Challenge Problems
Push your limits with advanced challenges
Given a manipulator with specific joint angles, calculate the Jacobian matrix and determine if a singularity exists. Discuss its implications in terms of the robot's operational capabilities.
💡 Hint: Focus on the determinant of the Jacobian for identifying singularities.
Analyze a scenario where your manipulator fails to reach an object because of a singular configuration occurring in the operation. Propose design changes that could prevent this issue.
💡 Hint: Consider alternative paths or joint configurations that maintain operational control.
