— In this paper, we describe a remote lab system that allows remote groups to access a shared PR2. This lab will enable a larger and more diverse group of researchers to participate directly in state-of-the-art robotics research and will improve the reproducibility and comparability of robotics experiments. We identify a set of requirements that apply to(More)
Development of a rhythmic sense comes early in childhood development , and appears crucial for learning speech as well as music. Synchronized , rhythmic movements governed by oscillators play significant roles in industrial robots, but only in tightly controlled, precisely defined environments. Prior research focuses on the synchronization of the robot's(More)
This paper documents the technology developed during the creation of the PR2 Remote Lab and the process of using it for shared development for Learning from Demonstration. Remote labs enable a larger and more diverse group of researchers to participate directly in state-of-the-art robotics research and will improve the reproducibil-ity and comparability of(More)
Sensor networks are an exCltmg new kmd of computer system. Consisting of a large number of tiny, cheap computational de­ vices physically distributed in an environ­ ment, they gather and process data about the environment in real time. One of the central questions in sensor networks is what to do with the data, i.e. how to reason with it and how to(More)
— Music performance is an important, well-structured setting for evaluating a robot's ability to detect, understand and respond appropriately to complex human activity. Social tasks such as cooperative performance require participants to detect, interpret and attune to the actions of their partners quickly and accurately. The synthesis of multiple sensory(More)
The functional significance of alternate forms of plasticity in the brain (such as apoptosis and neurogenesis) is not easily observable with biological methods. Employing Hebbian dynamics for synaptic weight development, a three-layer neural network model of the hippocampus is used to simulate nonsupervised (autonomous) learning in the context of apoptosis(More)
— We describe our efforts to create infrastructure to enable web interfaces for robotics. Such interfaces will enable researchers and users to remotely access robots through the internet as well as expand the types of robotic applications available to users with web-enabled devices. This paper centers on rosjs, a lightweight Javascript binding for ROS,(More)
We present a study of using a robotic learning from demonstration system capable of collecting large amounts of human-robot interaction data through a web-based interface. We examine the effect of different perceptual mappings between the human teacher and robot on the learning from demonstration. We show that humans are significantly more effective at(More)
We present rosbridge, a middleware abstraction layer which provides robotics technology with a standard, minimalist applications development framework accessible to applications programmers who are not themselves roboticists. Rosbridge provides a simple, socket-based programmatic access to robot interfaces and algorithms provided (for now) by ROS, the(More)
