Many generated sequences lack metric geometry, grasp grounding, kinematic feasibility, and execution-time feedback, so direct trajectory replay is unreliable in real settings. GenVid2Robot introduces a rigid-geometric consistency framework that validates generated 2D motion using sparse relative SE(3) grounding from an initial RGB-D frame, transfers only geometrically consistent motion to the robot, and applies grasp-conditioned execution.

A generated video usually lacks metric geometry, grasp grounding, robot kinematic feasibility, and execution-time feedback, which makes direct trajectory replay unreliable in real-world manipulation. This paper presents GenVid2Robot, a rigid-geometric consistency framework that converts generated video motion into executable real-robot manipulation trajectories. Given an initial RGB-D observation anda task instruction, GenVid2Robot samples task-relevant semantic anchors from the real first frame, tracks these anchors through generated video candidates, and verifies whether the resulting 2D motion can be explained by first-frame RGB-D anchors under a sparse relative SE(3) model. In this way, generated videos are treated as uncertain visual motion hypotheses rather than direct robot demonstrations. Only geometrically consistent motion is transferred to the robot. The accepted relative motion is then applied to the real grasp-time TCP pose selected by maskconstrained grasping, producing a grasp-conditioned execution trajectory that is consistent with both the visual motion prior and the physical grasp configuration. To reduce execution mismatch caused by RGB-D noise, calibration residuals, and small contact-induced displacement, a bounded depth-compensation module corrects local depth-direction errors without assuming full online replanning. Real-robot experiments demonstrate that GenVid2Robot improves the reliability of generated-video-guided manipulation by grounding visual motion priors with sparse metric geometry, grasp constraints, robot feasibility checking, and bounded execution feedback.  \nIndex Terms—Robot manipulation, video generation, visual motion priors, rigid-geometric consistency, sparse 6D motion recovery, grasp-conditioned trajectory induction, depth-corrected execution.  \nI. INTRODUCTION  \nRobots are increasingly expected to perform manipulation tasks from visual observations and high-level language instructions, rather than relying on manually designed trajectories for every object, scene, and task variation. Tasks such as pouring water, lifting a lid, delivering a tool, or sweeping an object require the robot to infer task-relevant object motion, establish a feasible grasp, and execute a physically valid trajectory under sensing and calibration uncertainty.
