   Trossen's LeRobot-plugin tutorial trains ACT (--policy.type=act) on Trossen AI Solo/Stationary/Mobile (WidowX AI) datasets and evaluates it on the robot with lerobot-record --robot.type=widowxai_follower_robot / bi_widowxai_follower_robot.

   “We specified the policy with --policy.type=act, which loads configurations from configuration_act.py.”

   Official Trossen plugin README (requires lerobot >= 0.6.0) shows an ACT policy evaluated on a single WidowX AI via lerobot-record --policy.path.

   “Evaluate a trained policy by recording 2 episodes of a cube pickup task with a single WidowX AI robot using the OpenCV camera interface.”

   Trossen-published ACT checkpoint (config.json type=act; train_config dataset hamza-trossen/tshirt-folding-mobile-stationary, whose meta/info.json robot_type=bi_widowxai_follower_robot) with an on-robot eval video and a 6/10 success rate on bimanual t-shirt folding.

   “**ACT** (Action Chunking Transformer) policy for bimanual t-shirt folding on the Trossen AI **stationary** (WidowX AI) platform. Trained with **lerobot**.”
