Cuspidal-manipulator path-planning paper identifies ABB GoFa kinematic behavior

Evidence notes
- The paper studies path planning for cuspidal 6R manipulators, where inverse-kinematics branch choices can make a task-space path infeasible.
- The authors identify ABB GoFa as cuspidal and propose graph-based planning over inverse-kinematics solutions.
- The work adds research context for GoFa motion planning and optimization in industrial toolpath settings.
