3D-printed tracked robot crawler project

Introduction

This website documents my personal projects. I am a hobby maker and tinkerer with an FDM 3D printer, using it to design, build, and improve practical mechanical parts for my own projects. My work includes small experimental builds such as a 3D-printed model ship and a tracked crawler robot, where 3D printing, electronics, and software come together.

For me, making things is about learning by doing: testing ideas, improving designs step by step, and turning rough concepts into working prototypes.

If you are interested in any of my projects, please feel free to contact me by email.

The crawler robot shown here is my personal ROS 2 hobby build, based on the 3D Printed Tracked Robot Platform by Dejan Nedelkovski from How To Mechatronics.

The content on this website is written in English. Since English is not my native language, and producing all texts entirely by hand would require an unreasonable amount of time, some content has been created or improved with the help of ChatGPT.

Sources are provided wherever applicable. These may include original documentation, but also YouTube videos, tutorials, and other resources based on the original sources.

Although I try to keep all information accurate, mistakes may still occur. If you notice an error, please feel free to send me an email.

Send me an encrypted email

You can use my OpenPGP public key to send me encrypted email.

Download my OpenPGP public key (.asc).
Import it into Kleopatra / Gpg4win or another OpenPGP-compatible application.
Compose an email to one of the email addresses associated with the key.
Enable encryption before sending.

On Windows, this works very easily with Gpg4win and the GpgOL plugin for Outlook. Thunderbird also has built-in OpenPGP support, so no additional plugin is usually required.

Only my public key is published here. The corresponding private key remains private and is required to decrypt messages sent to me.
