TL;DR
This paper resolves a long-standing open problem in computational geometry by proving that polygonal chains in the plane cannot become locked, ensuring they can always be moved to a straight configuration.
Contribution
It provides a definitive proof that polygonal chains in the plane cannot lock, settling a decades-old question in the field.
Findings
Polygonal chains cannot lock in the plane.
The proof resolves a long-standing open problem.
Implications for motion planning in robotics.
Abstract
