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.

Thanks to 3D printing and inexpensive controllers, a robot arm doesn’t need to break the bank anymore. Case in point? [Build Some Stuff] did a good-looking compact arm with servos for under $60 ...

The robot arm is controlled using a touchscreen application loaded onto an old smartphone hose inside a control box, making the design of the robotic arm completely self-contained.

A major challenge of robotic arms is the weight of the actuators, especially closer to the end of the arm. The long lever arm means more torque is required from the other actuators, and everything … ...
