrated model should allow for open-loop antenna characterization measurements out to 35 GHz.
