8  —  TECHNICAL DATA
On the left, it is represented the mechanical interface coordinate system Σ
articulated robot, as defined by ISO 9787:2013. In particular, the center of the coordinate system, O
on the interface surface of the robot tool flange and the Z
symmetry. R
is the i-th revolute joint of the robot and (O
i
robot.
On the right, there is the Tool Coordinate System, Σ
coincides with the center of mass of the hand and its position is defined by the distance from O
 axis is normal to the palm, outgoing positive, and the Y
orientation. This definition implies that Σ
orientation of X
 axis will be on the side of the thumb in the right hand and on the side opposite to the
T
thumb in the left hand.
