Editing Autonomous robot (section)

=== Sensing the environment ===
Exteroception is [[robotic sensing|sensing]] things about the environment. Autonomous robots must have a range of environmental sensors to perform their task and stay out of trouble. The autonomous robot can recognize sensor failures and minimize the impact on the performance caused by failures.<ref>{{Cite journal |last=Ferrell |first=Cynthia |date=March 1994 |title=Failure Recognition and Fault Tolerance of an Autonomous Robot |url=http://dx.doi.org/10.1177/105971239400200403 |journal=Adaptive Behavior |volume=2 |issue=4 |pages=375–398 |doi=10.1177/105971239400200403 |s2cid=17611578 |issn=1059-7123}}</ref>

*Common exteroceptive sensors include the [[electromagnetic spectrum]], sound, touch, chemical (smell, odor), temperature, range to various objects, and altitude.

Some robotic lawn mowers will adapt their programming by detecting the speed in which grass grows as needed to maintain a perfectly cut lawn, and some vacuum cleaning robots have dirt detectors that sense how much dirt is being picked up and use this information to tell them to stay in one area longer.
