  1. Robots are ubiquitous in manufacturing settings from small-scale to large-scale. While collaborative robots (cobots) have signicant potential in these settings due to their exibility and ease of use, they can only reach their full potential when properly integrated. Specically, cobots need to be integrated in a manner that properly utilizes their strengths, improves the performance of the manufacturing process, and can be used in concert with human workers. Understanding how to properly integrate cobots into existing manufacturing workows requires careful consideration and the knowledge of roboticists, manufacturing engineers, and business administrators. In this work, we propose an approach to collaborating with manufacturers prior to the integration process that involves planning, analysis, development, and presentation of results. This approach ultimately allows manufacturers to make an informed choice about cobot integration within their facilities. We illustrate the application of this approach through a case study with a manufacturing collaborator and discuss insights learned throughout the process.

  2. Robots designed to interact with people in collaborative or social scenarios must move in ways that are consistent with the robot's task and communication goals. However, combining these goals in a naïve manner can result in mutually exclusive solutions, or infeasible or problematic states and actions. In this paper, we present Lively, a framework which supports configurable, real-time, task-based and communicative or socially-expressive motion for collaborative and social robotics across multiple levels of programmatic accessibility. Lively supports a wide range of control methods (i.e. position, orientation, and joint-space goals), and balances them with complex procedural behaviors for natural, lifelike motion that are effective in collaborative and social contexts. We discuss the design of three levels of programmatic accessibility of Lively, including a graphical user interface for visual design called LivelyStudio, the core library Lively for full access to its capabilities for developers, and an extensible architecture for greater customizability and capability.

  3. As social robots become increasingly prevalent in day-to-day environments, they will participate in conversations and appropriately manage the information shared with them. However, little is known about how robots might appropriately discern the sensitivity of information, which has major implications for human-robot trust. As a first step to address a part of this issue, we designed a privacy controller, CONFIDANT, for conversational social robots, capable of using contextual metadata (e.g., sentiment, relationships, topic) from conversations to model privacy boundaries. Afterwards, we conducted two crowdsourced user studies. The first study (n = 174) focused on whether a variety of human-human interaction scenarios were perceived as either private/sensitive or non-private/non-sensitive. The findings from our first study were used to generate association rules. Our second study (n = 95) evaluated the effectiveness and accuracy of the privacy controller in human-robot interaction scenarios by comparing a robot that used our privacy controller against a baseline robot with no privacy controls. Our results demonstrate that the robot with the privacy controller outperforms the robot without the privacy controller in privacy-awareness, trustworthiness, and social-awareness. We conclude that the integration of privacy controllers in authentic human-robot conversations can allow for more trustworthy robots. This initial privacy controller will serve as a foundation for more complex solutions.
