Suction gripper

[ghostman126]

Hey everyone, I am new to this forum and I do not participate in FRC. However, I do participate in a very similar competition, JSDC which is organized by AMD. Anyway this year, the competition requires us to pick up of cones like these http://www.oronosports.com/catalog/i...isc%20copy.jpg and place them in rods which are placed vertically and horizontally. My team is trying to use a suction gripper to solve this but we are very unsure of what the system should be like/what parts to use. The good thing is that we have no restrictions on what parts we can use. Has any of you had experience building a suction gripper to pick up similar objects before? If you have any ideas/experiences, I would love to find out more.
