Challenge Problems
Push your limits with advanced challenges
Consider a robotic arm with three joints attempting to reach a specific point in space. Describe how you would implement the Newton-Raphson method to solve the IK problem, including how you would establish your initial guess.
💡 Hint: Focus on the iterative nature and the need for proper initialization.
A robotic manipulator is often near singular configurations during operation. Describe how the Damped Least Squares method can prevent catastrophic failures in movements.
💡 Hint: Think about how damping can smooth out rapid changes and maintain control.
