Question: I don't know if you are familiar with [KinEtre](http://research.microsoft.com/apps/video/default.aspx?id=177016), software from Microsoft, but, if you are, you know that the software only allows you to work with human-like skeletons and if you have more complex armatures, like a robot, let's say, whose wheels you want to rotate, you won't be able to in KinEtre. So, do you think I can import data from KinEtre into Blender and break it apart to create an animation from it? When I say break it apart, I mean like if I am scanning a car, I would need to separate the car's wheels, so I can rotate them separately. Is this possible?

Answer: 
If you have a really simple case where both loops are the same size and have the same number of edges, aligned on a common axis, like this:

then you can use the scale function to close the gap to zero. 
In the case of the situation shown:
Start by selecting your edge loops (ALT+Right Click on a loop edge)
Set your pivot center to Median Point![median point](https://i.stack.imgur.com/8Z042.png)
Enter `S``Z` and "0"

and pull up the Vertices menu `CTRL`+`V` and do 'remove doubles.' This will give you a single mesh with a loop at the equator of the two merged edge loops
-but I suspect you're looking for a procedure for less than optimzed conditions. Something like this:

In this case, the only constraint you really need to be sure of is that you have the same number of vertices in both loops.
Assuming you want to merge the two loops at their interpolated center:
Connect the two loops using an edge bridge

I know you really didn't want to hear, "bridge edge loops", but bear with me-you will get the results you've described
Add a loop cut (`CTRL`+`R`) to the bridge. The loop will be created at the equator of the bridge (right-click to exit) loop cut.

Next, select the loops on either end of the bridge and from the delete menu (`x` ,) select "Edge Loops":![edge loops](https://i.stack.imgur.com/S2wGx.png)
The result will be that the open edges are merged at the loop cut.

The bridge tool now has a merge toggle. You can enable this after performing the bridge.
