Teaching robots social autonomy from in situ human supervision

Senft, Emmanuel January 2018 (has links)
Traditionally the behaviour of social robots has been programmed. However, increasingly there has been a focus on letting robots learn their behaviour to some extent from example or through trial and error. This on the one hand excludes the need for programming, but also allows the robot to adapt to circumstances not foreseen at the time of programming. One such occasion is when the user wants to tailor or fully specify the robot's behaviour. The engineer often has limited knowledge of what the user wants or what the deployment circumstances specifically require. Instead, the user does know what is expected from the robot and consequently, the social robot should be equipped with a mechanism to learn from its user. This work explores how a social robot can learn to interact meaningfully with people in an efficient and safe way by learning from supervision by a human teacher in control of the robot's behaviour. To this end we propose a new machine learning framework called Supervised Progressively Autonomous Robot Competencies (SPARC). SPARC enables non-technical users to control and teach a robot, and we evaluate its effectiveness in Human-Robot Interaction (HRI). The core idea is that the user initially remotely operates the robot, while an algorithm associates actions to states and gradually learns. Over time, the robot takes over the control from the user while still giving the user oversight of the robot's behaviour by ensuring that every action executed by the robot has been actively or passively approved by the user. This is particularly important in HRI, as interacting with people, and especially vulnerable users, is a complex and multidimensional problem, and any errors by the robot may have negative consequences for the people involved in the interaction. Through the development and evaluation of SPARC, this work contributes to both HRI and Interactive Machine Learning, especially on how autonomous agents, such as social robots, can learn from people and how this specific teacher-robot interaction impacts the learning process. We showed that a supervised robot learning from their user can reduce the workload of this person, and that providing the user with the opportunity to control the robot's behaviour substantially improves the teaching process. Finally, this work also demonstrated that a robot supervised by a user could learn rich social behaviours in the real world, in a large multidimensional and multimodal sensitive environment, as a robot learned quickly (25 interactions of 4 sessions during in average 1.9 minutes) to tutor children in an educational game, achieving similar behaviours and educational outcomes compared to a robot fully controlled by the user, both providing 10 to 30% improvement in game metrics compared to a passive robot.

Autonomy and the Future

Salvatori, Paul 29 September 2011 (has links)
This thesis introduces the idea of progressive autonomy, namely future-oriented self-governance, based on the pursuit of desired goals that one has established for oneself. As the thesis shows, focus on this sort of activity, as well as its value and importance, has been largely left out of the existing literature on autonomy. In contrast, this activity is central to progressive autonomy, which, as this thesis puts forth, enables the individual to actively determine the course of his life. Throughout the process, the individual is author of his own narrative, which, as the ongoing fulfillment of desired goals, he experiences as both meaningful and worthwhile. The thesis does not frame the narrative of the progressively autonomous individual as merely a story or an account of events. Rather, it does so as a sequence events the progressively autonomous individual is directly responsible for bringing about, as well as concretely situated in. He is, in other words, part and parcel of his narrative, as opposed to, say, a novelist who physically stands apart from the events he imagines and writes. Finally, the thesis demonstrates that, though the progressively autonomous individual is motivated by his own desires, he is more than just a pleasure seeker; he is strategically morally responsible. Such responsibility involves and is characterized by rejecting certain motives that undermine the actual achievement of desired goals, while affirming other motives that facilitate this achievement. This, as the thesis shows, renders the progressively autonomous individual more responsible than one who partakes in this rejection or affirmation, without regard to how either will impact one’s future.
