'''Robotic sensors''' are used to estimate a [[robot]]'s condition and environment. These signals are passed to a controller to enable appropriate behavior.<ref>{{cite web | url=http://www.robotstorehk.com/sensor.html | title=Automation and Robotics ( Robot Store ) | publisher=Robot Store (HK) | accessdate=23 January 2015}}</ref><ref>{{cite web | url=http://www.active-robots.com/sensors | title=Robotics sensors (Active) | publisher=[[Active Robots]] | accessdate=23 January 2015}}</ref>

Sensors in robots are based on the functions of human [[sensory organ]]s. Robots require extensive information about their environment in order to function effectively.

Line 14 ⟶ 13:

* Simple Vision: [[Edge detection|Detecting edges]], holes and corners.

* Complex Vision: [[Object recognition|Recognizing objects]].

* [[proximity sensor|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.<ref>{{cite web | url=http://www.britishpathe.com/video/robot-sensation | title=Robot Sensation | publisher=British Pathe | accessdate=27 January 2015}}</ref>

Line 21 ⟶ 20:

* 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.<ref>{{cite web | url=http://www.robotplatform.com/knowledge/sensors/types_of_robot_sensors.html | title=Types of Robot Sensors | publisher=Robot Platform | accessdate=23 January 2015}}</ref>

Line 33 ⟶ 31:

[[Position sensor]]s measure the position of a joint (the degree to which the joint is extended). They include:

* [[Encoder (position)|Encoder]]: a digital optical device that converts motion into a sequence of digital pulses.

* [[Potentiometer]]: a variable resistance device that expresses linear or angular displacements in terms of voltage.

* [[Linear variable differential transformer]]: a displacement transducer that provides high accuracy. It generates an AC signal whose magnitude is a function of the displacement of a moving core.

* [[Synchro|Synchros]] and [[Resolver (electrical)|Resolvers]]

=== Velocity Sensor ===

Line 56 ⟶ 54:

* [[Index of robotics articles]]

* [[Mechatronics]]

* [[Outline of robotics]]
