Tote Grapping Strategy

[16guevaran]

I have a concept for grabbing totes and bins and I want to hear what everyone else has to say about. If you have any comments, questions, ideas, or any other advice please comment. Any advice will be appreciated.
My idea is to use a piston connected to a motor via a chain and some suction cups with tubes connected to the piston. When the suction cups are pressed up against the side of the tote or bin, you turn the motor on, so it pulls the chain in, making it pull the piston along with it creating a vacuum. Since the other end of the piston is connected to a tube which leads to the suction cup, the created vacuum will pull on the side of the tote or bin holding it in place so that it can be picked up and moved around. There will be two of these vacuum suction cups on either side of the tote/bin so that the tote/bin will be stable when picked up, and will not fall off. This can make stacking totes easier because there is nothing underneath of the crate when the robot grabs it, so the robot can place the tote directly on top of another, making it less likely that totes on top will fall off.
