Four 3D printed robot arms compared: the Arduino arm, the Bluetooth arm, the OmArm Zero with ESP32 and ROS 2, and the OmArm One on ball bearings. What 6-axis means, which to build first, and where the files are.
Export a URDF from Fusion 360, audit it, correct joint directions, zeros and limits so the model matches the real OmArm One, and run it in RViz and Gazebo Harmonic. Part 2 of the OmArm One series, for ROS 2 Jazzy.
Pair a PS3 controller to an ESP32 with Bluepad32 and drive a 3D printed 7-DOF (6+1 gripper) robot arm: velocity sticks, four speed levels, a recorded pose sequence and a latching stop, with no PC in the loop.
Build a 3D printed robot arm with 7 DOF on real ball bearings: 485 mm reach, 200 g payload, full BOM, 16 assembly animations and ESP32 web control.
