Deep Foundation Laser Scanner

Yes! That's a good pic. But i have some problems on the voltage to the robot.

I used 12v but I make a mistake on the wiring. So, I didn't make the test.

In the next week I will try make a new test.

Hi!

A few days ago I started the assembly and now I'm close to get this project done and use it in a real situation

Hi!

This update is about the fabrication of the robot's parts.

So, that's all.

Today I finished the new design of the prototype.

I revised the design to simplify the fabrication. The fabrication is scheduled to this week.

That's a lesson learned about the first sensor(sharp). I need to test the application of the sensor and verify if it works.

To do this, I built a paper box with known dimensions and placed the sensor on the center of the box.

That's not beautiful but runs well.

I built a mirror support and rotated the mirror around the axis sensor. And now it's fine. 360° covered by the sensor.

Hi!

In the last 2 months, I did some updates in the project. But, I'm little busy with the work and graduation so, I using the leftover time to sleep and work on this project.

Therefore, I will try update this page in the next days.

About the VL53L0X:

That's a cool TOF sensor and it runs like I imagined.

For two weeks I have been waiting for delivery of the new sensor.

But, in brazil, we have a big strike of the truck drivers at now. And any delivery need more time that foreseen.

So, I can't done my project on the time that I have planned.

I don't have any progress to show now(sorry) but, this it's a part of the project R&D.

I don't know exactly how it's works... 

When I did the first test with the Sharp sensor on a mirror, I don't know, or I can't remenber if I did all the tests that could be possible. Or if I did one test and it worked well and I jumped the other tests.  But now, I bought a lot of mirrors and neither of then works well.

I bought a dieletric mirros and normal mirrors.

The cause:

The Sharp sensor works by a triangulation of the emitter and a scale on the reciever. When I use a rotating mirror, these results can't be registered on the scale.

The solution:

I will change the Sharp sensor to the gy-530-vl53l0x

I will purchase this sensor and make a lot of tests.

Today I'm simulating the operation ( I keep on my mind ideas to solving the Z and pendulum problem).

I'm considering an turn for a 50cm in -Z axis.

... And, I get the points! \o/

... And created the mesh

With this results, I finished the first tests and solve the main concern.

When I begined to imagine the application for the scanner (in the commercial point of view), I have the idea to provide an as-built about the excavation to a BIM software. It's looking good, because this show an professional application to the project. Is a simple process:

Before a start of the scan, the GPS sensor will get the coordinates and archieve this information to input on BIM. Therefore, making the scan unique.

In the next week, I will receive more sensors to make a test of this idea.
