Train a No-Code AI Robotic Arm with LeRobot and SO-101

Brogan M. Pratt walks through assembling an SO-101 arm, installing Hugging Face LeRobot, recording teleoperation data, and training an ACT model. The chapters cover hardware setup, dataset creation, training, and testing the arm on a pick-and-place task.
