  • Counterfactual thinking applied to multiagent systems

    Creator:
    Zerbel, Nicholas
    Abstract:
    Multiagent approaches are well suited to designing autonomous solutions for systems that feature complex interactions between many individuals such as in autonomous traffic systems and multi-robot exploration systems. However, creating autonomous agents that function effectively in these systems is a challenging task. In these complex environments, agents need informative reward...

  • Robust Long Term Autonomy Through Local Behaviors

    Creator:
    Yates, Connor L.
    Abstract:
    Multi-robot teams offer promising solutions for many long term deployments in remote and dangerous domains, such as extraterrestrial or underseas exploration. However, long term deployments present many problems preventing robot teams from operating effectively. Learning over long time scales is makes it difficult to assign credit to robots' actions, as...

  • Toward Machine Learning-Enabled Adaptivity for Humorous Robots

    Creator:
    Gray, Carson C.
    Abstract:
    Social robots benefit from a sense of humor, which requires the ability to recognize and adapt to human responses during playful interactions. Past work on humorous robots has classified audience responses with audio-based and preliminary visual-based methods following the joke punchline. Building on this progress, we conducted a survey of...

  • Design and Initial Analysis of a Wearable Device for Anxiety Management

    Creator:
    Brown, Hannah E.
    Abstract:
    Deep pressure therapy (DPT) is a method of anxiety relief that uses pressure sensations to lower the stress response produced in the brain, and functions in a manner similar to a hug. Heavily weighted blankets and weighted vests are most commonly used to apply DPT, though recent work has shown...

  • Biomechanical Modeling of Isometric Muscle-Tendon Force Generation Through Tendons Coupled in Parallel and a Passive Differential Mechanism

    Creator:
    Le, Anthony H.
    Abstract:
    There are at least fifteen types of upper extremity tendon transfer procedures for combined peripheral nerve injuries that involve re-routing a single donor muscle to multiple recipient tendons. As a result, force and movement across finger joints become coupled, resulting in limited grasping abilities. Quantification and modeling of the donor...

  • Practical Reinforcement Learning for Bipedal Locomotion

    Creator:
    Dao, Jeremy
    Abstract:
    Reinforcement learning has emerged as a popular tool for solving control tasks, with multiple works focusing on the complex and dynamic task of locomotion. However, the naive application of reinforcement learning to this problem often produces maladaptive policies that exploit the model or reward function. This results in behavior that...

  • Deep Perception Without a Camera: Enabling 3D Reconstruction and Object Recognition using Lidar and Sonar Sensing

    Creator:
    DeBortoli, Robert A.
    Abstract:
    Deep learning has recently revolutionized robot perception in many canonical robotic applications, such as autonomous driving. However, a similar transformation has yet to occur in more harsh environments including underwater and underground. This is due in part to the difficulty in deploying robots in these environments, which lack large real...

  • Socially Communicative Multi-Robot Motion and Formation: Algorithm Development and Validation

    Creator:
    Bacula, Alexandra
    Abstract:
    Expressive motion has been found to be a highly effective tool in communicating intent and motivation in single robot human-robot interaction, but work in exploring how groups of robots can use motion in interactions with humans is relatively nascent. There are many additional complexities to consider expanding from single robot...

  • The relationships between synchrony, rapport, and small group performance

    Creator:
    Fultz, Amber A.
    Abstract:
    The purpose of this dissertation was to estimate the extent to which group-level synchrony predicts specific group outcomes. Synchrony is broadly defined as the coordination of biological and behavioral processes during social contact (Feldman, 2017). In this dissertation, biological coordination is defined as, “the spontaneous synchronization of physiological signals (e.g.,...

  • Communication Planning for Cooperative Terrain-Based Underwater Localization

    Creator:
    Anderson, Jacob
    Abstract:
    This thesis presents a decentralized communication planning algorithm for cooperative terrain-based navigation (dec-TBN) with autonomous underwater vehicles. The proposed algorithm uses forward simulation to approximate the value of communicating at each time step. The simulations are used to build a directed acyclic graph that can be searched to provide a...
