Load on the Arm
When you attach a camera or other devices to the arm, calculate the weight as the equivalent
of the shaft. Then, add this to the load and enter the total weight to the Weight parameter
Equivalent Weight Formula
<Example> A "1 kg" camera is attached to the end of the T3-B series arm (225 mm away from
the rotation center of Joint #2) with a load weight of "1 kg".
