Reflex enables humanoid robots to catch thrown boxes using egocentric RGB-D vision
Reflex is a three-stage framework that trains a humanoid robot to catch thrown boxes by learning whole-body control, object dynamics inference, and visual grounding from egocentric RGB-D input, achieving 85.7% catch success in simulation and up to 65% on a real robot at 2.5 m.
