  The selection and placement of objects is a very difficult task for past robotic systems because there is no good way to locate them. However, with the three-dimensional visual innovation and development, positioning and picking movements become more and more easy.
  The advent of 3D vision has driven the rapid innovation of industrial robots and broadened their application prospects. New vision technologies provide the robotics system with the flexibility to enable them to do functions they have never seen before.
  The industrial robot itself is an incredible innovation in the manufacturing industry, but the "blind" version of the robot has its limitations. So what is the difference between 3D vision-guided robots and traditional robots?
  Robots are largely used to replace dull, repetitive work, which has finally liberated the low-end workforce. However, because of their lack of visual perception, which limits their ability to accomplish more high-end tasks, traditional robots must be programmed to accomplish a single task without the ability to cope with new changes and must be reprogrammed as the mission changes.
  Flexibility is a key driver of robot ROI, and 3D vision capabilities will allow robots to perform multiple tasks without reprogramming, with predictable unforeseen emergencies in the work environment. In addition, 3D vision allows the robot to recognize the object in front of it to some extent and respond accordingly. All of these enhance the robot"s flexibility for faster and better ROI.
  At present, there are many methods for industrial robots application of 3D vision technology. One of the most prominent applications is picking and placing, which is very difficult for traditional robots. Blind robots can only pick up objects from a predetermined position. Two-dimensional cameras The system can not pick out part of the scene.
  The 3D vision achieved by laser triangulation is one of the most commonly used methods for robot vision in pick-and-place applications. In essence, a computer-aided design (CAD) model is taught to a robot so that it can recognize a portion of the space and its direction. The laser is used by the robot to determine its own spatial position in the X, Y, and Z axes. Once the robot knows where it is and where it is, it can pick up the part and place it.
  Although this may seem a simple task, it is a revolution in the industrial field. It saves end-users time and money. With a brief description of the CAD model, the robot can perform a variety of tasks.
  Whether it"s laser triangulation or a different approach, 3D vision is the driving force behind innovation. Robot selection and use in the past is very difficult, but now it will be a normal operation.
