Current research

I currently design systems typically involving autonomous vehicles (ocean robots) to pursue a number of scientific objectives. My research focuses on the interplay of marine digital communication and vehicle autonomy.


Acoustic communications on autonomous vehicles

Robust and relatively high throughput communications between vehicles is essential for multiple node collaboration (for a number of widely different tasks ranging from target tracking to geological surveying).

    Command and control of hetereogenous vehicle networks

    Commanding multiple vehicles of different types by a single operator requires a unified software infrastructure and abstraction. We have demonstrated successful field operations with a mixture of assets by combining MOOS-IvP (for autonomy and abstraction), geov (for visualization), and goby-acomms (for acoustic communications).

    Much of my graduate work continues into the present, and is thus listed above. Here are a few projects from my time as a graduate student that I am not actively pursuing:


    Adaptive oceanography

    • { Presentation: 10.31.07 acoustics seminar (MIT) – adaptive sampling background and preliminary results from PN07 }

    Cluster autonomy for target tracking

    Single vehicles, regardless of the sophistication of their sensors, are inherently limited in their ability to detect and track multiple targets. a target could be a whale or a terrorist submarine, for example.

    Thus, in these situations, a cluster of vehicles working together to localize and track targets over a region of ocean can be useful. while even a single robot can be tricky to program, a new set of challenges emerge when multiple robots must work together (think of preschoolers first interacting with other children).

    We have developed and are studying a “zone defense” (think basketball) system of target tracking that involves multiple vehicles collaborating without sharing information beyond their positions, as network bandwidth is extremely limited in the ocean environment.
