Challenge Problems
Push your limits with advanced challenges
Assume you have a robot arm with two joints. The first joint rotates by 30° and extends 5 cm, while the second joint can rotate up to 45° from its base. Calculate the resulting position of the end-effector.
💡 Hint: Remember to break down each joint's contribution to the end-effector's position.
For a more complex robot configuration, derive the joint angles required for an end-effector to reach the coordinates (4, 2) using numerical methods for Inverse Kinematics.
💡 Hint: Ensure each step minimizes the error using an iterative approach.
