So the robot arrived, if you don't mind having no instructions whatsoever and nothing lining up then this is the kit for you. It took a few tried before I found holes that would work for two layers but they are not symmetrical.  The package was for two turtle bots ,but the package was ripped open and much of the hardware missing. There is no labeling on these either.  I may rethink using this as a test platform and 3D print something to go on top of the rover 5 4x4 with encoders instead. We will see and I will update you.
