Deep Foundation Laser Scanner

Today I'm writing the code and testing the integration of the Sharp sensor with the Stepper motor. Apparently, that's ok. I need to do more testing. 

The conection it's simple and I don't want to keep a lot of wires now.

I need to verify the basic assembly.

With this simple assembly, I get the first turn of points. And I inserted into a CAD program.

I'm devoting my time thinking about the concept of Taipei and how I'm going to solve the pendulum in my project.

So, when I tell to anyone about m project, they ask me about the pendulum and how I plan to solve it. Really? At fisrt I was not worried about this problem, I calculated all centers of gravity(CG), and it's ok.  But now, when I think about the vibration and others interferences.... yes, I will solve this.

I begin with the idea of a pendulum and his lenght "L", and I considered to use a dual pendulum to make a opposite force. But I'm don't convinced that's will run well.

With this problem, I remembered of the Taipei 101 tower and his anti seismic system.

I have the same problem but upside down.

Now, I have a concept to how to do this.

Ok, it's a important point: The price.

I'm fix the cost on US$200.00 today, the most heaviest participation on project is the arduino starter kit. I found it from a man that bought this kit but can't spent time to do anything arround the arduino. And the other items, I bought as new. 

That's the basic internal flow work.

It describes how I'm planning that it runs.

that's the first version of the flow work. I think that is not the last version of the flow work.

Today I'm modeling the basic 3D and making some tests with the Sharp sensor. My biggest doubt was about the deflection of the IR beam and now, its ok. It's a relief.

Now I'm working on the system that will make on Z axis movimentation.

Maybe I use a fixed point of the cable on level 0m and a reel to variate the elevation. To get this data, I can use a servo motor and convert his turns to Z axis distance.

Yeap, it's on paper! 

Here I show the main parts about the internal work flow.

The original idea was using a Kinnect sensor(Xbox 360) to make a point cloud but it's demmand a hard processing time. So, to do the simple, I changed this to a own laser scanner. 
How it's run:
The IR(Sharp sensor) beam will be reflected on a rotating(stepper motor) dielectric mirror. The result is a meassure X,Y on 360º.

Therefore, I have to solve the problema in Z axis. Maybe I use a servo motor or other stepper motor to control up and down on the hole.

It's a simple definition  about how I planning the steps to the operation on the data extraction. It's the main task: plan "HOW" and "WHAT" I am trying to do. The result is shown on the image below:
