"UFO" Miner Minecraft Construction

This build is the UFO Miner.  The UFO moves through the Minecraft world in one of two ways:

Either you step or jump on a pressure plate, or you flip one of the levers to go up or down.  

As the UFO moves in any direction, it will destroy blocks in its path, so you can collect them.

For this build, you will need 17 Command Blocks, labelled on the picture.

Notice that the UFO has a “South Facing Side”, this is not trivial— the orientation is crucial to the design-- as the commands in each command block correspond to movement in a specific direction/dimension, getting the incorrect command in the incorrect block will wreck your UFO.  (Not pictured is the UB Bottom command block, it is directly under the UB Block)

How it works:

First, the blocks in the direction you are moving towards are broken.

Second, the blocks of the UFO are moved, using the clone command.

Third, the player is teleported a couple of spaces.  

Note:  The second step makes the operation a little jumpy, as the UFO moves without the player. 

But the third step in the process makes the operation very jumpy, but it keeps the player from falling *through* the UFO during a volatile moment (and potentially to your death or into lava or something).  

Here are the commands for each block:

PE command block= /fill ~2 ~ ~-3 ~2 ~2 ~3 air destroy

PW command block= /fill ~-2 ~ ~-3 ~-2 ~2 ~3 air destroy

PN command block= /fill ~-3 ~ ~-2 ~3 ~2 ~-2 air destroy

PS command block= /fill ~-3 ~ ~2 ~3 ~2 ~2 air destroy

CN command block= /clone ~-2 ~ ~-1 ~4 ~2 ~5 ~-2 ~ ~-2 replace move

CS command block= /clone ~-4 ~ ~-5 ~2 ~2 ~1 ~-4 ~ ~-4 replace move

CE command block= /clone ~-5 ~ ~-2 ~1 ~2 ~4 ~-4 ~ ~-2 replace move

CW command block= /clone ~-1 ~ ~-4 ~5 ~2 ~2 ~-2 ~ ~-4 replace move

DB Command Block TOP= /fill ~-6 ~-2 ~-6 ~ ~-2 ~ air destroy

DB Command Block BOTTOM= /clone ~-6 ~ ~-6 ~ ~2 ~ ~-6 ~-1 ~-6 replace move

UB Command Block TOP= /fill ~ ~2 ~ ~6 ~2 ~6 air destroy

UB Command Block BOTTOM= /clone ~ ~ ~ ~6 ~2 ~6 ~  ~1 ~  replace move

TU Command Block= /teleport @p ~ ~2 ~1

TN command block= /teleport @p ~-1 ~3 ~2

TE command block= /teleport @p ~-2 ~2 ~-1

TS command block= /teleport @p ~1 ~2 ~-2

TW command block= /teleport @p ~2 ~2 ~1

This is a prototype, very ugly and no-frills, and can be made much larger and more ornate.
