FEATURES
3D Vision Bolsters Robotic Bin Picking Feb 2, 2021 — For robots, unstructured bin picking has traditionally been challenging, if not effectively impossible. Part of the reason is mechanical, since getting a robotic arm into a bin and securing its grip on a part to pick can be difficult. Another problem, however, is the time needed for standard 2D vision to locate a part and position the robot to make a successful pick. Now the advent of less expensive and higher-performing 3D-vision technology makes random bin picking much more practical. This is...
