Stereo bearings-only tracking of a wheelchair from a robot
Paladyn - Tập 2 - Trang 202-210 - 2012
S. Di Benedetto, B. Marhic, L. Delahoche
This project deals with technical assistance for people of reduced mobility. The goal of this work is to have a mobile platform with an embedded prehensive arm (MANUS®) track a wheelchair. The use of this mobile unit in relation to the patient’s wheelchair is carried out on a master-slave basis. This study, therefore, has a plural-disciplinary nature: Science for the Engineer, Human, Social and Cl...... hiện toàn bộ
Towards an Articulation-Based Developmental Robotics Approach for Word Processing in Face-to-Face Communication
Paladyn - Tập 2 Số 2 - 2011
Bernd J. Kröger, Peter Birkholz, Christiane Neuschaefer‐Rube
AbstractWhile we are capable of modeling the shape, e.g. face, arms, etc. of humanoid robots in a nearly natural or human-like way, it is much more difficult to generate human-like facial or body movements and human-like behavior like e.g. speaking and co-speech gesturing. In this paper it will be argued for a developmental robotics approach for learning to speak. ...... hiện toàn bộ
Hill-climbing for a noisy potential field using information entropy
Paladyn - Tập 2 - Trang 94-99 - 2011
Piljae Kim, Satoru Nakamura, Daisuke Kurabayashi
For a robot navigation system used in an unpredictable environment, it is generally effective to create a pathway that robots can track for carrying out a given task, such as reaching a goal. In the biological world, ants construct a foraging path using a volatile substance called a pheromone, which has been widely studied and whose characteristics have been used in a transportation network model....... hiện toàn bộ
A Predictive Network Architecture for a Robust and Smooth Robot Docking Behavior
Paladyn - - 2012
Junpei Zhong, Cornelius Weber, Stefan Wermter
AbstractRobots and living beings exhibit latencies in their sensorimotor processing due to mechanical and electronic or neural processing delays. A reaction typically occurs to input stimuli of the past. This is critical not only when the environment changes (e.g. moving objects) but also when the agent itself moves. An agent that does not predict while moving may ...... hiện toàn bộ
Cognitive map plasticity and imitation strategies to improve individual and social behaviors of autonomous agents
Paladyn - Tập 1 - Trang 25-36 - 2010
Philippe Laroque, Nathalie Gaussier, Nicolas Cuperlier, Mathias Quoy, Philippe Gaussier
Starting from neurobiological hypotheses on the existence of place cells (PC) in the brain, the aim of this article is to show how little assumptions at both individual and social levels can lead to the emergence of non-trivial global behaviors in a multi-agent system (MAS). In particular, we show that adding a simple, hebbian learning mechanism on a cognitive map allows autonomous, situated agent...... hiện toàn bộ
Theo dõi và phân đoạn sử dụng min-cut với hình dạng tiên quyết liên tiếp Dịch bởi AI
Paladyn - Tập 1 - Trang 73-79 - 2010
Junqiu Wang, Yasushi Yagi
Theo dõi và phân đoạn có một loạt ứng dụng rộng rãi như cảm biến thông minh của robot, tương tác người-máy và giám sát video. Tuy nhiên, theo dõi và phân đoạn gặp nhiều thách thức vì nhiều lý do, chẳng hạn như hình dạng đối tượng phức tạp và nền lộn xộn. Chúng tôi đề xuất một thuật toán theo dõi và phân đoạn sử dụng các hình dạng tiên quyết theo cách liên tiếp. Chúng tôi phát hiện ra rằng thông ti...... hiện toàn bộ

A robotic framework for controlling human’s attention
Paladyn - Tập 3 - Trang 92-101 - 2012
Mohammed Moshiul Hoque
It is a major challenge in HRI to design a social robot that is able to selectively direct a target human’s attention towards an intended direction. For this purpose, the robot may first turn its gaze toward him/her in order to establish eye contact. However, such a turning action of the robot may not in itself be sufficient to make eye contact with the target person in all situations, especially ...... hiện toàn bộ
An anthropomimetic approach to high performance traction control
Paladyn - - 2011
William Kirchner, Steve C. Southward
The ability to learn and adapt to changing environmental conditions, as well as develop perceptive models based on stimulus-response data, provides expert human drivers with significant advantages. When it comes to bandwidth, accuracy, and repeatability, automatic control systems have clear advantages over humans; however, most high performance control systems lack many of the unique abilities of ...... hiện toàn bộ
Toward autonomous, compliant, omnidirectional humanoid robots for natural interaction in real-life settings
Paladyn - Tập 1 - Trang 57-65 - 2010
François Michaud, François Ferland, Dominic Létourneau, Marc-Antoine Legault, Michel Lauria
The field of robotics has made steady progress in the pursuit of bringing autonomous machines into real-life settings. Over the last 3 years, we have seen omnidirectional humanoid platforms that now bring compliance, robustness and adaptiveness to handle the unconstrained situations of the real world. However, today’s contributions mostly address only a portion of the physical, cognitive or evalua...... hiện toàn bộ
Motion planning of a snake-like robot using an optimized harmonic potential field
Paladyn - Tập 1 - Trang 187-197 - 2011
Samer Charifa, Marwan Bikdash
Snake-like robots have gained popularity in the last three decades for their ability to utilize several gaits in order to navigate through different terrains. They are analogous in morphology to snakes, tentacles, and elephant trunks. We propose a novel method of navigating a snake-like robot based on the Harmonic Field with Optimized Boundary Conditions (HFOBC) and a boundary following algorithm....... hiện toàn bộ
