The base provides rotational movement for the entire robotic arm and supports all upper assemblies.

The shoulder joint is crucial in the overall pivot strength and versatility of the elbow, wrist, and pinchers.

The elbow provides just a bit more range of motion for difficult to reach areas.

The wrist can rotate, making the eventual grasp at an angle easier.

The pincher group can swivel, adding to the dexterity of the arm overall.

The pincher conveniently rotates to get to that special angle.

The pincher can pinch, or grasp an object and pick it up.
