PhD Thesis Proposal

Event Location: NSH 1507Abstract: Excavating regolith, or loose soil, on the Moon and Mars enables outposts, fuel depots, and sustained space exploration. In space missions mass is always at a premium because it is the main driver behind launch costs. Low mass, especially when combined with reduced gravity, results in machines with limited weight available [...]

Event Location: GHC 8102Abstract: We want our robots to work in human environments. However, human environments are cluttered and clutter creates problems for robotic manipulation. We propose to develop a framework for manipulation in highly cluttered environments. We propose to rearrange the environment using prehensile and non-prehensile actions. We present our preliminary work, a framework [...]

Event Location: NSH 3305Abstract: Semantic understanding of the environment is critical for many robotic tasks such as path planning, mapping, and object tracking. While important progress has been made, extracting a rich representation of the environment remains a challenging problem. This process includes not only recognizing individual objects but also understanding the contextual relations among [...]

Event Location: NSH 1109Abstract: Across many rescue, surveillance, and scientific applications, there exists a broad need to perform wide-area reconnaissance and terrain surveys, for which unmanned aerial vehicles (UAVs) are increasingly popular. This thesis considers the task of using one or more UAVs to locate an object of interest, provide continuous viewing, and rapidly re-acquire [...]

Event Location: GHC 8102Abstract: Task allocation involves the division of tasks among a team of robots, such that each robot is responsible for a subset of the tasks. Similarly, in role assignment, roles are typically defined to be performed by a single robot whose performance is independent of the composition of its team. Complex tasks, [...]

Event Location: GHC 6501Abstract: The modular snake robots in Howie Choset’s lab provide an intriguing platform for research: they have already been shown to excel at a variety of locomotive tasks and have incredible potential for navigating complex terrains, but much of that potential remains untapped. Unfortunately, many techniques that are commonly used in robotics [...]

Event Location: GHC 8102Abstract: Sequential prediction problems arise commonly in many areas of robotics and information processing. For instance, in robot navigation tasks, autonomous robots rely on the ability to make a sequence of actions, given a sequence of observations revealed to them over time, in order to reach the desired goal location. Similarly, complex [...]

Event Location: NSH 3002Abstract: Computer vision analysis of live cells in time-lapse microscopy images enables long-term continuous monitoring of a large number of intact cells with minimal human intervention, which has not been feasible by existing image processing methods with cellular staining images. Of critical importance in time-lapse microscopy image analysis is to understand the [...]

Event Location: NSH 3002Abstract: Miniature flapping flight systems hold great promise in matching the agility of their natural counterparts, bees, flies, and hummingbirds. Characterized by reciprocating wing motion, unsteady aerodynamics, and the ability to hover, insect-like flapping flight presents an interesting locomotion strategy capable of functioning at small size scales and is still a current [...]

Event Location: NSH 1507Abstract: obust to both external disturbances and modeling error. We describe a walking controller that functions by coordinating multiple low-dimensional optimal controllers. We break a simplified model of the dynamics into several subsystems that have limited interaction. Each of the subsystems are augmented with coordination variables and we use a Dynamic Programming [...]
