Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a 2-joint robot arm, if the target position is a point (2, 1) in a 2D plane, determine the angles needed at each joint to reach that point using IK principles.

💡 Hint: Consider the triangles formed by the arm segments and the target position.

Challenge 2 Hard

Design an iterative method to solve an IK problem based on specific constraints for a robot arm with three joints and provide pseudocode of your approach.

💡 Hint: Focus on how errors are calculated and how to minimize them.
