VirtuStick extends the range of your mobile 3D-scanner. Two servos and a joystick position the scanner precisely.

Now you can scan large objects, or things out of the reach of your handheld scanner.

How does is work ?: http://youtu.be/IUGenZwRCKo

Thank You :)


This is the prototype of the VirtuStick 3D-Scanner. Follow the project to stay up-to-date with further releases!

Parts List:

1 x Arduino Pro Mini 5V: http://www.physicalcomputing.at/shop/article_A-1110000/Arduino-Pro-Mini-5V_16Mhz.html?sessid=hb8El1u2ztK8uXasIkLmatBMH5foHB3TVViSS2qdVjkr5v9ZSAIHtGYmVzKgHeRq&shop_param=cid%3D3%26aid%3DA-1110000%26

1 x Joystick: http://www.conrad.at/ce/de/product/425664/3D-Joystick-L-x-B-x-H-226-x-167-x-182-mm-mit-Schalter-10-k-60-W-20-

2 x Servo: http://www.amazon.de/gp/product/B003A6183O/ref=oh_details_o02_s00_i00

1 x Asus Xtion Scanner: http://www.amazon.de/gp/product/B005UHB8EK/ref=oh_details_o05_s00_i00

1 x Aluminum pipe 1m x 15mm

1 x Some weight to balance the scanner holder

1 x 9V Battery


1) Print Tray 1 and Tray 2

2) Weld the two parts of the "Scanner Holder" together. I use an old soldering iron and some filament to weld these parts together.

3) Fit the left holder and the left srew in the scanner holder. Weld the scre in the holder.

4) Do the same with the right holder and the right screw

5) Screw the servos in the scanner holder

6) Attach the X Axis to the top servo

7) Balance the scanner holder with the weight

8) Print Tray 3 and weld the Handle and the Joystick holder together

9) Glue the Scanner Holder, the Handle, the Controller holder and the Arm rest on the aluminum rod.

10) Wire the Arduino and upload the firmware

Very cool. I've been planning on making this kind of xy axis hold for a camera platform on a quad for a while. Your code seem to work just like I imagined I would make it. thank you :)
Next step would be how to relay the hold info thru some RC channels :)

I hope you can use this design for your project!

May I ask what your motivation you had to build this?
Specifically which "objects" had you trouble with scanning by hand.
From the extension range I'd guess standing persons.

Inofficial Motiviation: I love 3D-Printing, 3D-Scanning and Arduinos and believe that you can make things better, simply by attaching a Servo and a Joystick :)

Official Motivation: From my experience, I get the best scan results, if the scanner is just 40cm in front of the object and the scanner is parallel to the scan surface. My setup is mobile, so I have to operate the notebook with my left hand and the sanner with my right hand. It is a pain to get good scans (40cm, parallel) of objects near the ground and relatively high objects with this sertup. For example feet, objects you cannot move easily, or the head of statues which are placed on columns.

Ah, now I see how useful this is.
I can imagine how frustrating (and jerky in motion) it can become trying to to take a scan with a laptop in one arm.
