'''Robot sensors''' are used to estimate [[robot]] condition, its environment and passes that signal to robot controller in order to control robot functionality.<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 function of human sensory organs. forFor example, sensors are often intended to mimic the sensory functions of the eyes or skin etc. As such, terminologiesterms like vision, tactile etc., haveand croppedsimilar upterms for other sensory functions are commonly used in robotdiscussion of robotic sensors. Robots, like humans, must gather extensive information about their environment in order to function effectively.
== Part-Picking ==
In a special parts feeder, an alignment pallet areis not necessarily required since an automatic system can be constructed at low cost for alignment operationoperations such likeas vision sensors that perform inspection, pick bins, etc. Insertion [[robot]]s can perform fitting and insertion operation of [[machine]] parts precisely with the help of different kind of [[sensor]]. Different phases' parts are attached by the [[robot]] after matching. ItSuch a robotic system can perform tasks that are beyond from human approach.<ref>{{cite web | url=http://www.universalrobotics.com/random-bin-picking | title=Random Bin Picking & Automated Assembly | publisher=Universal | accessdate=23 January 2015}}</ref>
== Robot Sensation ==
Robot Sensation allowsrefers robotto sensory input allowing robots to measure the distance between objectobjects, the presence of light, the frequency of sound, etc., depending on the type of sensors embedded in the [[robot]].<ref>{{cite web | url=http://www.britishpathe.com/video/robot-sensation | title=Robot Sensation | publisher=British Pathe | accessdate=27 January 2015}}</ref>
Robot can measure:
* Object Proximity: Presence/absence of object, bearing, color, distance between objects.
