How to Add MoveIt 2 to Your Robot Arm — Motion Planning + Real Hardware Control (Full Guide)

In Part 2 I built a digital twin. Now the arm plans its own moves. This video covers everything from motion planning theory to running MoveIt 2 on real hardware — inverse kinematics, trajectory planning, the MoveIt Setup Assistant, Gazebo simulation, a Python API, and a custom serial bridge to control the physical arm over USB. No MoveIt experience required. Every concept gets a visual explanation first, then we build it step by step: configure the planning groups, set up controllers, run the demo with mock hardware, simulate in Gazebo, write a Python motion script, and finally bridge the gap to the real servos.
