This paper presents a methodology and a concept behind the autonomous navigation which can be used in field robots. Long distance navigation in an outdoor environment is a challenging task owing to floor profile variations and slipping problem. The concept is based on SLAM (Simultaneous Localization and Mapping) GMapping algorithm with particle filter approach in mapping process and AMCL (Adaptive...
A green roof is a roof of a building that is covered from a vegetation. Green roofs are beneficial in number of ways for buildings. Crops in green roofs are exposed to direct solar radiation and strong winds. Furthermore, the substrate is shallow and it can hold limited amount of water. Therefore, artificial irrigation methods are required especially for green roofs in tropical countries. This paper...
Building automation systems has gained huge attraction in building services sector with the development of new concepts in energy conservations. A multifunctional building automation controller has been introduced to cater this demand. The plug-and-play type suggested controlling system consists of two major components; external sensing device and main controlling unit mounted in-house. The external...
Fire detection system in the surveillance system monitors the indoor environment and issues alarm as part of the early warning mechanism with ultimate goal to provide an alarm at early stage before the fire become uncontrollable. Conventional fire detection systems suffer from the transparent delay from the fire to the sensor which is looking at a point. The reliability of the fire detection system...
Interactive robot heads are becoming more and more popular in these days and most of the tasks are replaced by robots in these days. As a solution for neck pain which has become a highly attentive illness nowadays due to use of new technological devices with wrong postures by humans, a humanoid robotic head which acts as an exercise instructor is discussed in this paper. The special features of this...
This paper proposes a method for adapting robot's perception to produce fuzzy vocal responses about the size of an object based on the visual attention of the robot. In a human-human interaction, the humans may use vocal responses, which have qualitative terms such as "small", "large" etc. The actual quantitative meaning of those terms depends on spatial arrangement of the environment...
A vast range of human-friendly interactive robotics heads are developed by researchers. However, the interactive robot heads require improvements in construction and behavior to achieve more human-like interaction. Therefore this paper proposes a design of an interactive robotic head with human-like movements and human-friendly interactive features. The design parameters have been identified by analyzing...
Financial forecasting plays a critical role in present economic context where neural networks have become a good alternative technique over traditional methods. Vast ranges of neural models are developed to achieve better accuracy in forecasting. In addition, the ways to find out a good neural architecture is being explored by the research community. In the literature, main problems are figured out...
This paper proposes a method for interpretation of fuzzy voice commands based on the vocal cues. The fuzzy voice commands include fuzzy linguistic terms like “little” and quantitative meaning of such terms depends on the environmental conditions. Therefore the robot's perception of the corresponding environment is modified by acquiring the user's perception through a series of vocal cues. The user's...
This paper proposes a method for understanding the fuzzy linguistic information based on the user's guidance. A quantitative assessment for a fuzzy linguistic term such as “little” depends on the environmental conditions. Therefore the corrective feedbacks are utilized to adapt the robot's perception toward the corresponding environment. However, the attentive commands like “move carefully” are used...
