thatt was my question.i know from bioloid its only 10%. how does jd stand?

The arms should be straight down when he is standing still. This is one side of the servo movement. Moving 180 positions should put the arms straight up. An offset of 99 would indicate you have the arms attached incorrectly and they need rotating 90 degrees

@Nomad.... See DJ's post (#2). Reset everything back to 90 with 0 offset and start again.... I always calibrate my servos to 90 before I even attach them to brackets or mounts... This is so I have adequate travel in both directions...

ah ok i try blush

batt needs to be charged. thats means the grippers has to come off,then calibrate and put them back on. so value stays low.?

Yes, assemble JD (in standing position) with all the servos as close to 90 as possible... Then tweak later using offsets... I would say set the claw half open with the servo value at 90. That way it can close or fully open equally...

Follow the assembly instructions, pay attention to the orientation of each part, connect them to the correct ports as stated, leave all calibration values at 90 and fine tune any servos which do not sit centre.

There is no need to take anything off to calibrate anything else. Do not over complicate things, just follow the instructions.

sofar the ugly sound is out the schoulders.

problem is some servo's are way off center.hands&schoulder. i had to reposition them to keep a low value. i think am almost there.
