In this paper we present an approach for using vision as the primary source of sensing to guide a mobile robot in an unknown environment. We define a set of primitive visual behaviours for navigating a mobile robot in realtime. By combining such behaviours with a purposive map, our mobile robot exhibits a goal seeking behaviour. We present a fast segmentation technique for vision processing. Th...

Mobile robot localization and map building are very important for a mobile robot to perform a navigation-based service task to aid the aged or disabled in an indoor environment (office, facilities or at home). In order to enable mobile robot to perform service tasks autonomously, the information of environment in which the mobile robot moves is needed. To obtain the accurate map, many different...

Mobile robots are used to operate in urban environments, for surveillance, reconnaissance, and inspection, as well as for military operations and in hazardous environments. Some are intended for exploration of only natural terrains, but others also for artificial environments, including stairways. This paper presents a mobile robot design that achieves autonomous climbing and descending of stai...

One of the standing challenging aspects in mobile robotics is the ability to navigate autonomously. It is a difficult task, which requiring a complete modeling of the environment. This paper presents an intelligent navigation method for an autonomous mobile robot which requires only a scalar signal like a feedback indicating the quality of the applied action. Instead of programming a robot, we ...

Generally speaking, the mobile robot is capable of sensing its surrounding environment, interpreting the sensed information to obtain the knowledge of its location and the environment, planning a real-time trajectory to reach the object. In this process, the issue of obstacle avoidance is a fundamental topic to be challenged. Thus, an adaptive path-planning control scheme is designed without de...

Mobile robots can replace humans in variety of different tasks. Although mobile robots can perform tasks safer, quicker, more efficient, more precise etc. than human, the accurate localization system is a must for successful mobile robot operation in the working environment. According to literature mobile robots can help a lot in the agriculture industry where time consuming, tiring, routine an...

The goal of mobile robotics research has been to establish effective ways for a mobile robot to navigate from one place to another. This thesis documents an experimental investigation into the use of vision for the navigation of mobile robots. The research presented in this thesis was directed at achieving qualitative navigation in an unmodified, unknown and dynamic environment. This thesis des...

Latest advances in hardware technology and state of the art of mobile robot and artificial intelligence research can be employed to develop autonomous and distributed monitoring systems. And mobile service robot requires the perception of its present position to coexist with humans and support humans effectively in populated environments. To realize these abilities, robot needs to keep track of...

The goal of this research was to develop a fuzzy obstacle avoidance system for an autonomous mobile robot using IR detection sensors. This paper presents implemented control architecture for behavior-based mobile robot. The mobile robot is able to interact with an unknown environment using a reactive strategy determined by sensory information. Current research in robotics aims to build autonomo...

With the continuous development of intelligent robotics, intelligent robot can realize autonomous moving. Robot simultaneous localization and mapping technology arises at the historic moment. Adaptive monte carlo localization algorithm was used for mobile robot pose estimation. Bayesian algorithm was used to building grid map. The robot moving path was computed by the path planner algorithm. Th...
