A vacuum pump is very efficient for fast and reliable pick and place, and allows you to pick some objects that a normal gripper can't pick. Ex : take out the cover of a flat box, move soda cans from the top, pick and place large objects with a flat surface.
Most vacuum pumps are making so much noise, you just can't stand and work near the robot, it is too disturbing. The pump we've developed is different : it's operating silently, with the same efficiency as a vacuum pump, for the same price. A servomotor actuates a syringe which pumps the air out.
We've also made a custom Niryo box for this vacuum pump !
