In the past Davis Creek has made some large systems engineering projects.
We have motorized simple machine sets.
Also there is a new CAD on LEGO.com ( LEGO Digital Designer) that has small projects.
Together we are going to make a 16 by 16 project
that can be combined with three or more others to be a systems engineering
projects.
The design will be like the pink squares.
The green square from the simple motorized sets is the right size.
The path to move a little car will be like a teeter totter.
