TITLE

Integrating human and robot decision-making dynamics


ABSTRACT

Humans and robots each have strengths and weaknesses associated with making good decisions to address complex tasks in uncertain, changing environments. We investigate how humans and robots can best jointly contribute to decision making so that strengths are exploited and weaknesses compensated. Our approach to this integration problem is to leverage experimental and modeling work of psychologists on human decision making. We seek commonality between the kinds of decisions humans make in complex tasks and the kinds of decisions humans make in psychology experiments; when commonality conditions are met, the psychology results can be used to predict how humans will behave in the complex task. A problem well studied in the psychology literature is the two-alternative forced-choice task, in which the human subject chooses between two options at regular time intervals and receives a reward after each choice. Interestingly, experiments show convergence of the aggregate behavior to rewards that are often suboptimal.
We introduce a decision-making problem associated with a complex task that integrates human and robotic decision-making dynamics with feedback. The setting is a human-supervised collective robotic foraging problem, where the human decision-making takes the form of a two-alternative forced-choice task and the reward report is a feedback from the robots. Using a popular, experimentally verified, decision-making model, we prove convergence of the human behavior to the observed aggregate decision making for reward structures with matching points. Since behavior converges to suboptimal performance, we show how adaptive laws for the robot feedback, which use only local information, can be applied to help the human make optimal decisions.

Wilsey Professor of Mechanical and Aerospace Engineering and associated faculty member of the Program in Applied and Computational Mathematics at Princeton University where she has been since 1994. In 2001 she was the Lise Meitner Guest Professor at Lund University, Sweden and in 2007 a Visiting Professor at University of Pisa, Italy. She received the B.S.E. degree in mechanical engineering from Princeton University in 1985. From 1985 to 1989, she worked as an engineer in the electric power industry. She received the M.S. and Ph.D. degrees in electrical engineering from the University of Maryland in 1991 and 1994. Her research is in nonlinear control and dynamics with current interests in cooperative control for multi-agent systems, mobile sensor networks, adaptive ocean sampling, collective behavior in fish schools and decision dynamics in mixed human/robot teams. She became an IEEE Fellow in 2007 and received the Mohammed Dahleh Award (2005), John D. and Catherine T. MacArthur Foundation Fellowship (2004), Automatica Prize Paper award (1999), ONR Young Investigator Award (1998) and NSF CAREER Award (1995).

TITLE

Architectures, abstractions, and algorithms for large teams of robots


ABSTRACT

Networked robots represent the convergence of robotics, sensor networks and mobile ad-hoc networks, with many applications and a growing market projected to be $200B in 2013. This talk will focus on some fundamental problems and practical issues underlying the deployment of large numbers of autonomously functioning robots. The central problem is the so-called inverse problem of deriving individual robot behaviors for a desired group behavior. There are numerous examples of group behavior in biology which suggest that analysis of swarming behaviors in biology may provide insight for the synthesis of collective behaviors for engineered systems. I will present a methodology for modeling and analyzing such collective behaviors and discuss architectures, abstractions and algorithms for the control of large networks of robots.
