Need some help using the robotic arm on the Roborock Saros Z70? Here are a few tips and tricks to improve its performance, plus a look at its limitations.

Learn how to build your own desktop fully functional robot arm powered by Arduino hardware and assembled using 3D printed parts.

You then need to train the speech recognition software by feeding it your voice samples (you don't want your robotic arm responding to anyone else, right?).

But what if there was a way to bridge that gap? This robot arm guide offers a guide to building a mini robotic arm using Arduino, complete with 3D-printed parts and easy-to-follow instructions.
