1. Proximity sensing.
Proximity usually refers to exploration:
a. Whether the target exists.
The scale or abbreviated shape of an object.
Proximity sensors can be divided into touch, non-touch, and imitation. The choice of sensor depends on physical, environmental, and control conditions.
Machine:
Appropriate mechanical/electrical switches can be used, but micro switches are generally used because of the amount of force required to operate them.
Pneumatic:
This proximity sensor damages or disturbs air activity. A compressed air proximity sensor is an example of a point sensor. However, this product cannot be used for light parts that may be blown away.
Optics:
In the simplest way, optical proximity sensors cut off the beam and drop it onto a device like a photocell. This is an example of a wrong touch sensor. It should be noted that these sensors are to be used with special care in lighting environments. For example, optical sensors can be shielded due to flashes of light during arcing, while dust and smoke in the air can interfere with light transmission
Electric:
Contact sensors can be divided into touch type and non-touch type. By forming a complete circuit between the sensor and the element, a simple touch sensor can be completed, and the pointless electrical proximity sensor is based on the Leary inductance principle to detect metal or non-metal.
Range Sensing:
Although it can also be used as a proximity sensor, it can detect the position of the proximity sensor when the proximity sensing touches. Non-touch mimicry skills are used for distance or distance sensors, using capacitive, inductive, and sulfonomic skills to complete short-range sensing between a few millimeters and hundreds of millimeters, and remote sensing uses different types of emitted waves (such as radio wave steering waves and lasers)
2. Force sensing
The six forces may be inductive, and whatever the situation is, the applied force may be static, static, or stated. The effect force is because it has to prescribe magnitude and direction together. Therefore, the force sensor is an imitation of operation, sensitive to the direction of operation, six effect forces:
(1) Pull
(2) Compressive force
(3) Shear force
(4) Change force
(5) Bending force
(6) Friction
People are able to feel a lot of skills, some direct, some direct.
Tensile Force:
The change in resistance can be obtained by increasing the length of the transformer. The change in resistance measured by this type of instrument can be converted into force, so it is a direct device.
Pressure:
The device can be determined by detecting the change of battery size under load reduction, the increase of battery pressure under load, or the change of electric positive under load reduction
Changing Force:
Combining tension and compression forces can combine the above.
Frictional force:
This includes constrained movements, so that friction is directly detected by the combination of selective force and motion sensors. For example: 3. Tactile sensing.
The sense of touch is felt through the sense of touch. The abbreviated type of touch sensor is a simple set of touch sensors. This is commonly referred to as a matrix sensor.
Each individual sensor is activated when it touches an object, and by detecting which sensor is a live digital), perhaps the output signal (the size of the mold), it is possible to determine the imprint of the component, and the size and shape of the imprinted element can be determined by comparing the information before and before imprinting.
Mechanical, light, and electrotactile sensors were completed. Tactile sensors
4. Thermal sensor
Thermal sensors may be part of the process control, or maybe part of the safety control. There are many ways to choose, depending on the temperature you want to test. Commonly used methods are: bimetal strips, thermocouples, resistance thermometers, or thermistors. Infrared imaging skills can be applied to more chaotic low-heat systems.
5. Auditory (auditory)
Acoustic sensors can sometimes detect and distinguish a wide range of sounds. It can be used for voice recognition, voice commands, and perhaps to identify unusual sounds such as explosions. Microphones are the most commonly used sound wave sensors.
In industrial environments, the most obvious problem with acoustic sensors is the high volume of background noise. The acoustic sensor can be easily conditioned so that it only responds to specific frequencies to distinguish between different noises.
6. Gas Sensing (Odor)
A gas or smoke sensor relies on a chemical change in the substance contained in the sensor to physically expand the gas or smoke sensor and perhaps generate enough heat to trigger the switchgear
7. Machine Vision (Scope)
Visualization is one of the most active areas of research on robotic sensory responses
Machine vision is a way to convert real-time images captured by a camera into computer system analysis. This change generally refers to the transformation of an image into a numerical category that is understood by a computer. Drawing collection, numerical and data analysis are necessary throughout the process
It is very agile, so that the robot system can react to the dissected drawings and take the appropriate steps when performing the task.
Improving the robot's vision capabilities will unleash the full potential of industrial robots for artificial intelligence. Its effects encompass the exploration of presence, position and movement, the identification and identification of different components, styles and characteristics.
However, even the most rudimentary visual skills require a lot of memory and a long amount of time to take care of them
