Industrial robots have penetrated into all walks of life, helping people to complete welding, handling, spraying, stamping and other tasks, so you have thought about how the robot is to do some of this?What about its internal structure?Today we will take you to understand the structure and principle of industrial robots.
The robot can be divided into hardware part and software part, the hardware part mainly includes the ontology and controller, and the software part mainly refers to its control technology.
I. Ontology part
Let’s start with the body of the robot.Industrial robots are designed to resemble human arms.We take HY1006A-145 as an example. In terms of appearance, there are mainly six parts: base, lower frame, upper frame, arm, wrist body and wrist rest.
The robot’s joints, like human muscles, rely on servo motors and decelerators to control movement.Servo motors are the source of power, and the running speed and load weight of the robot are related to the servo motors.And the reducer is the power transmission intermediary, it comes in many different sizes.In general, for micro robots, the required repetition accuracy is very high, generally less than 0.001 inch or 0.0254 mm.The servomotor is connected to the reducer to help improve accuracy and drive ratio.
Yooheart has six servomotors and decelerators attached to each joint that allow the robot to move in six directions, what we call a six-axis robot.The six directions are X- forward and backward, Y- left and right, Z- up and down, RX- rotation about X, RY- rotation about Y, and RZ- rotation about Z.It is this ability to move in multiple dimensions that allows robots to strike different poses and perform various tasks.
The controller
The controller of the robot is equivalent to the brain of the robot. It participates in the whole process of calculating the sending instructions and energy supply. It controls the robot to complete certain actions or tasks according to the instructions and sensor information, which is the main factor determining the function and performance of the robot.
In addition to the above two parts, the hardware part of the robot also includes:
- SMPS, switching power supply to provide energy;
- CPU module, control action;
- Servo drive module, control the current to make the robot joint move;
- The continuity module, equivalent to the human sympathetic nerve, takes over the robot’s safety, rapid control of the robot and emergency stop, etc.
- The input and output module, equivalent to the detection and response nerve, is the interface between the robot and the outside world.
Control technology
Robot control technology refers to the rapid and accurate operation of a robot application in a field.One of the advantages of robots is that they can be easily programmed, which allows them to switch between different scenarios.In order to enable people to control the robot, it must rely on the teaching device to carry out.On the display interface of the teaching device, we can see the programming language HR Basic of the robot and various states of the robot.We can program the robot through a teaching device.
The second part of the control technique is to control the movement of the robot by drawing a table and then following the chart.We can use the calculated mechanical data to complete the planning and motion control of the robot.
In addition, machine vision, and the more recent craze for artificial intelligence, such as immersive deep learning and classification, are all part of the control technology category.
Yooheart also has a research and development team dedicated to the control of the robot.In addition, we also have the mechanical systems development team responsible for the robot’s body, the control platform team responsible for the controller, and the application control team responsible for the control technology.If you are interested in industrial robots, please check out the Yooheart website.
