definition
Robotic arm: A fixed or mobile machine, which is usually composed of a series of interconnected or relatively sliding parts. It works by moving linearly along the X, Y, and Z axes to reach the target position, thereby grasping or moving objects. It can achieve automatic control, repeatable programming, and multiple degrees of freedom (axis).
Industrial robots: As defined by ISO 8373, they are machine devices that perform work by their own power and control capabilities. They can be commanded by humans, operate according to pre-programmed procedures, or act according to principles and guidelines established by artificial intelligence technology.
Similarities between the two
A robotic arm is a mechanical device that can be automated or manually controlled; an industrial robot is an automated device, and a robotic arm is a type of industrial robot, which also come in other forms. Although the two terms have different meanings, they refer to some overlapping aspects. Therefore, simply put, there are many forms of industrial robots, and a robotic arm is just one of them.
Robotic arms are the most widely used mechanical devices in the field of robotics, with applications in industry, medicine, and even military and aerospace. Robotic arms are classified into four-axis, five-axis, six-axis, and multi-axis types, 3D/2D robots, independent robotic arms, hydraulic robotic arms, etc. Although there are many types, they all have one thing in common: they can receive commands and accurately position themselves at points in three-dimensional (or two-dimensional) space to perform tasks.
In the industrial field, robots and robotic arms typically use fixed bases and do not have walking mechanisms. It is often assumed that industrial robots = robotic arms = robotic hands = robotic arms.
The difference between the two
Unlike robotic arms, robots can receive human instructions, perform tasks according to pre-programmed instructions, and act according to principles defined by artificial intelligence. In the future, robots will increasingly assist or replace human workers, especially in repetitive and hazardous tasks.
The definitions of robots differ between Western countries and Japan:
Western countries believe that robots should be computer-controlled, and that programming them into multifunctional automated machines; Japan, on the other hand, considers robots to be advanced automated machines, so robotic arms are included in the definition of robots.
In Europe and America, robotic arms with 6 or more axes are considered robots, while those with 5 or fewer axes are simply called robotic arms; Japan, on the other hand, defines a 3-axis robotic arm as a robot.
