CS Colloq: Volkan Isler

Time: 3:30 PM - 5 PMLocation: SSL 150Talk title: Sensing Limitations in Robotic Sensor Network Tasks
Speaker: Volkan Isler (Univ. of Minnesota)
Host: Prof. Gaurav SukhatmeAbstract:
Often, the individual components of a sensor network have limited sensing capabilities. For example, if a network node has a single camera, it can obtain only bearing information. Therefore, it is important to understand what effect these limitations have on fundamental robotic sensor network tasks. In this talk, I will present two recent results addressing these limitations.
First, I will present an algorithm for a sensor placement problem which arises in monitoring and surveillance tasks: We are given an environment and an error threshold. The objective is to place a minimum number of cameras so that no matter where the target is located in the environment, the uncertainty in localizing the target is less than the threshold. For this problem, I will present a placement algorithm for the case where two cameras are assigned to each candidate target location, and show that the deviation of its performance from the optimal placement is bounded by a constant factor.
Second, I will present a solution to a pursuit problem which arises in tracking applications. Can a pursuer with a bearing-only sensor capture an evader?
I will conclude the talk with an overview of our ongoing research in environmental robotics and human-robot interaction.Bio:
