In this paper, we present a Covariance Intersection (CI)-based algorithm for reducing the processing and communication complexity of multi-robot Cooperative Localization (CL). Specifically, for a team of N robots, our proposed approximate CI-based CL approach has processing and communication complexity only linear, O(N), in the number of robots. Moreover,(More)
OBJECTIVE Translation, cultural adaptation and validation of the Brazilian Portuguese version of the Edinburgh Claudication Questionnaire (ECQ) a specific tool to assess intermittent claudication. METHODS The Brazilian Portuguese version of the ECQ was developed after authorization by the University of Edinburgh. It was applied to 217 individuals: São(More)
Using internal and external sensors to provide position estimates in a two-dimensional space is necessary to solve the localization and navigation problems for a robot or an autonomous vehicle (AV). Usually, a unique source of position information is not enough, so researchers try to fuse data from different sensors using several methods, as, for example,(More)
BACKGROUND There is controversy in the literature regarding the strategy used to obtain better outcomes after performing an anterior temporal lobectomy (ATL). Some investigators prefer to reduce the risks and costs of the predictor studies despite the fact that the number of patients cured after ATL (no seizures with no medication) is relatively small.(More)
This article deals with accurate position estimation and propagation in autonomous vehicles. This article is centered on how we can accurately estimate the robot pose uncertainty and how this uncertainty is propagated to future states (the robot state, in this context, is its pose). Some attention has been paid to this issue in the past. The first approach(More)
In this paper, we consider the problem of autonomous exploration of unknown environments with single and multiple robots. This is a challenging task, with several potential applications. We propose a simple yet effective approach that combines a behavior-based navigation with an efficient data structure to store previously visited regions. This allows(More)
Developing an infrastructure for efficiently coordinating a group of autonomous robots has become a challenging need in robotics community. In recent years, the use of teams of coordinated mobile robots has been explored in several application fields such as military, exploration, surveillance, and search and rescue missions. For such fields, the use of(More)
