Currently, assistive robots and prosthesis have a difficult time giving and receiving objects to and from humans. While many attempts have been made to program handover scenarios into robotic control algorithms, the algorithms are typically lacking in at least one important feature: intuitiveness, safety, and efficiency. By performing a study to better understand human-to-human handovers, we observe trends that could inspire controllers for object handovers with robots. Ten pairs of human subjects handed over a cellular phone-shaped, instrumented object using a key pinch while 3D force and motion tracking data were recorded. It was observed that during handovers, humans apply a compressive force on the object and employ linear grip force to load force ratios when two agents are grasping an object (referred to as the "mutual grasp period"). Results also suggested that object velocity during the mutual grasp period is driven by the receiver, while the duration of the mutual grasp period is driven by the preference of the slowest agent involved in the handover. Ultimately, these findings will inspire the development of robotic handover controllers to advance seamless physical interactions between humans and robots.

The majority of trust research has focused on the benefits trust can have for individual actors, institutions, and organizations. This “optimistic bias” is particularly evident in work focused on institutional trust, where concepts such as procedural justice, shared values, and moral responsibility have gained prominence. But trust in institutions may not be exclusively good. We reveal implications for the “dark side” of institutional trust by reviewing relevant theories and empirical research that can contribute to a more holistic understanding. We frame our discussion by suggesting there may be a “Goldilocks principle” of institutional trust, where trust that is too low (typically the focus) or too high (not usually considered by trust researchers) may be problematic. The chapter focuses on the issue of too-high trust and processes through which such too-high trust might emerge. Specifically, excessive trust might result from external, internal, and intersecting external-internal processes. External processes refer to the actions institutions take that affect public trust, while internal processes refer to intrapersonal factors affecting a trustor’s level of trust. We describe how the beneficial psychological and behavioral outcomes of trust can be mitigated or circumvented through these processes and highlight the implications of a “darkest” side of trust when they intersect. We draw upon research on organizations and legal, governmental, and political systems to demonstrate the dark side of trust in different contexts. The conclusion outlines directions for future research and encourages researchers to consider the ethical nuances of studying how to increase institutional trust.

In order for a robot to solve complex tasks in real world, it needs to compute discrete, high-level strategies that can be translated into continuous movement trajectories. These problems become increasingly difficult with increasing numbers of objects and domain constraints, as well as with the increasing degrees of freedom of robotic manipulator arms.

The first part of this thesis develops and investigates new methods for addressing these problems through hierarchical task and motion planning for manipulation with a focus on autonomous construction of free-standing structures using precision-cut planks. These planks can be arranged in various orientations to design complex structures; reliably and autonomously building such structures from scratch is computationally intractable due to the long planning horizon and the infinite branching factor of possible grasps and placements that the robot could make.

An abstract representation is developed for this class of problems and show how pose generators can be used to autonomously compute feasible robot motion plans for constructing a given structure. The approach was evaluated through simulation and on a real ABB YuMi robot. Results show that hierarchical algorithms for planning can effectively overcome the computational barriers to solving such problems.

The second part of this thesis proposes a deep learning-based algorithm to identify critical regions for motion planning. Further investigation is done whether these learned critical regions can be translated to learn high-level landmark actions for automated planning.

This Creative Thesis is a popularization on the subject of Dark Patterns. Dark Patterns are deceptive functionality implemented online by developers seeking to manipulate users and benefit from their misfortune. They work by using psychological techniques to influence a user’s behavior, like by toying with a user’s emotion. I hope to spread the knowledge of Dark Patterns to as many people as possible. Once people know how Dark Patterns work, Dark Patterns will not be effective on them anymore.
