With the increase of the degree of intelligence, the robot sensor applications more and more. There are interactive robot intelligent robot, sensing robots and autonomous robots three kinds. Starting from anthropomorphic features, visual, haptic, tactile most important, has already entered the practical stage, there are hearing great progress, there are other smell, taste, feel slippery, etc., corresponding to a variety of sensors, the robot sensing industry has formed production and R & D capability.
The sensor
Mechanical parts or mechanical structure of the machine referred mechatronic products, the sensor and the motor shaft as the arm (Arm), wrist (Wrist) such as the installation together to complete the position, speed, strength measurements, the servo control.
Position (displacement) sensor
Linear movement sensor potentiometer sensor and adjustable transformer two kinds. Angular displacement sensor potentiometer type, adjustable transformer (resolver) and photoelectric encoder three, including photoelectric encoder has incremental encoders and absolute encoders. Incremental encoders are generally used for zero uncertain position servo control, the absolute encoder can be instantaneous shaft angle encoder initial value corresponding to the locked position when the device is subjected to pressure, it suffices to read each joint coding the readings can be servo-controlled setpoint to be adjusted to prevent excessive strenuous exercise when the robot starts.
Robot Sensor Category
Velocity and acceleration sensors
There are two kinds of speed sensors measure the speed of the translational and rotational motion, but in most cases, is limited to measure rotational speed. Use of the derivative of the displacement, in particular, to make the light irradiation method of a photoelectric rotary disk, and the number of pulses detected rotation frequency, rotation angle in order, and the use of a disc made of a slit, through two photodiodes identify the angular velocity, i.e. the speed this is the optical pulse speed sensor. There is also a tachometer generator for speed and so on.
Strain gauges measuring instrument that is scalable, but also a stress sensor for acceleration measurement. An acceleration sensor for measuring the dynamic control signal of an industrial robot. Generally be deduced from the velocity measurement, a known mass object acceleration to generate power, the application of strain gauges measure this force deduction, there is mentioned the following methods:
Related to the acceleration and the measured force can be a known mass production. This force may be an electromagnetic or electrically, to simplify the final measurement of the current, which is returned servo sensor, but also a variety of actual vibration acceleration sensor.
Sound sleep sensor
And explanation for sensing the gas (non-contact feel), liquid or solid (contact feeling) of the acoustic wave. Acoustic wave sensor can detect the degree of complexity from simple to complex sonic presence of acoustic frequency analysis, natural language until successive separate voice and vocabulary to identify.
Contact or non-contact temperature sensor
In recent years, robots used widely, in addition to conventional thermal resistance (thermistor), thermocouple endures, television cameras thermoelectric temperature measurement and sensory images have also made progress.
Slide tactile sensor
For detecting sliding objects. When asked to seize properties robot unknown object, you must determine the most appropriate grip force value, it is required to detect an object slide signal generated enough grip.
There by the optical system of the crystal slip tactile sensor receiver and use slide tactile sensor, which has nothing to do with the sliding direction detection sensitivity.
distance sensor
Distance sensor for intelligent mobile robots: laser range finder (and can be measured angle), sonar sensors in recent years to develop.
Vision Sensor
This is a very broad application of external sensor, in view of its content is very rich, and machine vision often independently formed products, software technology and a very close relationship.
