Rackham: An Interactive Robot-Guide

International audienceRackham is an interactive robot-guide that has been used in several places and exhibitions. This paper presents its design and reports on results that have been obtained after its deployment in a permanent exhibition. The project is conducted so as to incrementally enhance the robot functional and decisional capabilities based on the observation of the interaction between the public and the robot. Besides robustness and efficiency in the robot navigation abilities in a dynamic environment, our focus was to develop and test a methodology to integrate human-robot interaction abilities in a systematic way. We first present the robot and some of its key design issues. Then, we discuss a number of lessons that we have drawn from its use in interaction with the public and how that will serve to refine our design choices and to enhance robot efficiency and acceptability

THE COOPERATIVE FIRM AS MONITORED CREDIT

Abstract. We develop a nancial-contracting theory of the cooperative rm where production requires three generic tasks: working, managing, and monitoring. Workers provide an intermediate input (or labor directly); managers convert the workers' input into a nal output; and directors monitor managers. We model the cooperative rm by letting the workers act also as directors. We show how bundling the labor and monitoring tasks can expand the scope for equilibrium market activity, even when doing so results in a strictly positive deadweight loss. Our theory provides new insight with respect to a substantial theoretical and empirical literature on the life cycle of worker-managed rms, and with respect to a complementary body of anecdotal evidence on the causes of worker buyouts and cooperative degeneration. Our theory is also consistent with dierences between the board compensation policies of cooperative rms, where members typically receive little more than travel and per-diem reimbursements, and of investor-owned rms, where members receive substantial pay often based in part on rm nancial performance
