Robotic Vision

Vision systems free robots from the narrow restrictions of time and space, providing a host of advantages in a wide variety of manufacturing applications. These advantages enable more widespread use of robots by guiding their actions to closely fit ever-changing and more-demanding production requirements.
By adding a vision system to the robotic system, the flexibility of robotic automation is increased. The robot can find objects in the work area, regardless of part sizes, shapes and changes in position, without the need for complex and expensive tools. It’s even possible to track and pick parts in motion on a conveyor.
Robotic vision systems typically consist of one or more cameras, application-specific lighting, special software, one or more robots.
How Does Robotic Vision Work?
For example, consider a stationary mounted camera, a planar work surface, and an object that must be gripped by the robot.The object may be lying flat on that surface and mixed amongst other items.The main steps carried out during each cycle include:
  • A suitable image is acquired
  • The object of interest is detected in the image.
  • The position and orientation of the object are determined.
  • This position is translated into the robot’s coordinate system.
  • The information is sent to the robot.
  • Using this information, the robot moves to the appropriate position and orientation to grasp the object in a predictable way.
Types of vision systems :
  • 1D Vision Systems
  • 2D Vision Systems
  • Line Scan or Area Scans
  • 3D Vision Systems
Robotic Applications Using Robotic Vision:
  • Pick and Place
  • Assembly
  • Quality Inspection
  • Packaging and Palletizing
  • Screw Driving
  • Labeling
  • Gluing, Dispensing and Welding
  • Polishing
  • Injection Molding
Benefits of Robotic Vision :
  • A robot can perform multiple tasks
  • The need for expensive fixtures is eliminated
  • Switching between products and batch runs is software controlled and very fast, with no mechanical adjustments.
  • Downtime is reduced
  • Speeds production and increases throughput
  • The need for manual programming of the robot is reduced
  • High machinery efficiency, reliability, and flexibility
  • Possibility to integrate a majority of secondary operations such as deburring, washing, measuring and so on.
  • Reduces manual work
