The use of coreference resolution for understanding manipulation commands for the PR2 Robot
… with robots such as the Personal Robot 2 (PR2), without the need for a special training or equipment. Programming such a robot to follow commands is challenging because natural language has a complex structure and semantics, a model for which needs to be based on linguistic knowledge or …

The receptor tyrosine phosphatase Ptp69D and the receptor tyrosine kinase Pvr in Drosophila nervous system development
… Interestingly, the cytoplasmic tyrosine kinase PR2 binds Ptp69D, and the C. elegans homolog of PR2 has been found to suppress the Egfr/Ras pathway. Other evidence suggests that the Egfr/Ras pathway may be required for axon outgrowth. In addition to PR2, I also identified the receptor tyrosine …

Following recipes with a cooking robot
In this thesis, we present BakeBot, a PR2 robot system that interprets natural language baking recipes into baking instructions which it follows to execute the recipe, from mise en place presentation of the ingredients through baking in a toaster oven. We developed parameterized motion primitives …

State estimation for manipulation with compliance control and force sensing
… force and impedance controller is developed on a PR2 robot. Higher-dimensional generalizations, planning, and empirical results are the subject of future work.

Interaction Of Severity Of Stressor And Coping Strategy On Psychological Distress From A Psychological Flexibility Conceptualization
… stressor (β = -15.08, t(443) = -7.06, p <.001, pr2 = .121). There were two significant interactions. The effect of severity of stressor on overall psychological distress is conditional on our measure of mindfulness and engagement as a coping strategy (β = -.02, t(442) = -2.18, p = .030, pr2 = …

Motion Planning for Manipulation With Heuristic Search
… motion planning with upright constraints on a PR2 robot operating in non-trivial cluttered spaces. Then I will explain how we extended our approach to manipulation planning for n-arms with regrasping. In this work, the planner itself makes all of the discrete decisions, including which arm to …

Learning a strategy for whole-arm grasping
… on the problem of whole-arm grasping for a PR2, where one or both arms, as well as the torso can all serve to create contacts.

How Can Robots Adapt To A Social Human World? A Study Into The Role Gestures Can Play In Human-Robot Relations
… human-robot interactions. Conducted using the PR2, this study explored the role of gestures in two basic kinds of communications: the robot communicating a need: low power) to an unsuspecting human, and a robot building trust with a human participant on an instruction reading task. We predicted …

Active Vision for Object Recognition by Dynamically Fusing Eye-in-Hand Data
… camera allocation, and we implement it on a PR2 robotic platform. It involves a head-mounted 3D camera (capturing RGB and depth information) working in cooperation with a hand-mounted camera (capturing RGB information only). The hand camera is dynamically employed to assist in recognizing …

Computation of Suitable Grasp Pose for Usage of Objects Based on Predefined Training and Real-time Pose Estimation
… We conducted experiments using a humanoid PR2 robot. We used the Robot Operating System as the primary framework of the system and MoveIt Interface for manipulation of grasps. The grasping system showed robust results for different poses of the objects using both arms of the robot. Our …

Characterisation of the AT4G11100 gene, a negative regulator of disease resistance in Arabidopsis thaliana
… induction of the salicylic acid defence gene PR2 following Pst infection, suggesting that AT4G11100 may too be a negative regulator of immunity. Additionally, a plant line with exceptionally high AT4G11100 expression levels displayed distinct leaf morphology, possibly implicating AT4G11100 in …

Minimalist Hardware Architectures for Agent Tracking and Guidance
… of their versatility, complex robots such as the PR2 (which cost hundreds of thousands of dollars) are impractical for many common applications. Instead, if a specific task is required, sensing and computational requirements can be determined specific to that task, and a clever hardware …
