DiscoDemo-Stage2_GenData-FMB_Round-alpha0
Demonstrations for the FMB-Round task (insert a cylindrical peg into its hole on the FMB board), generated in simulation by the P-RFCL baseline generator (α = 0: the same reverse-curriculum RL without the diversity reward) of DiscoDemo. Only successful, safety-filtered episodes are kept.
