What is TongSIM-Asset?

As artificial intelligence (AI) rapidly advances, especially in multimodal large language models, research focus is shifting from single-modality text processing to the more complex domains of multimodal and embodied AI. Embodied intelligence focuses on training agents within realistic simulated environments, leveraging physical interaction and action feedback rather than conventionally labeled datasets. To foster embodied AI research, we introduce TongSIM, a high-fidelity, general-purpose platform for training and evaluating embodied agents.

TongSIM-Asset is the digital asset package of the TongSIM platform. The TongSIM-Asset package currently contains over 100 varied, multi-room indoor scenarios, and thousands of 3D interactive objects spanning more than 500 categories. By offering this open-source asset, TongSIM-Asset provides a unified and powerful tool for the development and testing of general embodied agents, enabling researchers from diverse AI fields to advance embodied intelligence research.

This dataset is intended for use in the TongSIM simulator for embodied in-home interaction tasks, such as object rearrangement, visual navigation, multi-agent embodied simulation, and various customized tasks.
