Robot arm sg90 9g servo
thingiverse
I built this robot arm using the remix from Thingiverse, specifically 1684471. I created an additional base and remote to complete the project. The pca9685 controls the arm, while an sd card module is used for saving positions. To connect joints with servos, I utilized the design found on Thingiverse, thing number 2049935. Testing revealed that a print resolution of 0.2mm works well for the base, as it accommodates the servo without any issues when printed using my Anet A8 printer. Other parts can be printed at various resolutions. Check out this video to see the robot arm in action: https://www.youtube.com/watch?v=W8ThQKJHhLE
