- arXiv Robotics — research abstractsquARtet Marker: A 3D-Printable Multi-Tag Fiducial for Robust Near-Frontal Pose Estimation
This research proposes quARtet Marker, a 3D-printable fiducial that uses multiple tilted tags to improve pose estimation for robotic manipulation. The design addresses the limitations of single planar tags in near-frontal views by using tilted tags that maintain perspective cues. Experiments show that the marker reduces mean frontal orientation error and root-mean-square position error significantly, with layouts featuring flat contact strips performing better in graspability tests.
