I selected the bicep but I could not get it to rotate. I even tried going into the graph editor and editing the key frames of each axis on the arm individually but still had no luck. Below is a link to a picture of the setup I have in Blender. Any idea what I am doing wrong?

I'm having the same problem and I'm not set to IK. The rest of it has worked perfectly. Any other ideas?
Going into the Vonn Bots Properties section and tweaking seems to fix.
