This is the mat and missions for First Lego League's Ocean Odyssey. It is complete and comes with the building instructions CD. I am the robotics coach for our local middle school and have some old FLL challenges that I need to get out of my guest room. This challenge has an ocean theme and is great to use with either the RCX or NXT. (Will enclose mission objectives and scoring sheet.) This kit was used for practice and has the dual lock on the mat and pieces. Due to the size of the research vessel, the pipeline, and the sling, these have been slightly disassembled in order to fit in the box. (I have color coded the parts to show w they belong.) Also, the flags have been removed from their holders to reduce the chance of breaking. Item ships in two packages. Mat is in 4x4x47 inch box to prevent creasing. Comes from smoke-free home. Questions welcome.
