Abstract

Object Goal Navigation (ObjectNav) refers to an agent navigating to an object in an unseen environment, which is an ability often required in the accomplishment of complex tasks. Though it has drawn increasing attention from researchers in the Embodied AI community, there has not been a contemporary and comprehensive survey of ObjectNav. In this survey, we give an overview of this field by summarizing more than 70 recent papers. First, we give the preliminaries of the ObjectNav: the definition, the simulator, and the metrics. Then, we group the existing works into three categories: 1) end-to-end methods that directly map the observations to actions, 2) modular methods that consist of a mapping module, a policy module, and a path planning module, and 3) zero-shot methods that use zero-shot learning to do navigation. Finally, we summarize the performance of existing works and the main failure modes and discuss the challenges of ObjectNav. This survey would provide comprehensive information for researchers in this field to have a better understanding of ObjectNav. Note to Practitioners —This work was motivated by the increased interest in real-world applications of mobile robots. Object Goal Navigation (ObjectNav), which is an important task in these applications, requires an agent to find an object in an unseen environment. To accomplish that, the agent needs to be equipped with the capability to move in the environment, decide where to go, and recognize the object categories. So far, most works on ObjectNav have been done in a simulation environment. We present an overview of the existing works in ObjectNav and introduce them in three categories. Additionally, we analyze the current performance of ObjectNav and the challenges for future research. This paper provides researchers and practitioners with a comprehensive overview of the developed methods in ObjectNav, which can help them to have a good understanding of this task and develop suitable solutions for applications in the real world.
