A robotic arm is a mechanical device that can be automatic or human-controlled; Industrial robot is a kind of automation equipment, mechanical arm is a kind of industrial robot, and industrial robots also have other forms. Therefore, although the meanings of the two are different, there is some overlap in the content of the references.
So to put it simply, there are many forms of industrial robots, and the robotic arm is just one of them.
Industrial robotic arms
An industrial robotic arm is "a stationary or mobile machine that is constructed, usually consisting of a series of interconnected or relatively sliding parts that grip or move an object, capable of automatic control, repeatable programming, and multiple degrees of freedom (axes)." Its working mode is mainly to reach the target position by doing linear motion along the X, Y, and Z axes. ”
Industrial robots
According to the definition of ISO 8373, an industrial robot is a machine device that performs work automatically, and is a machine that relies on its own power and control ability to achieve various functions. It can be commanded by humans or run according to pre-programmed programs, and modern industrial robots can also act according to the principles and programs set by artificial intelligence technology.
The difference between a robot and a robotic arm
· The robotic arm is the most widely used mechanical device in the field of robotics, which is widely used in industry, medical and even military and space fields. The robotic arm is divided into four-axis, five-axis, six-axis and multi-axis, 3D/2D robots, independent robotic arms, hydraulic robotic arms, etc., although there are many types, but they have one thing in common is that they can receive instructions and accurately locate the points in three-dimensional (or two-dimensional) space for operation.
· Robots differ from robotic arms in that robots can not only receive instructions from humans, but also perform operations according to human pre-programmed programs, and act according to the principles specified by artificial intelligence. In the future, robots will assist or replace more human work, especially some repetitive work, dangerous work, etc.
The difference between a robot and a robotic arm in terms of application range:
· The robotic arm is widely used in the industry, and the main technology it contains is drive and control, and the robotic arm is generally a series structure.
· Robots are mainly divided into series structure and parallel structure: parallel robot (PM) is mostly used in occasions that require high stiffness, high precision, high speed, and no large space, and is specifically used in sorting, handling, simulated motion, parallel machine tools, metal cutting processing, robot joints, spacecraft interfaces, etc.; The tandem robot and the parallel robot constitute a complementary relationship in the application, and the working space of the tandem robot is large, which can avoid the coupling effect between the drive shafts. However, each axis of the mechanism needs to be controlled independently, and encoders and sensors are needed to improve the accuracy of the movement.

What are the six subsystems of Universal Robots – Industrial Robot Systems?
1. Mechanical structure system
From the perspective of mechanical structure, industrial robots are generally divided into tandem robots and parallel robots. The characteristic of a tandem robot is that the movement of one axis will change the coordinate origin of another axis, while the movement of one axis of a parallel robot will not change the coordinate origin of another axis.
