摘要
Underwater contact manipulation couples visual decisions with vehicle stabilization and mechanism interaction. To our knowledge, WasserMan is the first multi-task simulation benchmark focused on visuomotor policy learning for manipulating articulated underwater mechanisms. The suite supports demonstration-based policy learning, alternative vehicle--arm platforms and bimanual manipulation. We compare ACT, diffusion policies and behavioral cloning under matched sample budgets, and evaluate adaptation of a pretrained SmolVLA baseline. Fixed-policy studies vary water appearance, lighting, contact parameters, actuator delay, arm properties and mechanism pose. RGB feedback controls and matched observation-history and expert-trajectory ablations examine observation and training choices. Expert references establish task feasibility under the same physical success tests. The experiments reveal task-dependent visual transfer and pose sensitivity, while contact, tracking and actuator measurements distinguish execution responses that completion alone hides. Complete expert candidate streams make the initial states associated with demonstration selection inspectable. Versioned code, demonstrations, checkpoints and per-episode physical evidence support reproducible comparisons within the simulation.
