A Probabilistic Approach to Human-Robot Communication

Elizabeth Cha, Emily Meschke, Terrence Fong, Maja J Matarić

IROS 2019poster

Since robots are increasingly expected to work in concert with humans in dynamic, unstructured environments, they will need to express information about their state and actions. We propose a formalism for planning robot communication that employs a probabilistic representation of the robots world. T…

ModLight: Designing a modular light signaling tool for human-robot interaction

Elizabeth Cha, Tushar Trehon, Lancelot Wathieu, Christian Wagner, Anurag Shukla, Maja J Matarić

ICRA 2017poster

Recent work has shown the potential for lights to act as simple, yet expressive signaling mechanisms for use in a variety of human-robot applications. However, the wide range of robot shapes and sizes makes it difficult for researchers to quickly prototype and evaluate different light configurations…

Using nonverbal signals to request help during human-robot collaboration

Elizabeth Cha, Maja Matarić

IROS 2016poster

Non-humanoid robots are becoming increasingly utilized for collaborative tasks that rely on each collaborator's ability to effectively convey their mental state while accurately estimating and interpreting their partner's knowledge, intent, and actions. During these tasks, it may be beneficial or ev…
