Before a robot can move, it first needs to work out which joint angles will place its end effector at the target. That's the job of inverse kinematics.

For a simple two-link robot like this, the solution comes from geometry. By treating the links and the target as a triangle, it can calculate the missing angles needed to reach the target position.

This doesn't just apply to robot arms. Inverse kinematics is used in humanoid robots, quadrupeds, surgical robots, animation, and many other robotic systems whenever a desired position needs to be converted into joint movements.
