Opis:: This paper presents a navigation system structure for mobile service robots in the agent-based distributed architecture. The proposed navigation system is a part of the RAPP framework. The RAPP framework is an open-source software platform to support the creation and delivery of robotic applications, which are expected to increase the versatility and utility of robots. All key navigation tasks are defined and divided into separate components. The proper allocation of navigation components, in the fouragent structure of the RAPP infrastructure, enables highdemanding computations offloading and was the main goal of this work. Navigation system components were implemented using ROS framework. Experimental results for the NAO robot executing risks detection task proved the validity of the proposed approach.

Opis:: The navigation system of a robot requires sensors to perceive its environment to get a representation. Based on this perception and the state of the robot, it needs to take an action to make a desired behavior in the environment. The actions are defined by a system that processes the obtained information. This system can be based on decision rules defined by an expert or obtained by a training or optimization process. Fuzzy logic controllers are based on fuzzy logic on which degrees of truth are used on sy‐ stem variables and has a rule‐base that stores the knowledge about the operation of the system. In this paper a fuzzy logic controller is made with the Python fuzzylab library which is based on the Octave Fuzzy Logic Toolkit, and with the Robot Operating System (ROS) for autonomous navigation of the TurtleBot3 robot on a simulated and a real environment using a LIDAR sensor to get the distance of the objects around the robot.

Tematy:: robot navigation

Opis:: This paper presents a vision-based navigation system for mobile robots. It enables the robot to build a map of its environment, localize efficiently itself without use of any artificial markers or other modifications, and navigate without colliding with obstacles. The Simultaneous Localization And Mapping (SLAM) procedure builds a global representation of the environment based on several size limited local maps built using the approach introduced by Davison [1]. Two methods for global map are presented; the first method consists in transforming each local map into a global frame before to start building a new local map. While in the second method, the global map consists only in a set of robot positions where new local maps are started (i.e. the base references of the local maps). In both methods, the base frame for the global map is the robot position at instant . Based on the estimated map and its global position, the robot can find a path and navigate without colliding with obstacles to reach a goal defined the user. The moving objects in the scene are detected and their motion is estimated using a combination of Gaussian Mixture Model (GMM) background subtraction approach and a Maximum a Posteriori Probability Markov Random Field (MAP-MRF) framework [2]. Experimental results in real scenes are presented to illustrate the effectiveness of the proposed method.

Opis:: The growing realization of the benefits to individual students and to state economies, of providing science learners with opportunities to expand their knowledge, skills and experience of knowledge-based technological design has led to seeking instructional strategies to facilitate the transition from traditional school settings to project based learning environments. This paper refers to engaging high school physics and computer-science majors in challenging design projects which seek to activate and implement the often inert formal content knowledge within the context of designing and constructing systems dealing with real world engineering challenges in robotics and electro-optics. In this paper we suggest that visualization of the problem space and guided exploration of its spatial relationships can promote the elicitation of relevant formal knowledge and lead to creative solution design. These methods are described in the context of designing and programming robot navigation and in the context of developing remote distance sensors.

Opis:: Three-dimensional scene reconstruction is an important tool in many applications varying from computer graphics to mobile robot navigation. In this paper, we focus on the robotics application, where the goal is to estimate the 3D rigid motion of a mobile robot and to reconstruct a dense three-dimensional scene representation. The reconstruction problem can be subdivided into a number of subproblems. First, the egomotion has to be estimated. For this, the camera (or robot) motion parameters are iteratively estimated by reconstruction of the epipolar geometry. Secondly, a dense depth map is calculated by fusing sparse depth information from point features and dense motion information from the optical flow in a variational framework. This depth map corresponds to a point cloud in 3D space, which can then be converted into a model to extract information for the robot navigation algorithm. Here, we present an integrated approach for the structure and egomotion estimation problem.

Opis:: Glify optyczne są nieskomplikowanymi znakami graficznymi zawierającymi zakodowaną informację. Dzięki wykorzystaniu technik przetwarzania obrazu i rozpoznawania wzorców możliwa jest implementacja skutecznego systemu globalnego wspomagającego nawigację autonomicznych pojazdów. Prostota systemu pozwala na łatwe jego wdrożenie, bez konieczności przebudowy aparatury monitorującej. Zapewnia również możliwość skorzystania w procesie projektowania z powszechnie dostępnego oprogramowania open source. W artykule przedstawiono algorytm, którego zadaniem jest wyszukanie wprowadzonych do bazy symboli obiektów oraz ustalenie ich pozycji i orientacji w globalnym układzie współrzędnych kamery. Szybkość i niezawodność systemu wykazano na podstawie badań eksperymentalnych z użyciem rzeczywistych robotów mobilnych.
Optical glyphs are non-complex graphic signs that contain encoded information. By utilizing techniques of image processing and pattern recognition, it is possible to implement an effective global system for autonomous vehicle navigation. The simplicity of the system allows it to be easily implemented, without having to rebuild monitoring equipment. It also provides the possibility to use, during the design process, of widely available open source software. This paper presents an algorithm, whose task is to find the symbols of objects contained in the database and determine their position and orientation in the global coordinate system of the camera. The speed and reliability of the system has been demonstrated on the basis of experimental studies using real mobile robots.

Opis:: One of the basic problems connected with wheeled mobile robots is the choice of the appropriate navigational method. This refers to individual robots and also, in particular, the group of mobile robots. “Navigation” can be defined as an issue connected with systems control, defining their position and orientation as well as choosing appropriate trajectory. The consisting elements of mobile robots navigation are: self-localization, path planning and creating a map of the explored area. Each of the above enumerated elements is independent; however, the realization of the target navigation task of the mobile robot or the group of mobile robots depends on the correct construction of particular elements.

Opis:: Artykuł dotyczy systemu nawigacji odruchowej dydaktycznego robota mobilnego MRM.edu. Robot ten powstał w Instytucie Automatyki i Robotyki na Wydziale Mechatroniki Politechniki Warszawskiej. System sterowania pozwala na autonomiczną nawigację odruchową robota. Sposób podejmowania decyzji wzorowany jest na reakcjach organizmów żywych, które pobudzone bodźcem dokonują określonego odruchu. Robot uzyskuje informację o swoim otoczeniu, która staje się dla niego bodźcem do ruchu w odpowiednim kierunku. Specjalnie stworzony algorytm pozwala na poruszanie się wśród przeszkód statycznych oraz dynamicznych, omijanie ich oraz osiągnięcie, początkowo zadanego przez użytkownika, punktu docelowego.
This article refers to reactive-based navigation of MRM.edu didactic mobile robot, which was created at the Institute of Automatic Control and Robotics (Mechatronic Faculty, Warsaw University of Technology). Robot has an autonomous reactive-based navigation system. Decision making pattern imitates live organisms, which stimulated with impulse react in particular manner. Robot obtains environmental information and reacts with proper moves to avoid obstacle collision and to achieve destination coordinates. The navigation system needs only specified target, no environmental information such as: maps or technical description are required. This method is particularly effective in new and even not known surrounding. Example application of this system is autonomous search for explosives in dangerous areas, diagnostics in radioactive environment or exploration of hazardous buildings, caves or ruins. Reactive-based navigation is also useful in dynamic changing surrounding, like crowded corridors, when dislocating obstacles can not be described to robot a priori. System reacts to present state of environment and risk of any collision is less probable.

Opis:: This paper presents a comparative study of Robot Operating System (ROS) packages for mobile robot navigation on an embedded system. ROS provides various libraries and tools in developing complex robot software. We discuss the process of porting ROS to an open embedded platform, which serves as the main controller for a mobile robot. In the case of driving the robot, ROS provides local path planners such as the base, elastic band, and timed elastic band. The local planners are compared and analyzed in terms of accuracy in tracking the global path conducted on a robot model using Gazebo, 3D simulation tool provided by ROS. We also discussed the difference in performance of deploying ROS packages on a personal computer and on the embedded environment. Experiments were performed by controlling two different mobile robots with results showing that tracking error is highly dependent on the goal tolerance. This study will serve as a promising metric in improving the performance of mobile robots using ROS navigation packages.

Opis:: In the area of mobile robotics, trajectory planning is the task to find a sequence of primitive trajectories that connect two configurations, whereas non-holonomic constraints, obstacles and driving costs have to be considered. In this paper, we present an approach that is able to handle situations that require changes of driving directions. In such situations, optimal trajectory sequences contain costly turning maneuvers – sometimes not even on the direct path between start and target. These situations are difficult for most optimization approaches as the robot partly has to drive paths with higher cost values that seem to be disadvantageous. We discuss the problem in depth and provide a solution that is based on maneuvers, partial backdriving and free-place discovery. We applied the approach on top of our Viterbi-based trajectory planner.

Opis:: Path planning plays a vital role in a mobile robot navi‐ gation system. It essentially generates the shortest tra‐ versable path between two given points. There are many path planning algorithms that have been proposed by re‐ searchers all over the world; however, there is very little work focussing on path planning for a service environ‐ ment. The general assumption is that either the environ‐ ment is fully known or unknown. Both cases would not be suitable for a service environment. A fully known en‐ vironment will restrict further expansion in terms of the number of navigation points and an unknown environ‐ ment would give an inefficient path. Unlike other envi‐ ronments, service environments have certain factors to be considered, like user‐friendliness, repeatability, sca‐ lability, and portability, which are very essential for a service robot. In this paper, a simple, efficient, robust, and environment‐independent path planning algorithm for an indoor mobile service robot is presented. Initially, the robot is trained to navigate to all the possible desti‐ nations sequentially with a minimal user interface, which will ensure that the robot knows partial paths in the en‐ vironment. With the trained data, the path planning al‐ gorithm maps all the logical paths between all the des‐ tinations, which helps in autonomous navigation. The al‐ gorithm is implemented and tested using a 2D simulator Player/Stage. The proposed system is tested with two dif‐ ferent service environment layouts and proved to have features like scalability, trainability, accuracy, and repe‐ atability. The algorithm is compared with various classi‐ cal path planning algorithms and the results show that the proposed path planning algorithm is on par with the other algorithms in terms of accuracy and efficient path generation.

Opis:: In thise paper a very simple method of the visual information interpretation for recognition and navigation purposes is presented and discussed. The proposed method consists of six steps: image acquisition, edge detection, fast edge vectorization using a high number of short preliminary vectors, aggregation of the preliminary vectors into the form of final vectors. The next stages of the visualthe visual information interpretation for recognition and navigation purposes will be description of the objects’ shapes by means of the final vectors, object recognition and/or robot navigation on the base of comparison between actual shape description and templates memorized during the programming/training process, but they are not discussed in this paper. The main advantage of the proposed method is a simple and time-effective algorithm, which can be performed in real time also by a simple and cheap processor, working as a “brain” of the considered robot.
