The same day I got my revolution jd was the same day his left shoulder servo stopped working . Can you please help? And one note: when I calibrate the servo, it won't work. When I tried rebooting, still wouldn't work. Please help! There is so much it can't do when it's left shoulder won't rotate! Also, I don't want to get any money or payments of any kind involved in this! The robot was expensive enough. Just please let it be easy! Remember.. No calibration, purchases, 3d printing or difficult and complicated methods! my robot is a revolution jd
