" Enabling High Speed Autonomous Flights"
Autonomous mobile robots are required to operate in partially known, unstructured environments. It is imperative to guarantee safety of such systems for their successful deployment. Current state of the art for guaranteeing safety does not fully exploit the sensory and dynamic capabilities of a robot. For a non-holonomic system with non-linear dynamic constraints, ... [More]

" Learning a Context-Dependent Switching Strategy for Robust Visual Odometry"
Many applications for robotic systems require the systems to traverse diverse, unstructured environments. State estimation with Visual Odometry (VO) in these applications is challenging because there is no single algorithm that performs well across all environments and situations. The unique trade-offs inherent to each algorithm mean different algorithms excel in different environments. ... [More]

"Visual Utility to Direct Processing and Speed Up Vision Algorithms"
One of the fundamental problems in computer vision is that most computer vision algorithms are too computationally expensive to use in real-time systems. Though some speed up approaches have been found for specific algorithms (e.g. SURF vs. SIFT), there is a more general class of approaches that keep coming up in the literature and in practice. We’ll call these approaches visual utility ... [More]

"Landing the Lunar X-Prize"
Robots are transforming the future of the moon. Robot prospectors will find water, methane and metals. Robotic explorations will survey skylights, visit poles and map caves unseen from orbit. New enterprises are stretching beyond traditional government missions to deliver this future. We are embarked to privately land and rove on the moon. The agendas of the first mission are exploration, ... [More]

"On-line Mobile Robot Model Identification using Integrated Perturbative Dynamics"
We present an approach to the problem of real-time identification of vehicle motion models based on fitting, on a continuous basis, parametrized slip models to observed behavior. Our approach is unique in that we generate parametric models capturing the dynamics of systematic error (i.e. slip) and then predict trajectories for arbitrary inputs on arbitrary terrain. ... [More]

"A process for conducting (doctoral) research in robotics" [slides]
Conducting cutting edge research, especially at the doctoral level can be a confusing task. At once one must get familiar with the state of the art, identify interesting problems that have a hope of being solved and then connect them with appropriate approaches, hopefully ending with a significant contribution with compelling examples. Tall order! At first blush the process seems to defy any ... [More]

"Map-Merging-Free Connectivity Positioning for Distributed Robot Teams"
We consider a set of static towers with communication capabilities, but not within range of each other due to distance and obstacles. The goal is to achieve connectivity among the towers through a set of robots positioned in a way to act as gateways among the towers. The autonomous mobile robots are initially randomly deployed without necessarily being within range of each other, ... [More]

"Mission control of autonomous vehicles based on time logic framework" [slides]
This talk presents recent research of mission control of autonomous vehicle based on time logic framework. First an introduction to the topic of autonomous vehicles, the different control levels and the problem of mission control, is given. Then a logic control paradigm is proposed to deal with the mission control specification and solution. This approach is based on the use of linear temporal ... [More]

"Self-Aware Helicopters: A New Era for Vertical Flight"
Helicopters are useful but dangerous. A helicopter flies close to things in routine execution of its varied missions. Sometimes things go wrong and a helicopter comes into contact with an object, usually with catastrophic results. Recently our group at CMU has demonstrated technology that gives the helicopter the gift of common sense: it knows about its environment and how to act ... [More]

"Design and Development of a Multi-Hop Routing Protocol for Distributed Sensing Applications" [slides]
Wireless Sensor Networks (WSN's) is a field that has attracted the attention of many researchers these past few years. The potential applications of wireless sensor networks are immense. They are used for various applications such as habitat monitoring, agriculture, nuclear reactor control, security, etc. In this talk, I will describe the new multi-hop routing protocol that I designed for ...

"Towards a visual perception system for LNG pipe inspection" [slides]
Regular inspection for corrosion of the pipes used in Liquid Natural Gas (LNG) processing facilities is critical for safety. We argue that a visual perception system equipped on a pipe crawling robot can improve on existing non-destructive techniques (Magnetic Flux Leakage, radiography, ultrasound) by producing high resolution registered appearance maps of the internal surface. ...

"Evaluating Pose Estimation Methods for Stereo Visual Odometry on Robots" [slides]
In this talk we present a quantitative and qualitative evaluation of several pose estimation algorithms used in real-time visual odometry for mobile robots. Pose estimation plays a critical role in the stereo Structure-from-Motion visual odometry framework. Feature points are extracted at every frame and used to triangulate 3D structure. Correspondence between feature points at every frame allows ... [More]

"Improving Market-Based Task Allocation with Optimal Seed Schedules" [slides]
Task allocation impacts the performance efficiency of agent teams in significant ways. Due to their efficient and proven performance, Market-based task allocation approaches have grown in popularity for many such multi-agent domains. In addition, market-based approaches are very well suited to dynamic domains such as emergency response, in which the set of the tasks or the environment changes in ... [More]
