A robotic arm is a mechanical device that can be automated or manually controlled.
An industrial robot is a type of automated equipment, and a robotic arm is a type of industrial robot. There are other forms of industrial robots as well. Therefore, although the two terms have different meanings, they do refer to some overlapping aspects.
A robotic arm is a fixed or mobile machine, typically composed of a series of interconnected or relatively sliding parts, used to grasp or move objects. It is capable of automatic control, repeatable programming, and multiple degrees of freedom (axis). Its operation primarily involves linear motion along the X, Y, and Z axes to reach a target position.
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.
Industrial robots, as defined by ISO 8373, are automated machines that perform tasks, relying on their own power and control capabilities to achieve various functions. They can be commanded by humans or operate according to pre-programmed procedures. Modern industrial robots can also act according to principles established by artificial intelligence technology.
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.
