To work as effectively as between robot and external conditions for the feeling of discriminant function is indispensable. Did not feel the function of the original robot, can according to the prescribed order, repeatedly for a certain action. If have feeling, can according to the processing of the change of the object changes, eliminate mixed with other objects, for example, messy position can be adaptive to a certain artifacts and grabbed the object, and so on. At the same time, if can use some sensory perception information performed their work results, can learn better work method according to experience, thus the work can be familiar.

The feeling of people with visual, hearing, touch, smell, taste, feel balance, etc. These feelings in human average life enter the proportion of outside information, visual maximum (). Similarly, the visual is important for robot to adapt to the environment, rely on outside some visual sensor has become the important engineering topics.

Visual, usually, are mostly rely on outside shooting TV cameras or CCD and its signal processing device, usually visual mostly by shooting TV cameras or combination of the outside world, as the center of the computing device is a digital computer. The center of the computer vision technology including camera image smoothing and enhancement, image processing technology such as regional segmentation, found in the image object and distinguish identify its type or the location of the pattern recognition technology, etc.

Visual is important in a person's feeling after hearing, but not so valued in the industrial robot. This is because the purpose of the auditory co., LTD., is not essential for the robot control technology. But in the future, with the further development of voice processing technology, from the use of voice command, control, robot as the point of view of man-machine interface, its importance is increasing. In addition, in the atomic reactor or extreme work area such as the scene of the fire work of robot, the hearing test is very useful.

Is most closely related with the control of robot tactile. Vision is suitable for the existence of object detection and to detect the state of position and posture of the roughly. Touch, by contrast, to assist the visual, can detect objects more subtle, and can be used to repeat that the real-time control of real-time detection and correction action. The feeling of other, such as taste, smell, etc., in addition to detect gas special occasions like that, the more common detection method is not very good.

Through the sense organ for environment information, through the analysis of the information, so as to adapt to the environment. Similar to person, robot also need to get the information to the flexibility to adapt to the environment of the surroundings. Sensory information obtained by robot sensors. Made environmental data from the sensor, through the analysis of the data processing to form the correct understanding of the objective world, which provide the basis for mission and deal with emergency. Industrial robot sensory systems including sensor system, and analyze the sensor data processing and the correct data object is two parts.
