Omni directional mobile robots have been popularly employed in several applications especially in soccer player robots considered in Robocup competitions. However, omni directional navigation system, omni-vision system and omni-kick mechanism in such soccer player robots have not ever been combined. This situation brings the idea of a robot with no head direction into existence, i.e. a comprehe...

in this paper, an intelligent controller is applied to control omni-directional robots motion. first, the dynamics of the three wheel robots, as a nonlinear plant with considerable uncertainties, is identified using an efficient algorithm of training, named lolimot. then, an intelligent controller based on brain emotional learning algorithm is applied to the identified model. this emotional lea...

Map information is important for path planning and self-localization when mobile robots accomplish autonomous tasks. In unknown environments, mobile robots should generate an environment map by themselves. Then, we propose a method for construction of the 3D environment model by a mobile robot. The method is based on structure from motion. We use a single omni-directional camera to measure the ...

Mobile robots with omni-directional wheels can generate instant omni-directional motion including lateral motion without any extra space for changing the direction of the body. So, they are capable of traveling in every direction under any orientation to approach their destinations even in narrow aisles or tight areas. Especially, if a construction tool is combined to the mobile robot, it can b...

While navigating, most autonomous mobile robots view things only in front of them and, as a result, they may collide with objects moving from the side or behind. To overcome this problem, an Active Omni-directional Range Sensor System has been presented, that is capable of obtaining the omni-directional range data on navigation environment through the use of a laser conic plane and a conic mirr...

In recent years, mobile robots are expected to perform various tasks in general environments such as nuclear power plants, large factories, welfare care facilities and hospitals. However there are narrow spaces with vertical gaps made by two horizontal floors in such environments and it is difficult for general car-like vehicles to run around there. Generally, the mobile robots are required to ...

A lot of plumbings exist in factories and so on. It is difficult for humans to inspect them directly. Therefore, automated inspection by robots is desirable. However, many of existing inspection robots have to rotate the camera because a conventional camera can see only one direction while a piping has a cylindrical geometry. The use of an omni-directional camera is effective for the solution o...

In this paper, we propose a decentralized motion control algorithm of multiple mobile robots transporting a single object in cooperation with a human based on a path generated from an environment. Each mobile robot is controlled as if it has a wheel with a free rotational joint and moves along the path based on the intentional force applied by a human. The proposed decentralized control algorit...

Traditional two wheels differential drive normally used on mobile robots have manoeuvrability limitations and take time to sort out. Most teams use two driving wheels (with one or two cast wheels), four driving wheels and even three driving wheels. A three wheel drive with omni-directional wheel has been tried with success, and was implemented on fast moving autonomous mobile robots. This paper...
