A robotic arm is a fixed or mobile machine, typically composed of a series of interconnected or sliding parts. It works by moving linearly along the X, Y, and Z axes to reach a target position, thus grasping or moving objects. It can be automatically controlled, programmable, and has multiple degrees of freedom (axis). A robotic arm can be automatic or manually controlled; it is an electromechanical system that simulates the movements of a human hand and arm. It is merely an extension of the human hand and arm, lacking autonomous capabilities, and is attached to the host device. Its movements are simple, with fixed, repetitive operations, and a fixed positioning point. Robotic arms are widely used in the field of robotics, with applications in industry, medicine, and even the military. Robotic arms are categorized 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 share the common feature of receiving commands and positioning themselves at a point in three-dimensional (or two-dimensional) space to perform operations.
Robots: Here, we are often referring to industrial robots. An industrial robot is an automated device that comes in many forms, with a robotic arm being just one type. It can be programmed, but it typically needs to be assembled with an end effector (robotic arm) to form a complete machine; an industrial robot is a whole, with the robotic arm being only a small part. Industrial robots are machines that perform tasks using their own power and control capabilities. They can be commanded by humans, operate according to pre-programmed procedures, or act according to principles established by artificial intelligence technology. Industrial robots generally have independent controllers, drive systems, and operating interfaces, allowing for manual and automatic operation and programming. Therefore, it is a complete, independently operating device that can achieve its required functions through its own control system. This equipment has independent mechanical mechanisms and control systems, enabling autonomous, complex movements, multiple degrees of freedom in operation, variable operating programs, and arbitrary positioning automated manipulators.
Imagine a person as an industrial robot, and a person's hand as a robotic arm. In industrial applications, robots and robotic arms typically use a fixed base and do not have a locomotion mechanism.
A robotic arm performs simple actions, such as simply grasping and placing objects, while a robot is one that performs complex tasks.
A robotic arm doesn't listen to simple commands, but a robot can execute simple commands; this is a term that implies intelligence.
Robots possess excellent programmability and versatility, enabling them to meet the requirements of diverse industrial products and small-batch production, thus expanding their application areas. In industrial production, industrial robots such as arc welding robots, spot welding robots, assembly robots, painting robots, and handling robots are already widely used.
