Arrays of [[tactile sensor|tactels]] can be used to provide data on what has been touched. The [[Shadow Hand]] uses an array of 34 tactels arranged beneath its [[polyurethane]] skin on each finger tip.<ref>{{Cite web|url=http://www.shadowrobot.com/hand/techspec.shtml|title=Shadow Robot Company: The Hand Technical Specification|access-date=2009-04-09|url-status=dead|archive-url=https://web.archive.org/web/20080708193055/http://www.shadowrobot.com/hand/techspec.shtml|archive-date=2008-07-08}}</ref> Tactile sensors also provide information about forces and torques transferred between the robot and other objects.

[[Computer vision|Vision]] refers to processing data from any modality which uses the electromagnetic spectrum to produce an image. In humanoid robots it is used to [[Object recognition|recognize objects]] and determine their properties. Vision sensors work most similarly to the eyes of human beings. Most humanoid robots use [[Charge-coupled device|CCD]] cameras as vision sensors.

Sound sensors allow humanoid robots to hear speech and environmental sounds, akin to the ears of the human being. [[Microphone]]s are usually used for the robots to convey speech.
