Vision Systems for Yaskawa Motoman Robots
Vision systems have become one of the most common forms of robotic technology. Many industrial robot users are opting to integrate their robots with vision systems for additional intelligence. Vision guided articulated robots are able to gather visual data for complete optimization of their operation. Vision systems allow robots to automate more complex tasks while enhancing their performance. They add value through improving product quality, reducing costs, and increasing productivity.
Many robotic manufacturers have realized the value of offering their customers vision system options. Yaskawa Motoman is one of the top robotic manufacturers in the world due to their innovative robots and technology options. One of the technology options they offer is their own robotic vision system called MotoSight. Yaskawa Motoman has partnered up with Cognex cameras to create a vision system specifically designed for their robots. MotoSight allows for easy integration with Yaskawa Motoman robots and those with Yaskawa Motoman robots can avoid having to search for a compatible third party vision system. MotoSight allows robots to handle unpredictable scenarios and environments. Integrating the Yaskawa MH24 with MotoSight gives it the capability to identify different parts and different locations. The MH24 is able to identify a weld location with MotoSight. While the Yaksawa MH12 can use MotoSight to inspect its work post assembly. MotoSight allows robots to process information dynamically instead of having to halt operation to program changes.
Yaskawa Motoman’s MotoSight comes with all hardware, software, cameras, and lighting needed for vision guided robots. The vision system is available as either a 2D or 3D solution.
- • MotoSight 2D - MotoSight 2D features a two-dimensional camera that is best for general guidance, automated inspection, part recognition, and high-speed picking. MotoSight 2D provides visual data for X, Y, and angle coordinates. A 2D system is best for structured applications, meaning objects remain on the same plane and the distance from the object and camera are fixed. For instance, the Motoman MH6 can be integrated with a 2D MotoSight system for part picking when parts are organized in a pattern. The 2D camera provides general guidance to the MH6 since all objects remain on a constant plane.
- • MotoSight 3D - MotoSight 3D uses a three-dimensional camera that is best for more complex or unpredictable applications. These involve any process in which parts or locations are completely randomized. There is no structure or pattern so the six axis robot will need more detailed visual information which can be provided by a 3D camera. MotoSight 3D can provide visual data for the X, Y, and Z coordinates as well as angle and tilt imagery. The distance between the camera and objects does not have to be constant. Applications that involve parts overlapping, randomized in a bin, or a mixture of different part types will require 3D MotoSight. Integrating the Yaskawa MH180 with MotoSight 3D will give it the ability to identify specific parts from a bin containing a mixture of different objects. Parts are accurately identified in one step with single-step recognition and 3D CAD matching. MotoSight 3D also features collision checking to prevent the EOAT from colliding with peripherals.
