Some of my more popular projects on GitHub!

  • Faze4 robotic arm is a large 3d printed robotic arm that uses 3d printed cycloidal gearboxes and stepper motors. It is designed to be sleek and hides all the wires. It is now used worldwide by individuals and educational institutions for research and development.

  • CM6 is safe, compliant, and most of all cheap. CM6 is a 3D printable COBOT robotic arm that uses QDD (Quasi direct drive actuators). QDD gives CM6 passive compliance which makes it behave like a human arm. Finalist in hackaday prize competition and used by people around the world for the development of Cobots!

Projects I am working on:

  • Small industrial and educational 6-axis robot arm.
  • SCARA robot.
  • Software for easy programming of robotic arms.
  • BLDC drivers for dynamic robots.
  • Compliant and modular gripper capable of detecting when it grasped an object.
  • 3D printing farm automation

By donating you help me develop and fund all these projects and make the development quicker. In return, you get my everlasting gratitude and access to most files used to create these projects (CAD models, PCB files, schematics...). In the future, I would love to make everything I do open-source.

@PCrnjak

I will be able to put more time into my open-source projects. Everybody knows hardware is expensive and I want to make outstandingly documented robotics projects that take time and money.
