Center of Gravity Position of End-Effector
Design an end-effector so that the center of gravity of the end-effector (including workpiece) is
within the range shown in the following figure.
Figure 2-9. Allowable Range of Center of Gravity of End-effector
Moment of Inertia Around J4, J5, and J6
Design an end-effector so that its moments of inertia around J4, J5, and J6 (including mass of
workpiece) do not exceed the maximum allowable moments of inertia of the robot.
l
Maximum allowable moment of inertia around J4 and J5: 0.295 kgm

l
Maximum allowable moment of inertia around J6: 0.045 kgm

When calculating the moment of inertia around J4, J5, and J6 of the end-effector, use the for-
mulas given in the following table. See Moment of Inertia Calculation Examples on page 32.
