    "body_text": "Dream4ACT represents a robot's target configuration through four virtual-camera renders generated from its URDF model. Observations and actions can then share a video autoencoder and diffusion transformer even when different robots have different joint spaces. A training-free multiview recovery step converts predicted action views back into executable sequences. The authors report 88.98% average success on RoboTwin 2.0 and a 65.66 overall TriWorldBench score; both remain benchmark-specific results.",
