ModBot is a simple robotics platform created for testing sensors, algorithms, vision systems, and everything else in between. I designed this platform with modularity in mind (thus the name) which requires the compartmentalization of behaviors and functions into discrete and, ideally, interchangeable modules. Since this is an experimental platform I opted not tie it to ROS (even though it still uses a Linux environment so ROS can be used) and created a very simple ASCII protocol for communication between modules. Lastly, I added teleoperation capabilities using a PlayStation DualShock 4 controller.Continue reading ModBot: A Modular Robotics Test Platform

The recent years have witnessed an increase in natural disasters in which the destruction of essential communication infrastructure has significantly affected the number of casualties. In 2005, Hurricane Katrina in the United States resulted in over 1,900 deaths, three million land-line phones disconnections, and more than 2000 cell sites going out of service. This incident highlighted an urgent need for a quick-deployment, efficient communication network for emergency relief purposes. In this research, a fully autonomous system to deploy Unmanned Aerial Vehicles (UAVs) as the first phase disaster recovery communication network for wide-area relief is presented. As part of this system, an automation algorithm has been developed to control the deployment and positioning of the UAVs based on a traditional cell network structure utilizing 7-cell clusters in a hexagonal pattern. In addition to the software algorithm, a fully functional control interface was developed which allowed for full control of the system both locally and over an internet connection. This system represents a novel approach for handling a large-scale autonomous deployment of a UAV communications networks.
