RFUniverse: A Physics-based Action-centric Interactive Environment for Everyday Household Tasks
share
Household environments are important testbeds for embodied AI research. Many simulation environments have been proposed to develop learning models for solving everyday household tasks. However, though interactions are paid attention to in most environments, the actions operating on the objects are not well supported concerning action types, object types, and interaction physics. To bridge the gap at the action level, we propose a novel physics-based action-centric environment, RFUniverse, for robot learning of everyday household tasks. RFUniverse supports interactions among 87 atomic actions and 8 basic object types in a visually and physically plausible way. To demonstrate the usability of the simulation environment, we perform learning algorithms on various types of tasks, namely fruit-picking, cloth-folding and sponge-wiping for manipulation, stair-chasing for locomotion, room-cleaning for multi-agent collaboration, milk-pouring for task and motion planning, and bimanual-lifting for behavior cloning from VR interface. Client-side Python APIs, learning codes, models, and the database will be released. Demo video for atomic actions can be found in supplementary materials: <https://sites.google.com/view/rfuniverse>
