Implementation scope and limitations

A method’s presence in the common interface does not mean the corresponding MG400 operation is implemented. Unsupported operations are designed to raise NotImplementedError.

• take_arm() / give_arm(): logical operations, not hardware ownership.

• halt() / stop(): unsupported because equivalence to the common interface’s stop sequence is not established.

• hand_stop(): unimplemented without a specified gripper and I/O mapping.

• drive(): partially implemented; path_blend and J5/J6 have limitations.

• rotate(): plane/angle/center trajectory conversion is unimplemented.

• autocal(): MG400 automatic calibration is unimplemented.

• RobotVarManager: local JSON variable management, not robot-controller variables.

Do not use halt() or stop() as substitutes for a physical safety stop.
