Hi, I have recently purchased a JD Humanoid Robot and am having a pretty fun time using it. However, the servo, or joint in JD’s right upper leg does not go up past a 45 degree angle. I can’t see anything that might be blocking it or in it’s way and I’m not sure why else it wouldn’t go all the way up like the left leg. Because of this setback, JD can’t do many things including stand from a sitting position. I’m not sure what to do about this problem.
