Abstract
CoFL-S is a low-level vision-language-action framework that predicts a language-conditioned flow field over the robot’s local visible sector and generates continuous trajectories by rolling out the predicted field. To train this low-level representation, each VLN-CE episode — originally a whole-episode instruction paired with an action sequence — is converted into frame-level local supervision with aligned sub-instructions and matched action, trajectory, and dense flow-field targets.
