Modular 6-axis educational robot arm

About this part

A modular 6‑axis robot arm system for education and experiments. It supports different kinematic chains and uses direct drive with micro and standard‑size servos. Each intermediate module is assembled from two printed halves with a 20 × 32 × 7 mm bearing and M3 screws. It can be driven by a low‑cost microcontroller.

Servos, bearings, screws and electronics are not included; only the printed parts are supplied. Manufactured by Eksenix using PETG via FDM 3D printing (color selectable). Please compare the dimensions with your project before ordering.

Compatibility

- 20 × 32 × 7 mm bearing - M3 screws - Direct drive with micro and standard‑size servos - Controllable with a microcontroller
