An industrial robot is a multifunctional machine that can be operated automatically and can be reprogrammed to change. It has multiple degrees of freedom and can be used to move materials, parts, and hold things to complete a variety of different jobs.
1. The composition of industrial robots
Industrial robots are generally composed of executive organization, drive-drive system, control system and intelligent system.
2. Functions of each part of the robot
Execution organization: It is the main part of the robot to complete various tasks. Generally, it is an open space linkage organization.
Drive-drive organization: It is composed of a drive and a transmission organization. The transmission has mechanical, electrical, hydraulic, pneumatic and compound type. The drives have stepper motors, servo motors, hydraulic motors and hydraulic cylinders.
Control system: It is generally composed of a teaching operation panel or a control computer and a servo control device. The function of the former is to announce the instructions to harmonize the movements between the various drives involved, together with the programming, teach-in/reproduce, and other environmental conditions (sensor signals) and process requirements. Information transfer and harmonious operation between external related devices. The latter is to manipulate the joint drive so that the rod can move according to the predetermined movement rules.
Intelligent system: It is composed of a perception system and an analysis and decision-making system, which are completed by sensors and software respectively.
3. Robot manipulator
The mechanical structure part of an industrial robot is called a manipulator. It consists of a frame, waist, arms, arms, wrists, and hands. That is, it is composed of arm tissue and wrist tissue.
4. The development process of industrial robots
The first generation is a teach-in/reproduction robot. It is mainly composed of a mechanical system and a control system. At that time, it was the most widely used in industry.
The second generation of robots is sensory robots. Such as force, touch, and vision, it has the ability to respond to certain external signals. It is now in the application stage.
The third generation is an intelligent robot. It is still in the stage of thorough research.
5. The main type of manipulator: Cartesian coordinate type; cylindrical coordinate type; spherical coordinate type; Articular.
7. The main technical objectives of the manipulator
(1) Degrees of freedom
Degrees of freedom is the number of independent parameters used to confirm the orientation and posture of the hand relative to the machine base, which is equal to the number of joints that are independently driven by the manipulator.
Degrees of freedom are an important goal to reflect the versatility and adaptability of the manipulator. At present, most of the general industrial robots are about 5 degrees of freedom, which can meet the requirements of a variety of operations.
(2) Working space: that is, the operating range of the manipulator.
(3) Sensitivity: Sensitivity refers to the number of postures that the actuator at the end of the manipulator can adopt when working (such as grabbing objects). If the object can be grasped from all directions, its sensitivity is the greatest; If the object can only be grasped from one direction, it is least sensitive.
7. Confirm the orientation and posture of the manipulator
(1) Depiction of the orientation and posture of the operator
The spatial orientation and pose of the component are depicted using the square array rij and pose matrix Rij of the component, or the orientation matrix Mij of the component.
(2) The azimuth matrix between the two rods
The pose matrix Mi-1,i relative to rod i and rod i-1 is the transition matrix of coordinate system i relative to coordinate system i-1, and this method is called D-H method.
8. Establish and solve the orientation equation of the operator
(1) Establishment of the position and attitude equation of the operating machine
The pose matrix equation of the manipulator i is: M0i=M01M02... Mi-1,i, that is, the equation of motion of the manipulator.
(2) Solving the pose equation of the operating machine
There are two basic types of problems with the pose analysis of the end actuator of the robot manipulator:
1) The positive solution of the pose equation
Knowing the motion parameters of each joint, find the orientation and posture of the end actuator relative to the coordinate system.
2) The inverse solution of the pose equation
According to the given satisfactory job requirements, the end actuator is relative to the orientation and posture of the coordinate system, and the motion parameters of each joint are obtained.
This is the key to the control of the machine, so that the end actuator can only achieve the desired orientation and posture by making the joints move according to the inverse solution.
9. Planning of industrial robot operation organization
An industrial robot manipulator is a mechanical device composed of a machine base, an arm, a wrist and a end actuator. From the perspective of the way the robot completes the operation, the manipulator is composed of arm tissue, wrist tissue and end actuator. Its structural scheme and its motion planning are the key to the whole robot planning.
(1) Planning of the manipulator arm organization
The arm tissue is generally 2-3 degrees of freedom, and it is required to be able to complete three forms of movement: reversal, pitching, lifting or elasticity. When planning the arm tissue, it is necessary to confirm its structural type and scale, and also consider the influence of the weight of various components on its movement speed, accuracy and stiffness.
(2) Planning of the wrist organization of the operating machine
The wrist tissue is generally 1-3 degrees of freedom, and it is required to be able to complete three forms of movement: reversal, deflection or swing and pitch.
When planning the wrist tissue, it is necessary to confirm its structural type and continuous scale, and pay attention to inducing movement. In order to make it compact, it is necessary to reduce its weight and volume, so as to facilitate the arrangement of the drive transmission and improve the accuracy of the wrist movement.
(3) Planning of the end actuator
According to the requirements of different work missions, first confirm its type and organizational form, and make its type and organizational form as much as possible, and make it as simple, compact and light as possible to reduce the load on the arm.
