RBX1 Large 3D-Printed Robot Arm
Built and tuned a large 3D-printed 6-axis robot arm using stepper motors and kit-driven mechanical integration.
Problem / context
This was an early hands-on robotics build focused on learning practical kinematics, mechanical integration, and controller tuning through a full physical system. The goal was to move from concept-level understanding to a working large-format robot arm that could be assembled, calibrated, and operated reliably.
Approach
I followed the RBX1 remix kit path and built a large 3D-printed 6-axis arm using stepper-driven actuation. The project centered on:
- mechanical assembly and alignment across multiple printed joints
- stepper motor integration and motion sequencing
- iterative tuning to improve repeatability and smooth motion
- practical troubleshooting of backlash, fit-up, and movement consistency
This was very much a build-test-adjust cycle, with each iteration improving confidence in the whole system.
Outcome / lessons
The project was a strong foundation in real-world robotics integration, where success depends on mechanical details as much as software logic. It reinforced that system performance comes from the full stack: structure, actuation, calibration, and repeatable setup.
