A team of robots and an exploratory mission are modeled as a multiagent planning problem in a decentralized decision theoretical framework. In this application domain, agents are constrained by resources such as their remaining battery power. In this context, there is an intrinsic relation between collaboration, computation and the need for the agents to observe their resource level. This paper reports on an empirical study of this relationship.

Achieving rapid, intuitive, and error-free robot setup and instruction is a challenge. We present our work towards an assistive infrastructure for robot setup and instruction that attempts to address it. In this paper, we describe the ongoing development of a system that automatically generates multimodal dialogue interaction from product and process ontologies. The prototype currently generates two modalities, digital paper and spoken dialogue.

This paper presents a novel vision based approach to identify utterances consisting of consonants. A view based method is adopted to represent the 3-D image sequence of the mouth movement in a 2-D space using grayscale images named as motion history image (MHI). MHI is produced by applying accumulative image differencing technique on the sequence of images to implicitly capture the temporal information of the mouth movement. The proposed technique combines Discrete Stationary Wavelet Transform (SWT) and image moments to classify the MHI. A 2-D SWT at level 1 is applied to decompose MHI to produce one approximate and three detail sub images. The paper reports on the testing of the classification accuracy of three different moment-based features, namely Zernike moments, geometric moments and Hu moments computed from the approximate representation of MHI. Supervised feed forward multilayer perceptron (MLP) type artificial neural network (ANN) with back propagation learning algorithm is used to classify the moment-based features. The performance and image representation ability of the three moments features are compared in this paper. The preliminary results show that all these moments can achieve high recognition rate in classification of 3 consonants.

We present in this paper several ideas about the usability of the robotic arms and mobile robots as an assistive technology in a smart house where people with disabilities daily live. First, psychological and social aspects of smart home technology are presented and after that the modularity and standardization processes are discussed. Next we propose a smart house plan, equipped with a mobile robot which has a manipulator arm. This robotic system is used to help vulnerable persons, the handicapped men vehicle seat being equipped with a robotic arm which can manipulate objects by a hyper-redundant gripper. For the control of the processes in the smart house, we propose a hierarchical control system and for the mobile robot we use the artificial potential field method. Also, this paper points out the edutainment concept (EDUcation and enterTAINMENT) by robotics. Finally, some applications are presented.

In this paper, a Perceptual Motor Control Model(PMCM) based on output feedback adaptive control theory is considered from the viewpoint of voluntary movement such as hand-tracking control. We give an account of the PMCM structure using together with both of the output feedback controller designed by using an almost strict positive real characteristics for the controlled plant and the Smith predictor for plant with pure time delay. In the proposed method, the attractive structural similarity exists between the cerebrum-cerebellum neuro-motor signal feedback loop and the adaptive controller compensators local minor feedback loop. The proposed perceptual motor control model is evaluated through the comparison of between the experiment and the simulation of for handling 1-link mechanism in order to track an indicator.

The ability of robots to quickly and accurately localize their neighbors is extremely important for robotic teams. Prior approaches typically rely either on global information provided by GPS, beacons and landmarks, or on complex local information provided by vision systems. In this paper we describe our trilateration approach to multi-robot localization, which is fully distributed, inexpensive, and scalable [15]. Our prior research [14] focused on maintaining multi-robot formations indoors using trilateration. This paper pushes the limits of our trilateration technology by testing formations of robots in an outdoor setting at larger inter-robot distances and higher speeds.

Indoor structured environments contain an important number of planar surfaces and line segments. Using these both features in a unique map gives a simplified way to represent man-made environments. Extracting planes and lines by a mobile robot requires more than one sensor: a 3D laser scanner and a camera can be a good equipment. The incremental construction of such a model is a Simultaneous Localisation And Mapping (SLAM) problem: while exploring the environment, the robot executes motions; from each position, it acquires sensory data, extracts perceptual features, and simultaneously, performs self-localisation and model update. First, the 3D range image is segmented into a set of planar faces which are used as landmarks. Next, we describe how to extract 2D line landmarks by fusing data from both sensors. Our stochastic map is of heterogeneous type and contains plane and 2D line landmarks. At first, The SLAM formalism is used to build a stochastic planar map, and results on the incremental construction of such a map are presented, further on, heterogeneous map will be constructed.

Programming industrial robotic workcells is a challenging task, namely because it means dealing with several types of machines, mange the data flow between them and orchestrate their basic functionality into a working program. In this work service oriented architectures are used for the task of programming robotic workcells along with managing the communication between cell components, and a statechart model engine is implemented to orchestrate the system logic. The objective of this paper is to focus in merging service oriented architectures with StateCharts XML, and in evaluating that robotic workcell programming approach using a simple laboratory test bed.
