the authors developed user recognition system for navigation robot. This system is used to prevent navigation robot mistaking user. It uses ZigBee-3D acceleration sensor and kinect sensor. The ZigBee coordinator which is mounted navigation robot know that user comes near to navigation robot by finding the ZigBee accelerometer tag which is attached a user. This tag has unique ID each other, so t...

] I[ Abstract This paper delcribes fuzzy logic techniques used in a hierarchical behavior-based architecture for robot navigation. An architectural feature for threshold activation of fuzzy. behaviors is emphasized, which is potentially useful for tuning navigation performance in real world applications. The target application is autonomous local navigation of a small planetary rover. Threshold...

This study aims to investigate the gender differences in spatial navigation using the tasks of 2-D matrix navigation and recognition of real driving scene. The results can be summarized as followings. First, female subjects responded faster in 2-D matrix navigation task than male subjects when landmark instructions were provided. Second, in recognition task, male subjects recognized the key ele...

EDUCO is a system for collaborative learning that uses real-time direct social navigation. Social navigation means making the navigation of other users visible to everyone else in the system. The paper discusses the social navigation features of EDUCO and reports empirical results regarding the collaborative behaviour of the students in a university-level Web-course. Contrary to our research hy...

In the past decade, a large number of robots have been built that explicitly implement biological navigation behaviours. We review these biomimetic approaches using a framework that allows for a common description of biological and technical navigation behaviour. The review shows that biomimetic systems make signi cant contributions to two elds of research: First, they provide a real world test...

Although satellite navigation, mainly based on the U.S. GPS, plays an important role in positioning and navigation tasks and although there are efforts to establish new satellite-based navigation systems like the European Galileo, the reliability and availability of these systems cannot satisfy all requirements of today’s navigation. Therefore, the navigation system of the future will likely co...

Successful intelligent land vehicle navigation systems can only be realised through the integration of navigation data and spatial information. This is evident in the development of modern Intelligent Transportation Systems (ITS), where the Global Positioning System (GPS) is used to provide the navigation data, and spatial information contained within an information database is used to provide ...

Autonomous mobile entity navigation through dynamic and unknown environments is an essential part of many mission critical applications like search and rescue and fire fighting. The dynamism of the environment makes it particularly difficult to achieve navigation using just on-board sensors and existing navigation methods. This motivates the integration of wireless sensor networks with navigati...

To improve applicability and adaptability of the impact time control guidance (ITCG) in practical engineering, a two-stage ITCG law with simple but effective structure is proposed based on hybrid proportional navigation, namely, pure-proportional-navigation retro-proportional-navigation. For case error less than zero, first stage guided trajectory driven by retro-proportional-navigation second ...

Web page (see Figure 36.2; b-3) representing the possible navigational targets (Tasks, Reports, and Contacts). However, as the label connected as, represented by the navigational link LI96 is a source link (empty arrow), the login information is showed in the same user’s generated home page (see Figure 36.2; b-3). The following usability metrics can be applied to the Navigational Model in Figur...
