#### Inverse Kinematics for a 2-Joint Robot Arm Using Geometry

lesson

We revisit the simple 2-link planar robot and determine the inverse kinematic function using simple geometry and trigonometry.

We recap the important points from this lecture.

lesson

We learn how to describe the orientation of an object by a 3×3 rotation matrix which has some special properties.
