Boost Me If you want to support me in developing this project and creating other models. 🔧 Mod #1 – Update from June 23, 2025 In today’s modification, I shortened the robot arm, which significantly improved its agility and responsiveness. In the previous version, the longer arm caused issues when the battery voltage dropped — the servos lacked enough torque to move it properly. With the shorter arm, this is no longer a problem, even under lower power conditions. I also increased the internal space inside the servo housing and widened the cable channels, making it much easier to route and organize the wires neatly within the arm. ⚠️ Note: To ensure full strength and performance, the battery should be fully charged . Otherwise, your robot might get a little lazy. 😉 🎥 Watch it in action: Controlling the arm takes a bit of practice — at first, it's more of a wrestling match than precision work, but with a few tries, you'll feel like a true arm master 😄 This fully functional 3D-printed robotic arm is designed for learning, experimentation, and hobbyist use. The structure is built using the Cyberbrick kit , with control provided by the original Cyberbrick remote , allowing intuitive manipulation of the arm's movements. The build includes 3 servo motors and three servo wire extensions , ensuring smooth motion and easy assembly. All parts were printed using FDM technology with PETG filament , offering excellent durability and thermal resistance. This is a base project that I am actively developing — improvements and additional modules are planned. A video assembly guide will also be available soon to further simplify the setup process. The project serves as a great introduction to robotics and a solid foundation for further custom modifications.
