Robotics and world models move toward grounded, corrective, compositional physical agents

Simple-WAM and Real2Gym support future modeling, video-grounded simulation, executable skills, and recovery as routes to more robust physical agents. RoboCoach adds active world-model-guided data selection, reporting major gains from 150 subtask demonstrations and transfer to held-out compositions; benchmark breadth, sim-to-real reliability, active perception, safety, and long-horizon composition remain open.
