Direct interfacing of smart 3D vision system with robots
Summary
2D-driven systems can only locate parts on a flat plane relative to the robot. Robotic systems equipped with 3D vision, on the other hand, can identify parts randomly posed in three dimensions (i.e., X-Y-Z), and accurately discover each part’s 3D orientation. Gocator snapshot sensors combine fringe projection using blue-LED structured light with a rich array of built-in 3D measurement tools and decision-making logic to scan and inspect any part feature with stop/go motion at speeds up to 6 kHz. The blue LED projects one or more high-contrast light patterns onto the object to allow full-field 3D point cloud acquisition by the stereo cameras, providing excellent ambient light immunity, even in challenging conditions. The combination of these metrology-grade snapshot sensors with UR devices gives a complete robotic solution that delivers high-performance 3D results in robot vision-guidance, quality control inspection, and automated assembly with smart pick and place.
