That tool is a 6-axis micro manipulator and is essentially a small robotic actuator that is capable of very small, very precise movements. It uses 3D printed parts and low-cost components.

This version features: a rotational manipulator with three axes intersecting at the tip of the robotic arm, allowing for a large degree of freedom; a design for the operating arm to automatically ...
