To verify and evaluate the performance of a space robot controller,kinematics and dynamics of the system have to be formed beforehand for computer *** paper is devoted to develop a new kinematic notation for space robots and to come up with an open source of Matlab subroutines for the propose of obtaining the proper dynamics equations of space robots in symbolic forms *** the new kinematic notation,we will present the general form and two special *** is then demonstrated through an example the advantages such as flexible assignment of frames on space robots,being able to describe multi-DOF joint and achieve a consistent description for multi-arm space *** the second part,we adopt the Lagrangian Formulation for forming the procedures to automatically generate the dynamics equations of space robots in symbolic *** example is then provided to demonstrate the effectiveness of closed-loop simulation adopting the obtained symbolic equations.

Mobile application development has emerged as one of the most focused areas in software industry due to exponential growth of mobile users and applications. The focus of the current mobile industry is on direct implementation, rather than analysis and design. Model-driven engineering practices are ignored, which results in low reusability and lack of portability along with other challenges. In addition, mobile applications also have to support multiple platforms, as an application written for one platform (e.g., Android) cannot run on another platform (e.g., Windows Phone). Each of the platforms in turn suffers from fragmentation. This results in multiple versions of an application that need to be simultaneously maintained. This is a huge burden on the development team, both in terms of cost and effort, due to various platforms that an application supports. This paper proposes a model-driven approach to generate mobile applications for multiple platforms. We carefully identify a subset of UML and propose a modeling methodology for this purpose. We use real use-cases for requirement gathering, class diagram for structural modeling, while state machine are used for behavioral modeling. We focus on modeling business logic layer for the mobile application. We also propose a UML profile for modeling mobile domain specific concepts. Our approach uses Action Language for Foundational Subset of UML (ALF) to specify actions in the state machines. Our approach allows the modeler to automatically generate business logic code for multiple platforms. The approach is supported by an automated tool MAG (Mobile Application Generator). We apply our model-driven approach on an industrial case study 'Scramble' app developed by 'Next In' to demonstrate its viability.

Olfactory-based mobile robots use odors as a guide to navigate and track in the unknown environments. The key issue of localizing the odor plume source is how to trace odor plume effectively. This paper presents an effective olfactory-based planning and search algorithms for using on mobile robots. The algorithms are based on Bayesian inference theory and artificial potential field methods. The Bayesian inference theory is used to construct the probability map of plume source based on the flow records and plume detection information collected from sensors. Then the Artificial Potential Field (APF) method is used for planning a plume tracking path. The robot follows the path to trace odor plume until the source is detected. The algorithms were implemented on a Pioneer 3 Mobile Robot in an indoor airflow environment. Experiment results show that the search algorithms are effective and feasible to odor plume source localization problem.

State-of-the-art gateways are connected to several distributed computing infrastructures (DCIs) and are able to run jobs and workflows simultaneously in all those different DCIs. However, the flexibility of accessing data storages belonging to different DCIs is a missing feature of current gateways. SZTAKI (Institute for computer Science and Control) has developed a Data Avenue Blacktop service and aLiferay-based Data Avenue port let that open the door for integrating such features into science gateways. The paper explains the design considerations of the Data Avenue Blacktop service and its usage scenarios in science gateways through the Data Avenue port let.
