Challenge Problems
Push your limits with advanced challenges
A robotic arm has two segments with link twists of 30 degrees and 45 degrees respectively. If the first segment’s link length is 1 unit, calculate the end-effector position assuming the second segment also has a length of 1 unit.
💡 Hint: Consider how you would multiply the transformation matrices for each segment.
Explain how incorrect link twist values could affect the kinematic analysis of a 6-DOF robotic arm during an operation.
💡 Hint: Think about specific tasks that require precise movements and how deviations can hinder completion.
