  “ConnectionError: Read failed due to communication error on port /dev/ttyACM0 for group_key Torque_Enable_shoulder_pan_shoulder_lift_elbow_flex_wrist_flex_wrist_roll_gripper: [TxRxResult] There is no status packet!”

   

  Could anyone explain why this error is occurring? It was working fine yesterday, but it started failing today.

  Maybe something wrong with connectiong or control borads.

  The improtant thing is that avoid hot-swapping servos or control boards (always power off before connecting/disconnecting).

  If the system functioned normally the previous day, prioritize checking for loose cable connections or maybe LeRobot source code updated.
