MoveIt 2 on a real robot arm with ROS 2 Jazzy: audit the CAD export against the built arm, set up ros2_control, derive the inverse kinematics, build the MoveIt package with the Setup Assistant and drive an ESP32 arm over one USB cable.
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.
Build OmArm Zero, a 6-DOF (5+1 gripper) robotic arm with ESP32 WiFi control. Complete build guide with 3D printing files, wiring diagrams, firmware, and a browser-based control interface. 303 mm reach, 100 g payload (150 g max with the shoulder spring), under $50.
Learn how to build a fully autonomous obstacle avoiding robot car with Arduino, the Arduino Motor Shield Rev3, SG90 servo motor, and HC-SR04 ultrasonic sensor. This complete tutorial includes a bill of materials, step-by-step assembly, wiring diagrams, full Arduino code with explanation, tuning tips, troubleshooting, and FAQ.
Build a 6-DOF robotic arm from 3D printed parts and an Arduino Mega: three MG996R and three SG90 servos on a PCA9685 driver, one potentiometer per servo. Parts list, print settings, assembly, wiring diagram and the full Arduino sketch.
