Strategies for Obtaining Containers from the Center?

[totesmagotes]

Just wondering if there were any strategies bouncing around out there already about how to get the recycling containers that are in the middle of the playing field surrounded by totes. Getting these quickly could help just to stop the other alliance from scoring with them even if your alliance cannot. Some ideas our team has had was using a (safe) grappling hook that the robot would launch into the container, but that would require high accuracy and a way to detach the hook easily? So, any ideas??
