Designing a Low-Cost 6-Axis Robot Arm Simulation

One sentence gets the model to design a buildable six-joint robot arm for $122, with the finished video showing its 3D structure and a physics simulation of its kinematics. The author claims no CAD skills and no prior robot-building experience, having only watched Stanford's free robotics course beforehand, then entered the prompt and went to sleep. A good fit for hardware-maker and robotics-intro short videos.
