Articulated robots, also known as articulated arm robots or articulated robotic arms, are one of the most common forms of industrial robots in the industrial field today. It is suitable for mechanical automation operations in many industrial fields, such as automatic assembly, painting, handling, welding, etc.
The so-called axis of industrial robots can be explained by the professional term "degrees of freedom". It is reasonable to assume that as the number of axes of the robot increases, the robot has more flexibility. Four-axis SCARA robot (hereinafter referred to as four-axis robot) and six-axis articulated robot (hereinafter referred to as six-axis robot), where the four-axis robot is specially designed for high-speed pick-and-place operations, and the six-axis robot provides higher flexibility in production movement.
The axis is closely related to the Kadir coordinate system. A three-axis robot, also known as a Cartesian or Cartesian robot, allows the robot to move in the direction of the three axes; The six axes in the six-axis robot are the X Y Z axis in the Cartesian coordinate system, and the U V W axis that rotates around the X Y Z axis.
Four-axis robot
The four axes are designed for high-speed pick-and-place operations, and the six axes with two axes provide greater flexibility. Among the small assembly manipulators, the "four-axis manipulator" refers to the "selective assembly joint robotic arm", that is, the arm part of the four-axis manipulator can move freely in a geometric plane. The first two joints of the quadcopial robotic arm can rotate freely left and right in the horizontal plane, and the third joint consists of a metal rod called a quill and a gripper. This metal rod can be moved up and down in the vertical plane or rotated around its vertical axis, but not tilted.
This unique design gives four-axis manipulators a high degree of rigidity, allowing them to perform high-speed and repetitive work. In packaging applications, four-axis manipulators excel at high-speed pick-and-place and other material handling tasks.
Six-axis robot
Six-axis robots have two more joints than four-axis robots, so they have more "freedom of movement". The first joint of the six-axis robot can rotate freely in the horizontal plane like a four-axis robot, and the last two joints can move in the vertical plane. In addition, the six-axis robot has one "arm" and two "wrist" joints, giving it human-like arm and wrist capabilities.
The six-axis robot's more joints mean that they can pick up parts in any orientation on the horizontal plane and place them in the packaged product at a special angle. Perform many operations that can only be done by skilled workers. And it can save labor costs, which is a good choice for newly established enterprises.
Four-axis and six-axis robots can be collectively referred to as "automation", automation technology can not only liberate people from heavy physical labor, part of mental labor and harsh and dangerous working environments, but also expand human organ functions, greatly improve labor productivity, and enhance human ability to understand the world and transform the world.
Robotic Automated Packaging Application Guide The integration and application of robotics technology in packaging production lines is not as complex, dangerous and expensive as some people think, but it is very simple and safe, and it may also gain economic advantages.

Universal Robots – a classification of tactile sensors for industrial robots
1. Optical tactile sensor
There are two types of optical tactile sensors: inside and outside. In this type, the intensity of the light is adjusted by moving the obstacle to the light path. It has the advantage of being immune to electromagnetic interference and has a high resolution. Low wiring is required and the electronics can be kept away from the sensor.
