The frame is assembled, with all the parts on hand it took about 45 minutes.

Now, trueing it up will likely take much longer...

The google sketchup drawing below shows the assembly with the 4 "extra" bars installed at the bottom of the machine, this has been changed in the actual machine to the top of the frame.

The reasoning is thus: they are to enclose the power, data, and logic housed in the machine i.e. the on-board controller (PLC probably), power bus, power connectors, data bus and data interface.

If the cube is applied to a "wet" process where substances can spill, and all that gadgetry is at the bottom....

So... I put all the power, data etc at the top where this is less relevant. (assuming we don't operate in a zero G enviroment -heh ;-) )

Also in the current design a pallet transporter is incorporated at the bottom of the cube but this is not shown yet as I have not worked out how to integrate the LIM (Linear Induction Motor)controls as a 4th axis, or weather the pallet will "park" and lockdown in some types of cells.
