I’m a bit confused about the maximum reach of this arm. The spec says 38 cm but the diagram seems to say 30 cm.
I understand the confusion, let me explain this.
There are two dimensions here, the reach would be from the center of the arm (base) on it’s rotation axis but the diagram bellow is showing the envelope not the reach.
Plus there is a mistake in the description, the maximum reach is calculated with the gripper mounted parallel to the ground.
Hope this solve your interrogations.
All the best,
