Bi-Manual Joint Camera Calibration and Scene Representation
Haozhan Tang, Tianyi Zhang, Matthew Johnson-Roberson +1
Robot manipulation, especially bimanual manipulation, often requires setting up multiple cameras on multiple robot manipulators. Before robot manipulators can generate motion or ev…
GraphSeg: Segmented 3D Representations via Graph Edge Addition and Contraction
Haozhan Tang, Tianyi Zhang, Oliver Kroemer +2
Robots operating in unstructured environments often require accurate and consistent object-level representations. This typically requires segmenting individual objects from the rob…
3D Foundation Models Enable Simultaneous Geometry and Pose Estimation of Grasped Objects
Weiming Zhi, Haozhan Tang, Tianyi Zhang +1
Humans have the remarkable ability to use held objects as tools to interact with their environment. For this to occur, humans internally estimate how hand movements affect the obje…
Unifying Scene Representation and Hand-Eye Calibration with 3D Foundation Models
Weiming Zhi, Haozhan Tang, Tianyi Zhang +1
Representing the environment is a central challenge in robotics, and is essential for effective decision-making. Traditionally, before capturing images with a manipulator-mounted c…
