COM of the Ex-106 and Rx-64

I am not sure that your simulation demands a very accurate measurement.

Based on the other servos, I would suggest that the COM along the long axis of the servo and parallel to the servo output shaft will lie in a central plane.. The COM along the long axis a right angles to the servo output shaft ( parallel to output disk will be shifted towards the output disk because the gears are that end and the electronics at the other ( maybe 60/40 ratio).

About the short axis, the motor is at one end and the output shaft at the other. The motor is heavier, so I would estimate again about 60/40 ratio.

While awaiting true data, I suggest you tstart with these valuse and do a sensitivity check on the simulation.

not that it matters alot, but might be better to call it COG, center of gravity, since COM already reffers to your com-port.
Ontopic; sorry i dont know, if you/some1 find out please share

Yes, By COM I mean Center of mass.

I was thinking COM was Centre of Mass.

If someone can send me some freebies, I am happy to measure it. I should probably have a dozen of each for about 2 years to get statistically significant results and be sure it doesn't change over time !

by COM do you mean communications / protocol / interface ?

hi,

I am doing a project on 3D simulation of a Robot. Has someone figured out the COM of the Robotis motors?
