Manipulator arm: it is a fixed or mobile machine, and its structure is usually composed of a series of interconnected or relatively sliding parts. Its working mode is mainly to achieve the target position by doing linear movement along the X, Y, Z axis, so as to achieve object grasping or moving. It can achieve automatic control, repeatable programming, and multiple degrees of freedom (axis).
Industrial robot: it is defined as a machine device that performs work by its own power and control ability according to ISO 8373. It can accept human command, run according to pre arranged programs, and act according to the principles and programs formulated by artificial intelligence technology.
Similarities of manipulator arm and industrial robot:
The manipulator arm is a kind of mechanical device, which can be automatic or manually controlled; Industrial robot is a kind of automatic equipment, manipulator arm is a kind of industrial robot, and industrial robot also has other forms. Although they have different meanings, there are some overlapping parts of the reference. So simply speaking, there are many forms of industrial robots, and the manipulator arm is just one of them.
Manipulator arm is one of the most widely used mechanical devices in the robot field, which is widely used in industry, medical, military and space fields. The manipulator arm is divided into four axis five axis six axis multi axis, 3D/2D robot, independent manipulator arm, hydraulic manipulator arm, etc. Although there are many kinds, they have one thing in common, that is, they can receive commands and accurately locate points in three-dimensional (or two-dimensional) space for operation.
Generally, in the industrial field, robots and manipulator arms use fixed bases without walking mechanisms. It is often believed that: industrial robots=robots=manipulators=manipulator arms.
The difference between them:
The difference between robot and manipulator arm is that robot can not only receive human instructions, but also perform operations according to human pre programmed programs, and 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.
European and American countries and Japan have different definitions of robots:
European and American countries believe that robots should be controlled by computers, and make robots into multi-functional automatic machines through programming; Japan believes that robots are advanced robots, so manipulator arms are included in the definition of robots.
European and American countries believe that a manipulator arm with 6 or more axes can be called a robot, while a manipulator arm with 5 or less axes can only be called a manipulator arm; Japan defines the 3-axis manipulator arm as a robot.
