Robotic sensors are used to estimate a robot's condition and environment. These signals are passed to a controller to enable appropriate behavior.〔(【引用サイトリンク】 title=Automation and Robotics ( Robot Store ) )〕〔(【引用サイトリンク】 title=Robotics sensors (Active) )〕 Sensors in robots are based on the functions of human sensory organs. Robots require extensive information about their environment in order to function effectively. == Classification == Sensors provide analogs to human senses and can monitor other phenomena for which humans lack explicit sensors. * Simple Touch: Sensing an object's presence or absence. * Complex Touch: Sensing an object's size, shape and/or hardness. * Simple Force: Measuring force along a single axis. * Complex Force: Measuring force along multiple axes. * Simple Vision: Detecting edges, holes and corners. * Complex Vision: Recognizing objects. * Proximity: Non-contact detection of an object. Sensors can measure physical properties, such as the distance between objects, the presence of light and the frequency of sound.〔(【引用サイトリンク】 title=Robot Sensation )〕 They can measure: * Object Proximity: The presence/absence of an object, bearing, color, distance between objects. * Physical orientation. The co-ordinates of object in space. * Heat: The wavelength of infrared or ultra violet rays, temperature, magnitude, direction. * Chemicals: The presence, identity, and concentration of chemicals or reactants. * Light: The presence, color, and intensity of light. * Sound: The presence, frequency, and intensity of sound.〔(【引用サイトリンク】 title=Types of Robot Sensors )〕 Motion controllers, potentiometers, tacho-generators and encoder are used as joint sensors, whereas strain-gauge based sensing is used at the end-effector location for contact force control. 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「robotic sensors」の詳細全文を読む スポンサード リンク
