PhD Thesis Proposal

Event Location: GHC 8115Abstract: Humanoid robots represent the state of the art in complex robot systems, but the design of controllers can be challenging and tedious. High performance controllers that can handle unknown perturbations will be required if complex robots are to one day interact safely with people in everyday environments. The high degree of [...]

Event Location: GHC 6115Abstract: Robots with legs have a number of advantages over those with wheels, such as greater ability to navigate through rough terrain, more flexible manipulation of objects, and fully holonomic control of the body. However, leveraging these advantages on a multi-legged system is computationally intensive and often relegates leg usage exclusively to [...]

Event Location: NSH 1109Abstract: Maps are important for both human and robot navigation. Given a route, driving assistance systems brief maps to guide human drivers to their destinations. Similarly, topological maps of road network provide a robotic vehicle with information about where it can drive and what driving behaviors it should use. Maps simplify both [...]

Event Location: NSH 1305Abstract: Water drops are present throughout our daily lives. Microscopic droplets create fog and mist, and large drops fall as rain. Because of their shape and refractive properties, water drops exhibit a wide variety of visual effects. If not directly illuminated by a light source, then they are difficult to see. But [...]

Event Location: Newell Simon Hall 1507Abstract: Motion planning and navigation of outdoor mobile robots has received a lot of attention in the last thirty years, yet today it still remains a challenging problem. Among the many reasons, three stand out. First, most physical mobility systems feature differential constraints that render the coupling between the control [...]

Event Location: NSH 3305Abstract: Robotic motion planning is known to be an NP Hard problem. Many real-world applications employ hierarchical planning to decompose a complex problem into a set of sub-problems, each addressed by a sub-planner that makes different trade-offs and assumptions. To achieve scalability, long-range planners such as D* simplify the robot’s motion model, [...]

Event Location: NSH 3305Abstract: This proposal is concerned with the problem of image understanding. Given a single static image, the goal is to explain the entire image by recognizing all of the objects depicted in the image. We formulate the problem of image understanding as image parsing -- breaking up the image into semantically meaningful [...]

Event Location: NSH 1507Abstract: Subterranean environments are among the most hazardous, remote and unexplored in the solar system. Subsurface applications represent the prime unexploited opportunity for robotic modeling, yet robot mappers are seldom utilized. Human survey is often preferred for reasons of economy, resulting in unnecessary risk and substandard quality. There is urgent need to [...]

Event Location: NSH 1305Abstract: Spatial and temporal alignment are fundamental problems in computer vision that arise naturally in many real-world applications ranging from object localization and visual tracking to image categorization and activity recognition. Most alignment algorithms can be posed as an optimization problem of an energy function over a set of allowable spatial or [...]
