Thank you so much for sharing this! I really enjoyed it. You have a typo on your slide @14:25. Your cosine rule (2nd line) on the right had side of the equation should not have the '-r**2' term. It should read r**2 = a1**2 + a2**2 - 2*a1*a2*cos(alpha).
Hi Kevin, please can make a dedicated video or stream for 6 DOF Robot arm, it forward kinematics and Inverse kinematics calculations, and approach for these calculations. because your style explaining things is amazing.
