Which problem necessitates trajectory replanning for robotic arms implementing pick-and-place operations?

💡 Explanation

Singularity regions result in infinite joint velocities for finite end-effector motion because the Jacobian matrix loses rank, therefore trajectory replanning prevents instability, rather than simply causing encoder drift or thermal effects.
