DOI: 10.1017/s0263574721002034
Abstract: A classic hand-eye system involves hand-eye calibration and robot-world and hand-eye calibration. Insofar as hand-eye calibration can solve only hand-eye transformation, this study aims to determine the robot-world and hand-eye transformations simultaneously based on the… read more here.

DOI: 10.1109/lra.2022.3146943
Abstract: An analysis of the existing hand-eye calibration methods reveals that most of them are far from trivial. And, what is worse, their intrinsic complexity makes it difficult to elucidate under which circumstances they fail to… read more here.

DOI: 10.1109/lra.2022.3194690
Abstract: Soft continuum arms (SCAs) that are controlled by visual servoing (VS) present trade-offs between the camera range and tracking accuracy. Cameras placed at a distance (eye-to-hand) can observe a larger workspace area and the SCA… read more here.

DOI: 10.1109/taes.2020.2982482
Abstract: The hand–eye measurements have recently been proven to be very efficient for spacecraft attitude determination relative to an ellipsoidal asteroid. However, the recent method does not guarantee full attitude observability for all conditions. This article… read more here.
