Industrial robot tactile sensors can help industrial robots measure any physical interaction with their environment. Sensors can measure parameters related to contact between sensors and objects. Industrial robots also benefit from touch. Force and tactile sensors enable robots to manipulate objects with higher accuracy and sensitivity in structurally smaller environments.
Tactile sensors are designed based on the biological sensation of their touch and can detect mechanical stimuli, stimulation temperature, and pain. Tactile sensors will receive and respond to signals of force or physical contact.
There are several different tactile sensors in a series of applications, such as sensing normal pressure and dynamic tactile sensing. They are one of the commonly used sensors in robotics technology, including piezoelectric, resistive, capacitive, and elastic types. This article will mainly introduce the functions and types of tactile sensors for industrial robots.
1. Optical tactile sensors: There are two types of optical tactile sensors: internal and external. In this type, the intensity of light is adjusted by moving obstacles to the light path. It has the advantage of anti electromagnetic interference and high resolution. Low wiring is required, and electronic devices can be kept away from sensors.
2. Piezoelectric tactile sensor: When pressure is applied to the sensor element, the voltage effect on the sensor element is called the piezoelectric effect. The generation of voltage is directly proportional to the applied pressure. In this case, no external sensors are required. The advantages of this sensor are durability and wide dynamic range. Can measure pressure.
3. Resistance tactile sensor: The sensor's operation is based on the change in resistance between the conductive polymer and the electrode. This type of tactile sensor is widely used. When pressure is applied, the resistance of conductive materials changes. Then measure the resistance. This sensor has advantages such as high durability and good overload resistance.
4. Capacitive tactile sensor: The capacitance change between two electrodes is used for capacitive sensors. This type of capacitive sensor will measure capacitance and undergo changes under applied pressure. The capacitance of parallel plate capacitors is related to the spacing and area of the plates. Capacitors will vary according to the load. This sensor has the advantages of linear response and wide dynamic range.
5. Magnetic tactile sensor: Magnetic tactile sensors use two methods: one is to measure changes in magnetic flux density, and the other is to measure changes in magnetic coupling deformation between windings. This sensor has the advantages of high sensitivity and no mechanical lag.
The role of industrial robot tactile sensors
In industrial robot operation technology, vision and touch are complementary modes, just like in the human field. Industry experts predict that visual technology will soon be added to mainstream robot applications. Basically, industrial robot tactile sensors are touch sensors that can provide information related to the object they are in contact with. Information is about the shape, size, and type of the touch object.
Industrial robot tactile sensors can detect the presence of objects and other objects. It can also determine the shape, position, and direction of the parts. The contact with the object in contact with the sensor is pressure, so the pressure distribution can be determined. This device can perform inspections on objects, such as texture monitoring, joint inspection, or damage detection. Industrial robot tactile sensors can detect various stimuli, detect the presence of objects, and obtain tactile images. Tactile sensors have many sensitive components. With the help of these components, tactile sensors can measure multiple attributes.
The functional components of industrial robot tactile sensors include a micro switch that is sensitive to different range of motion. It is a touch sensor array that forms a larger sensor called a touch sensor. A separate touch sensor will explain the physical contact between the robot's fingers and the textured surface. Once an industrial robot comes into contact with an object, it will send a signal to the controller.
