Mobility VLA: Multimodal Instruction Navigation with Long-Context VLMs and Topological Graphs

Chiang, Hao-Tien Lewis, Xu, Zhuo, Fu, Zipeng et al.

Understand

An elusive goal in navigation research is to build an intelligent agent that can understand multimodal instructions including natural language and image, and perform useful navigation.

  • To achieve this, we study a widely useful category of navigation tasks we call Multimodal Instruction Navigation with demonstration Tours (MINT), in which the environment prior is provided through a previously recorded demonstration video.
  • Recent advances in Vision Language Models (VLMs) have shown a promising path in achieving this goal as it demonstrates capabilities in perceiving and reasoning about multimodal inputs.
  • However, VLMs are typically trained to predict textual output and it is an open research question about how to best utilize them in navigation.
