[Fernando] sent in a idea about a pet job he’s been working on. It’s an fascinating handle a 3D scanner. He utilized a stepper motor to rotate the item being scanned, as well as an Arduino for control, however the genuine novelty is the method he utilized the sensor. [Fernando] mounted a Sharp GP2D120X on vertical surface, as well as utilized a second stepper motor to raise the sensor during the scan. As you can see in the videos (embedded after the break), this results in the scan being put together in an ascending spiral.
The Sharp sensor is affordable as well as decent, however you’re undoubtedly not going to get incredible accuracy. Still, utilizing the typical of a number of measurements, he ends up with a decent result. Happily, [Fernando] has released the code, as well as it must be simple sufficient to repurpose it with a a lot more precise sensor. It would be fascinating to see a laser-based sensor paired with this code.
