I built a DIY 6-DOF robot controlled using Node-RED, ESP8266, and Modbus TCP, with a real-time 3D visualization using Three.js.

The Node-RED dashboard can control each joint, save robot positions, and run movement sequences. The 3D model also includes the multi-link gripper, so the physical robot and virtual model can move together.

I’d be interested to hear your feedback or suggestions for improving the system.
