Industrial robot is a kind of automation equipment, mechanical arm is a kind of industrial robot, industrial robots also have other forms, although the meaning of the two is different, but the content of the reference has overlapping parts. So to put it simply, there are many forms of industrial robots, and the robotic arm is just one of them.
What is a robotic arm?
The robotic arm is a kind of mechanical equipment, which can be automatically or artificially controlled, and refers to a messy system with high precision, multiple inputs and multiple outputs, high nonlinearity, and strong coupling; Due to its common operational flexibility, it has been widely used in industrial installations, safety and explosion protection, etc.
The robotic arm is a chaotic system, with uncertainties such as parameter perturbation, external interference, and unmodeled dynamics. Therefore, there is also uncertainty in the modeling model of the robotic arm, and for different missions, it is necessary to plan the motion orbit of the joint space of the robotic arm, so as to cascade to form the terminal pose.
What is an Industrial Robot?
Industrial robot is a multi-joint manipulator or multi-degree of freedom machine and equipment for the industrial category, which can automatically perform operations and is a machine that relies on its own power and control ability to complete various functions. It can withstand human command, it can operate according to pre-programmed procedures, and modern industrial robots can also act according to guidelines drawn up by artificial intelligence skills.
The industrial robot is composed of three basic parts: the main body, the drive system and the control system. The main body is the frame and actuator, including the arm, wrist and hand, and some robots also have a walking mechanism. Most industrial robots have 3-6 degrees of freedom of movement, of which the wrist usually has 1-3 degrees of freedom of movement; The drive system comprises a power equipment and a transmission mechanism to make the actuator act accordingly; The control system sends command signals to the drive system and actuator according to the input program, and controls them.
The difference between a robotic arm and an industrial robot
The robotic arm is one of the most widely used mechanical devices in the field of robots, and is widely used in industrial, medical, and even military and space fields. The robotic arm is divided into four-axis, five-axis, six-axis and multi-axis, 3D/2D robots, independent robotic arms, hydraulic robotic arms, etc., although there are many varieties, but they have one thing in common is that they can receive instructions and accurately locate the points in three-dimensional (or two-dimensional) space for operation.
Robots differ from robotic arms in that they can not only receive instructions from humans, but also perform tasks according to pre-programmed human programs, and can also act according to guidelines specified by artificial intelligence. In the future, robots will help or replace human operations more, especially some repetitive operations, dangerous operations, etc.
Differences between robotic arms and industrial robots in the scope of use:
Robotic arms are widely used in the industrial world, and the main skills they include are actuation and control, and the robotic arms are generally in tandem structure.
Robots are mainly divided into series structure and parallel structure: parallel robot (PM) is mostly used in occasions that require high stiffness, high precision, high speed, and no large space, and is specifically used in sorting, handling, imitation motion, parallel machine tools, metal cutting processing, robot joints, spacecraft interfaces, etc.; The tandem robot and the parallel robot constitute a complementary relationship in use, and the working space of the tandem robot is large, which can avoid the coupling effect between the drive shafts. However, each axis of the mechanism needs to be operated independently, and encoders and sensors are required to improve the accuracy of movement.

Obstacle avoidance control of the manipulator – KUKA robots
The kinematic redundancy of freedom of the manipulator means that the manipulator has more degrees of freedom than is required at the end of the manipulator. Kinematic manipulators with redundant degrees of freedom have better functions than manipulators with non-redundant degrees of freedom. For example, a manipulator with non-redundant degrees of freedom has obstacles in the external environment.
