This paper presents findings from a HRI user-study which investigated participants' perceptions and experiences playing a simple version of the classic game, stone-paper-scissors with a humanoid robot. Participants experienced the robot displaying one of four different robot faces and interacted with the robots using a gesture-based interface. Findings from the study indicated that the effects of the different robot faces were inter-related with participants gender and ratings for overall enjoyment of the game experience. The usability and effectiveness of the gesture-based interface were overall rated positively by participants, though the use of a separate display for the game interface seems to have distracted participants attention from the robot's face. © Copyright IARIA, 2013.

The use of image mosaicing methods for underwater optical mapping has become very popular owing to the rapid progress in obtaining optical data using robotic platforms. In order to obtain globally consistent mosaics, one of the essential steps is global alignment for finding best image registration parameters, which employs non-linear optimisation methods to minimise the error metric defined over correspondences detected between overlapping image pairs. In this paper, we propose a method that uses graph theory principles to reduce the total number of overlapping image pairs used in the global alignment process without degrading the final mosaic quality. This reduction allows for obtaining image mosaics with reduced computational cost and time. The method is validated through two experiments that involve challenging underwater datasets.

This paper presents a railway track and turnout detection and turnout classification algorithm. The railway track extraction is based on an edge detection using the width of the rolling pads. This edge detection scheme is then used as an input to the RANSAC algorithm to determine the model of the rails knowing their gauge. The turnout detection scheme is based on the Histogram of Oriented Gradient (HOG) and Template Matching (TM). The turnout classification is based on HOG. The detection results show (i) reliable performance for our railway track extraction scheme;(ii) a correction rate of 97.31 percent for the turnout detection scheme using a Support Vector Machine (SVM) classifier. The turnout classification has correction rate of 98.72 percent using SVM.

Based on our previous work in the development of a multimodal animated avatar oriented to human-machine interaction and social robotics, a facial expression recognition system is presented in this paper. Both the avatar's architecture and facial recognition system have been oriented to FACS Action Units recognition and generation, so they can be easily integrated. The resulting animated system is able to maintain nonverbal and verbal bidirectional communication, enhancing the interaction with the avatar and making it more natural for the users.

Mobile robotics environments must adopt networking solutions that provide secure and reliable communications for the mobile robots across wide areas such as hospitals, factories, farms, etc. This paper proposes a network architecture for large mobile robotic environments built above the existing networking infrastructures. The architecture builds an overlay network above the already deployed network. The overlay network must fulfill the requirements demanded by mobile robotic applications, mainly, communication continuity during handover, security, and quality of service. A prototype of this architecture was implemented and evaluated in a mobile robotic environment composed of Pioneer P3-DX mobile robots accessed through the Internet. Results from simulation show that the architecture scales well in larger networking scenarios.

This paper presents the architecture and implementation of REALabs-BOT, a WebLab in mobile robotics. REALabs-BOT was designed to run over high speed networks. As such, mobile robotics experiments run on the user's computer and control the robots over the network and in real time. The proposal of the WebLab is to let the student to develop his/her robotic algorithm in Java or Javascript, to tune and evaluate the algorithm in a simulated environment, and finally to run exactly the same algorithm to drive the real robots. REALabs-BOT maintains a repository of robotic experiments for demonstration purposes and as starting point for new experiments. The WebLab also supports secure interaction from multiple users located at different sites. © 2009 IFAC.

A new approach which integrates an omnidirectional vision system, real world devices, such as mobile robots, and an interactive evolutionary interface for sound production, is presented. Starting with an evolutionary composition system named VOX POPULI and later JaVOX, a hybrid environment named AURAL has evolved. It uses curves drawn in a GUI and trajectories produced by mobile robots to modify the fitness function of a real time sonic composition. An arena was constructed to allow the interaction between robots and to control the variations of sonic parameters producing real time MIDI data. The navigation supervisor system, the sonification environment and graphic results of real time experiments are briefly described.
