Analysis of human behavior recognition algorithms based on acceleration data
A recognition procedure based on Dynamic Time Warping and Mahalanobis distance is found to ensure good classification results and enhance the consistency of the recognition via the use of a classifier allowing unknown as an answer. Expand
Planning and obstacle avoidance in mobile robotics
A hybrid approach (Roaming Trails), which integrates a priori knowledge of the environment with local perceptions in order to carry out the assigned tasks efficiently and safely, is described, by guaranteeing that the robot can never be trapped in deadlocks even when operating within a partially unknown dynamic environment. Expand
A public domain dataset for ADL recognition using wrist-placed accelerometers
A taxonomy of ADL is proposed allowing for their categorization with respect to the most suitable monitoring approach, and a freely available dataset of acceleration data, coming from a wrist-worn wearable device, targeting the recognition of 14 different human activities is presented. Expand
Path Following for Unicycle Robots With an Arbitrary Path Curvature
A new feedback control model is provided that allows a wheeled vehicle to follow a prescribed path and guarantees asymptotic convergence to a generic 2-D curve which can be represented through its implicit equation in the form f(x,y)=0. Expand
The artificial ecosystem: a distributed approach to service robotics
A multiagent, distributed approach to autonomous mobile robotics which is an alternative to most existing systems in literature and the benefits of the approach in terms of efficiency and Real-Time responsiveness are outlined. Expand
Wearable Inertial Sensors: Applications, Challenges, and Public Test Benches
The human odometry outdoor data set (HOOD) is presented, a public data set for the PDR systems and the wearable human activity recognition folder (WHARF), a public repository forhuman activity recognition (HAR), composed of over 1,000 acceleration recordings referring to 14 daily activities, and a MATLAB library allowing the creation and validation of acceleration models of the activities. Expand
Describing and Recognizing Patterns of Events in Smart Environments With Description Logic
A system for context awareness in smart environments, based on an ontology expressed in description logic and implemented in OWL 2 EL, which is a subset of the Web Ontology Language that allows for reasoning in polynomial time. Expand
Knowledge Representation for Culturally Competent Personal Robots: Requirements, Design Principles, Implementation, and Assessment
A framework for cultural knowledge representation that relies on a three-layer ontology for storing concepts of relevance, culture-specific information and statistics, person- specific information and preferences and an algorithm for the acquisition of person-specific knowledge to drive the search is proposed. Expand
Visual feedback with multiple cameras in a UAVs Human-Swarm Interface
This article presents the implementation of a human-robot interface for the control of a swarm of UAVs, with a focus on the analysis of the effects of different visual feedbacks on the performance of human operators. Expand
Omnidirectional stereo systems for robot navigation
This paper discusses how stereo vision achieved through the use of omnidirectional sensors can help mobile robot navigation providing advantages, in terms of both versatility and performance, withExpand
