3D Area Sensor Bin Picking - FANUC M-20iA and M-10iA Robots

Wauseon Machine developed a system where an M-20iA robot depalletizes parts out of a bin and drops them onto a table. A 3D Area Sensor then determines the random locations of the parts and allows (2) M-10iA/12S robots to pick them up and present them to welders. Finished parts are dropped into a bin.

The secondary vision camera determines if the part is flipped or unflipped. Then based on that the robot will regrip the part with the gripper oriented flipped or unflipped. Pressure is pneumatic for gripping and hydraulic for ped welder. The process requires precision for the weld nut placement relative to the part/bracket.

I enjoyed the video. I have some questions.
1. 00:09 If the part is flipped upside down, how does the gripper take the product?
2. 00:14 What is the driving principle of taking the product? Do you use hydraulic or pneumatic pressure?
