Examining Audio Communication Mechanisms for Supervising Fleets of Agricultural Robots
Abhi Kamboj, Tianchen Ji, Katie Driggs-Campbell

TL;DR
This study investigates audio communication methods for supervising agricultural robot fleets, finding that single-phrase audio cues are preferred and potentially improve operator efficiency during failure diagnosis.
Contribution
It introduces a simulation platform and evaluates three audio communication methods, highlighting the effectiveness of single-phrase cues for remote robot supervision.
Findings
Single-phrase audio communication is most preferred by users.
Single phrases may enable more efficient secondary task completion.
Participants favored simpler, concise audio cues for robot failure reporting.
Abstract
Agriculture is facing a labor crisis, leading to increased interest in fleets of small, under-canopy robots (agbots) that can perform precise, targeted actions (e.g., crop scouting, weeding, fertilization), while being supervised by human operators remotely. However, farmers are not necessarily experts in robotics technology and will not adopt technologies that add to their workload or do not provide an immediate payoff. In this work, we explore methods for communication between a remote human operator and multiple agbots and examine the impact of audio communication on the operator's preferences and productivity. We develop a simulation platform where agbots are deployed across a field, randomly encounter failures, and call for help from the operator. As the agbots report errors, various audio communication mechanisms are tested to convey which robot failed and what type of failure…
