    "body_text": "MorphIK is trained entirely on synthetic kinematic chains so one model can propose solutions for previously unseen robots with six to nine degrees of freedom. The authors report about five-centimeter error on real platforms before refinement, below one centimeter after one damped-least-squares step and below one millimeter after three steps in most tested cases. Its samples also cover diverse null-space solutions, but the results remain tied to the evaluated chains, targets and refinement procedure.",
