One Inverse-Kinematics Model Crossed Unseen Robot Chains
MorphIK reached roughly five-centimeter error before refinement and sub-centimeter error after one DLS step.
Summary
MorphIK reached roughly five-centimeter error before refinement and sub-centimeter error after one DLS step.
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.
Why it matters
MorphIK reached roughly five-centimeter error before refinement and sub-centimeter error after one DLS step.
Limits and context
- Its samples also cover diverse null-space solutions, but the results remain tied to the evaluated chains, targets and refinement procedure.
