A mobile robot is an automatic machine that is capable of locomotion. Mobile robots have the capability to move around in their environment and are not fixed to one physical location. Mobile robots can be "autonomous" (AMR - autonomous mobile robot) which means they are capable of navigating an uncontrolled environment without the need for physical or electro-mechanical guidance devices. Alternatively, mobile robots can rely on guidance devices that allow them to travel a pre-defined navigation route in relatively controlled space (AGV - autonomous guided vehicle). By contrast, industrial robots are usually more-or-less stationary, consisting of a jointed arm (multi-linked manipulator) and gripper assembly (or end effector), attached to a fixed surface. Mobile robots have become more commonplace in commercial and industrial settings. Hospitals have been using autonomous mobile robots to move materials for many years. Warehouses have installed mobile robotic systems to efficiently move materials from stocking shelves to order fulfillment zones. Mobile robots are also a major focus of current research and almost every major university has one or more labs that focus on mobile robot research.〔P. Moubarak, P. Ben-Tzvi, Adaptive Manipulation of a Hybrid Mechanism Mobile Robot, IEEE International Symposium on Robotic and Sensors Environments (ROSE), Montreal, Canada, 2011, pp. 113 - 118〕 Mobile robots are also found in industrial, military and security settings. Domestic robots are consumer products, including entertainment robots and those that perform certain household tasks such as vacuuming or gardening. == Classification == Mobile robots may be classified by: * The environment in which they travel: * * Land or home robots are usually referred to as Unmanned Ground Vehicles (UGVs). They are most commonly wheeled or tracked, but also include legged robots with two or more legs (humanoid, or resembling animals or insects). * * Delivery & Transportation robots can move materials and supplies through a work environment * * Aerial robots are usually referred to as Unmanned Aerial Vehicles (UAVs) * * Underwater robots are usually called autonomous underwater vehicles (AUVs) * *Polar robots, designed to navigate icy, crevasse filled environments * The device they use to move, mainly: * * Legged robot : human-like legs (i.e. an android) or animal-like legs. * * Wheeled robot. * * Tracks.〔(Rail track ) and (Linear track (PDF) )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mobile robot」の詳細全文を読む スポンサード リンク
