There is a difference between a robotic arm and a robot. Don’t be stupid and confused.

Robot arm: It is a fixed or mobile machine. Its structure is usually composed of a series of interlinked or relatively sliding parts. The working mode is mainly through linear movement along the X, Y, and Z axes to reach the target position. Realize the grasping or moving of objects, can realize automatic control, repeatable programming, and multiple degrees of freedom (axis).

The working mode is mainly through linear movement along the X, Y, and Z axes to reach the target position. Realize the grasping or moving of objects, can realize automatic control, repeatable programming, and multiple degrees of freedom (axis).

Industrial robot: According to ISO 8373, it is defined as a machine device that relies on its own power and control ability to perform work. It can accept human command, can also operate according to a pre-arranged program, and can also act according to the principles and guidelines established by artificial intelligence technology.

Similarities between the two

A mechanical arm is a mechanical device, which can be automatic or human-controlled; an industrial robot is a kind of automation equipment, and a mechanical arm is a type of industrial robot, and industrial robots also have other forms.

Although the two have different meanings, they refer to overlapping parts. So in simple terms, there are many forms of industrial robots, and the robotic arm is just one of them.

The robotic arm is the most widely used mechanical device in the field of robotics, which is widely used in the fields of industry, medicine, military, and space. Manipulators are divided into four-axis, five-axis, six-axis and multi-axis, 3D/2D robots, independent manipulators, hydraulic manipulators, etc. Although there are many types, they have one thing in common is that they can receive instructions and accurately locate three-dimensional (or two-dimensional) ) Point in space to perform operations.

Usually in the industrial field, robots and mechanical arms use a fixed base without a walking mechanism. It is often thought that: industrial robot = robotic arm = robotic arm = robotic arm.

The difference between the two

The difference between a robot and a robotic arm is that the robot can not only receive instructions from humans, it can also perform tasks in accordance with human pre-programmed programs, and it can also act according to the principles specified by artificial intelligence. In the future, robots will assist or replace more human tasks, especially repetitive tasks and dangerous tasks.

The definitions of robots in European and American countries and Japan are different:

European and American countries believe that robots should be controlled by a computer, making them a multi-functional automatic machine through programming; Japan believes that robots are advanced automatic machines, so the robotic arm is included in the definition of robots.

European and American countries believe that manipulators with 6 axes and above can be called robots, and those with 5 axes and below can only be called robotic arms; Japan defines 3-axis manipulators as robots.
