The Spring Festival Evening is always accompanied by everyone's various spit, but on the stage of this Spring Festival Evening, there are many things with the characteristics of the new era, such as aerial drones, jumping "the robot aunt of square dance"...
How the robot is on the Spring Festival Evening is actually a false proposition, because the robot is ultimately attributed to the clever human operation...
Speaking of robots, let's talk about Yale University in the United States. They once designed a computer like this: it prepares its own words, and it will demonstrate that it will "think" and to some extent be a bit like a person. With psychology and information theory, scientists have presented themselves with a topic that is amazing to the world: to study the way people think and behave clearly, and then to artificially simulate it.
The square dance robot just after the Spring Festival Gala is based on this kind of robot, so how is this intelligent robot "Aunt" composed?
Composition of the robot
A robot consists of a mechanical part, a sensing part and a control part.
Mechanical part
The mechanical structure of the robot consists of three parts: the fuselage, the arm and the end operator. Each large piece has a number of degrees of freedom to form a multi-degree of freedom mechanical system. According to the mechanical structure, the robot can be divided into a Cartesian coordinate robot, a cylindrical coordinate robot, a polar coordinate robot, an articulated robot, a SCARA robot, and a mobile robot.
Sensing part
It consists of an internal sensor module and an external sensor module that captures useful information in both internal and external environments. The use of smart sensors increases the robot's mobility, adaptability and intelligence. The human perception system is extremely subtle to the perception of the outside world, but for some special information, the sensor is more effective than the human perception system.
Control and drive section
The task of the control system is to control the actuator of the robot to perform the specified movements and functions based on the robot's work instructions and the signals fed back from the sensor. According to the control principle, it can be divided into program control system, adaptive control system and artificial intelligence control system. According to the form of control motion, it can be divided into point control and continuous track control.
The drive system is a device that powers the mechanical structural system. The power source used is different, and the drive system has different transmission modes. There are four main drive modes for the drive system: hydraulic, pneumatic, electric and mechanical. Electric drive is the most widely used drive method. It is characterized by convenient power supply, fast response, large driving force, convenient signal detection, transmission and processing, and can adopt various flexible control methods. Enter the motor or servo motor.
In fact, the reason why such a robot can achieve such a smooth movement is not only the control technology of the microcomputer, but also closely related to the rapid development of the servo motor.
The servo motor system of the robot, the device will quickly transmit to the controller after sensing the external information, and then the controller will send a control signal to drive the servo motor system to quickly adjust the posture. The servo motor system here uses the torque and force generated by various motors to directly or indirectly drive the robot body to obtain various movements of the robot.
The motor industry has undergone a history of precipitation, and it can be said that the motor has been fully integrated into the blood of people's lives. With the improvement of motor quality requirements, the motor testing industry is gradually emerging. Every minute of life is good, and the work of the motor is required to be more accurate. Especially for the current servo motor, in order to ensure that it can be accurately controlled under actual dynamic conditions, the previous test must have a dynamic test link to simulate a dynamic working condition. The remote MPT1000 motor test system was first created. The free-loading engine technology can realize the free dynamic control and transient waveform recording of the system load output, fully satisfying the measurement of the transient waveform and response time of the motor control system, and is the most reliable choice for motor testing.
