This paper presents a local/global frames switching in outdoor navigation of a four-wheeled mobile robot in an obstructed environment. Two laser range finders are equipped on the mobile robot in order to perform sensor-based obstacle avoidance without any a priori knowledge about its environment. Also, a GPS is mounted on the top of the robot so that the absolute location and the heading angle of...
Recently, mobile indoor robots have been intensively studied. When such mobile robots are operated, it is necessary to generate their trajectory automatically. In this study, a system which automatically generates the target trajectory avoiding obstacles in the indoor environment by real-time optimization is developed. Conventional artificial potential field method directly generates force which leads...
Important advances have been made in the last period in the robotic domain. Mobile robots are in an accentuated development. The navigation of the mobile robots requires solutions for the following problems: the establishment of the current position, the motion planning and the avoidance of obstacles. This paper approaches the problem of indoor navigation of a wheeled mobile robot. The X80 robot from...
