'''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 32 ⟶ 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]]
