Semantic Mapping for Autonomous Navigation and Exploration
Abstract: The last two decades have seen enormous progress in the sensors and algorithms for 3D perception, giving robots the means to build accurate spatial maps and localize themselves in them in real time. The geometric information in these maps is invaluable for navigation while avoiding obstacles, but insufficient, by itself, for robots to robustly [...]

Title: Mutual Information Maps for Single and Multi-Target Ergodic Search Abstract: This thesis addresses use of multi-agent systems to perform autonomous search for moving targets. Target search has many applications, including search and rescue and surveillance, but most robotic systems used in these situations require human operators. Recent works have used ergodic search methods to [...]

Title: Ultrasound-based Needle Tracking and Lateral Manipulation Planning for Common Needle Steering Abstract: Many medical interventions require inserting a needle towards the desired site. Robotic needle insertion can potentially provide reliable needle access independent of practitioner experience and availability. However, when the needle is inserted into heterogeneous tissue, the complicated needle-tissue interaction introduces multiple challenges [...]

Title: Coordinated Aerial Exploration of Subterranean Voids Abstract: Subterranean exploration has been thrust into the spotlight by the recent DARPA Subterranean Challenge. Teams are tasked with developing a multi-agent system that can rapidly navigate through unknown underground environments while sending back maps and other semantic information. A system with such capabilities has a wide [...]

Title: The design of a compact laser scanner and an integrated simulation environment for smart manufacturing Abstract: Advanced manufacturing is on the rise with the notable progress in the additive and hybrid manufacturing field. However, most of the existing solutions are open loop without sensory feedback because of the lack of a small form factor [...]

Title: Graph Neural Networks for Wind Farm Yaw Optimization Abstract: In order to mitigate the effects of climate change, it is important to maximize the power output of our wind energy resources. Wind farm control is typically greedy, with all turbines facing directly into the wind. Due to wake interactions, this leads to reductions [...]

Title: On Visual-Aided LiDAR-Inertial Odometry System in Challenging Subterranean Environments Abstract: Simultaneous Localization and Mapping (SLAM) is one of the fundamental components for autonomous robotic exploration. The goal of SLAM is to create an accurate map for the environment and provide robust state estimation for planning, control, and perception tasks. However, due to the [...]

Efficient Robot Decision-Making for Achieving Multiple Independent Tasks
Abstract: We focus on robotics applications where a robot is required to accomplish a set of tasks that are partially observable and evolve independently of each other according to their dynamics. One such domain that we target in this work is decision-making for a robot waiter waiting tables at a restaurant. The robot waiter should [...]

Title: Communication Network Flow Control With LQR and Factor Graphs Abstract: Advances in the estimation and more recently the controls communities have leveraged the use of factor graphs to overcome problems of scalability and runtime in dynamical systems. In continuation of that work, we look to use factor graphs to perform LQR control on [...]
