Recently, various types of robots have been researched and developed for supporting our life. Also, the perceptual system for the robot is researched. Visual perception includes a lot of valuable information and it is useful for all intelligent robot system. In this paper, we discuss intelligent robot vision in order to detect multiple object and human. There are many visual sensors and we use the...
A new algorithm based on modified particle swarm optimization (MPSO) which follows a local gradient of the chemical concentration within a plume and follow direction of the wind velocity is investigated. Moreover, the niche or parallel search characteristic is adopted on MPSO to solve the multi-peak and multi-source problem. When using parallel MPSO, subgroup of robot is introduced then each subgroup...
This paper describes an approach for real time detection and evaluation of region of interest (ROI) based on saliency and relevance. In our approach, we have considered moving background updating technique to adapt with real environment with camera equipped with mobile robot. We have introduced a new decision making criterion which selects the relevant objects based on human psychology of relevance...
This paper deals with a cooperative object tracking with mobile robotic sensor network. The occlusion problem, which is one of the most important problems of mobile object tracking, will be solve with utilizing the mobile robotic sensor network. Additionally, the high quality information of the object can be observed, since the robotic sensor network can change observation formation their own way...
A three-wheeled omni-directional cane robot is designed for aiding the elderly walking. A new human fall detection method is proposed based on fusing sensory information from a vision system and a laser ranger finder (LRF). This method plays an important role in the fall-prevention for the cane robot. The human fall model is represented in a 2D space, where the distance between the head and the average...
A three-wheeled omni-directional cane robot is designed for aiding the elderly walking. Possible move modes are analyzed and a corresponding hybrid model is constructed to describe walking behavior. A concept called intentional direction is presented to denote the moving intention of a human. Based on experiments and some assumptions, dynamic model of intentional direction is obtained as well as its...
This paper provides a combination of chemotaxic and anemotaxic modeling, known as odor-gated rheotaxis (OGR), to solve real-world odor source localization problems. Throughout the history of trying to mathematically localize an odor source, two common biometric approaches have been used. The first approach, chemotaxis, describes how particles flow according to local concentration gradients within...
