Improving Zero-Shot ObjectNav with Generative Communication
Vishnu Sashank Dorbala, Vishnu Dutt Sharma, Pratap Tokekar +1
We propose a new method for improving zero-shot ObjectNav that aims to utilize potentially available environmental percepts for navigational assistance. Our approach takes into acc…
Is the House Ready For Sleeptime? Generating and Evaluating Situational Queries for Embodied Question Answering
Vishnu Sashank Dorbala, Prasoon Goyal, Robinson Piramuthu +3
We present and tackle the problem of Embodied Question Answering (EQA) with Situational Queries (S-EQA) in a household environment. Unlike prior EQA work tackling simple queries th…
Can LLMs Generate Human-Like Wayfinding Instructions? Towards Platform-Agnostic Embodied Instruction Synthesis
Vishnu Sashank Dorbala, Sanjoy Chowdhury, Dinesh Manocha
We present a novel approach to automatically synthesize "wayfinding instructions" for an embodied robot agent. In contrast to prior approaches that are heavily reliant on human-ann…
Personalized Embodied Navigation for Portable Object Finding
Vishnu Sashank Dorbala, Bhrij Patel, Amrit Singh Bedi +1
Embodied navigation methods commonly operate in static environments with stationary objects. In this work, we present approaches for tackling navigation in dynamic scenarios with n…
Can an Embodied Agent Find Your "Cat-shaped Mug"? LLM-Guided Exploration for Zero-Shot Object Navigation
Vishnu Sashank Dorbala, James F. Mullen, Dinesh Manocha
We present LGX (Language-guided Exploration), a novel algorithm for Language-Driven Zero-Shot Object Goal Navigation (L-ZSON), where an embodied agent navigates to a uniquely descr…
Can a Robot Trust You? A DRL-Based Approach to Trust-Driven Human-Guided Navigation
Vishnu Sashank Dorbala, Arjun Srinivasan, Aniket Bera
Humans are known to construct cognitive maps of their everyday surroundings using a variety of perceptual inputs. As such, when a human is asked for directions to a particular loca…
