This paper addresses an obstacle avoidance issue for redundant nonholonomic mobile modular manipulators. On the basis of modular robot concept, an integrated dynamic modeling method is proposed, which takes both the mobile platform and the onboard modular manipulator as an integrated structure. A new obstacle avoidance algorithm is proposed which is mainly composed of two parts: a self-motion p...

This paper discussed the development of a set of object-oriented modular simulation tools for solving lumped and distributed parameter models generated in process design and simulation. The application of object-oriented design (OOD) and modular approach greatly improves current modeling and simulation capability. Modularized components can be easily integrated/adapted to form a new user-define...

Recent years have seen a growing interest in educational games, which integrate the engaging features of digital games with the personalized learning functionalities of intelligent tutoring systems. A key challenge in creating educational games, particularly those supported with interactive narrative, is devising narrativecentered tutorial planners, which dynamically adapt gameplay events to in...

An assemble to order policy considers a tradoff between the size of product portfolio and assembly lead time. The concept of modular design is often used to implement the assemble to order policy. Modular design impacts assembly of products and the supply chain. In particular storage, transportation and production are affected by the selected modular structure. For a determined assembly lead ti...

Recent research advances in Discrete EVent system Specification (DEVS) as well as cellular space modeling emphasized the need for high performance modeling methodologies and environments. The growing demand for cellular space models has directed researchers to use different implementation formalisms. Many efforts were dedicated to develop cellular space models in DEVS in order to employ the adv...

This paper presents a practical method for automatic tip-over prevention and path following control of a redundant nonholonomic mobile modular manipulator. According to modular robot concept, the mobile platform is treated as a special module attached to the base of the modular manipulator, then an integrated structure is constructed and its dynamic modeling is performed. A new tip-over stabili...

An alternative approach to multi-region modeling will be presented. This approach (called modular approach) is able to reproduce results obtained with the traditional as well as a modified Negishi approach. We redesigned the Negishi approach to make it applicable in modeling technological spillovers induced by foreign direct investments. While the modular approach is able to completely internal...

This research was initiated to learn what the crop modeling community could do to facilitate an evolution from existing crop models toward more modular ones that can meet increasing demands. Specific objectives are to 1) use UML to design and implement a modular crop model using an object oriented language, and 2) to compare the characteristics of this model and its development with a modular m...

Software reliability growth models (SRGM) are used to assess modular software quantitatively and predict the reliability of each of the modules during module testing phase. In the last few decades various SRGM’s have been proposed in literature. However, it is difficult to select the best model from a plethora of models available. To reduce this difficulty, unified modeling approaches have been...
