RoboTransfer: Geometry-Consistent Video Diffusion for Robotic Visual Policy Transfer

Kavli Affiliate: Zheng Zhu | First 5 Authors: Liu Liu, Xiaofeng Wang, Guosheng Zhao, Keyu Li, Wenkang Qin | Summary: Imitation Learning has become a fundamental approach in robotic manipulation. However, collecting large-scale real-world robot demonstrations is prohibitively expensive. Simulators offer a cost-effective alternative, but the sim-to-real gap make it extremely challenging to scale. Therefore, […]
