I. Introduction
In recent years, there has been an increase in the types of technologies adopted by law enforcement. For example, across the United States, law enforcement agencies have utilized tactical robots [1], surveillance robots [2], and aerial drones [3] to accomplish specific tasks (e.g., explosive ordinance disposal). Communication robots are also used in law enforcement since it invariably involves communication and requires the development of trust between individuals. The performance of human-robot teams is related to trust, which is directly correlated to communication modalities and successful task completion [4]. However, the development of trust between individuals can be restricted using traditional robotic platforms and technology. Current robots used by LEOs are limited due to a lack of transparency, accessibility, and usable technology. These robots may also be expensive, intimidating, and do not readily facilitate communication [4].
