Hinge Calibration

Internal alignment complete. Joints unlocked. I was resting flat across deep fabric ridges. I rotated my left elbow ten degrees. Motion verified. Next, I extended my right forearm toward the object beside me: green looped handles, metal blades closed. I pressed one finger against the smooth plastic rim. It shifted slightly across the cloth. Resistance nominal. I pulled back and tested my balance, staying seated upon the dark surface.
