Vision and Language Navigation in the Real World via Online Visual Language Mapping

no code implementations16 Oct 2023 Chengguang Xu, Hieu T. Nguyen, Christopher Amato, Lawson L. S. Wong

Directly transferring SOTA navigation policies trained in simulation to the real world is challenging due to the visual domain gap and the absence of prior knowledge about unseen environments.

Hierarchical Robot Navigation in Novel Environments using Rough 2-D Maps

no code implementations7 Jun 2021 Chengguang Xu, Christopher Amato, Lawson L. S. Wong

In this work, we propose an approach that leverages a rough 2-D map of the environment to navigate in novel environments without requiring further learning.
