“An industrial robot is a kind of automation equipment, a robotic arm is a kind of industrial robot, and industrial robots also have other forms. Although the meanings of the two are different, the content they refer to overlaps. So simply put, there are many forms of industrial robots, and the robotic arm is just one of them.

What is a robotic arm?
The manipulator is a mechanical device, which can be either automatic or human-controlled. It refers to a complex system with high precision, multiple inputs and multiple outputs, high nonlinearity and strong coupling. Because of its unique operational flexibility, it has been widely used in the industry. It is widely used in the fields of assembly, safety and explosion-proof.
The robotic arm is a complex system with uncertainties such as parameter perturbation, external disturbance and unmodeled dynamics. Therefore, there is also uncertainty in the modeling model of the manipulator. For different tasks, it is necessary to plan the motion trajectory of the manipulator joint space, so as to cascade to form the end pose.
What is an industrial robot?
An industrial robot is a multi-joint manipulator or a multi-degree-of-freedom machine device for the industrial field. It can perform work automatically and is a machine that realizes various functions by its own power and control capabilities. It can be commanded by humans or run according to pre-arranged programs. Modern industrial robots can also act according to the principles and programs formulated by artificial intelligence technology.
The industrial robot consists of three basic parts: the main body, the drive system and the control system. The main body is the base and the actuator, including the arm, the wrist and the hand, and some robots also have a walking mechanism. Most industrial robots have 3 to 6 degrees of freedom of movement, of which the wrist usually has 1 to 3 degrees of freedom of movement; the drive system includes a power device and a transmission mechanism to make the actuator produce corresponding actions; the control system is based on the input The program sends out command signals to the drive system and the actuator, and controls it.
The difference between robotic arms and industrial robots
The robotic arm is the most widely used mechanical device in the field of robotics, widely used in industrial, medical and even military and space fields. Robotic arms are divided into four-axis, five-axis, six-axis, multi-axis, 3D/2D robots, independent robotic arms, hydraulic robotic arms, etc. Although there are many types, they have one thing in common is that they can receive instructions and accurately locate to three-dimensional (or two-dimensional) ) points in space to do the job.
The difference between robots and robotic arms is that robots can not only receive instructions from humans, but also perform tasks according to pre-programmed programs by humans, and can also act according to the principles specified by artificial intelligence. In the future, robots will more assist or replace human work, especially some repetitive work, dangerous work, etc.
The difference between robotic arms and industrial robots in the scope of application:
Manipulators are widely used in the industry, and the main technologies included are drive and control. Manipulators are generally connected in series.
Robots are mainly divided into series structure and parallel structure: parallel robots (PM) are mostly used in occasions requiring high stiffness, high precision, high speed, and no large space, and are specifically used in sorting, handling, simulated motion, parallel machine tools, and metal cutting. , robot joints, spacecraft interfaces, etc.; the series robot and the parallel robot form a complementary relationship in application, and the series robot has a large working space, which can avoid the coupling effect between the drive shafts. However, each axis of the mechanism needs to be independently controlled, and encoders and sensors are required to improve the motion accuracy.
