Pick quality determination

A sorting system, comprising:

• a pressure meter configured to sense a pressure associated with an airflow through a gripper mechanism associated with a diverting mechanism over time during a pick operation that is performed on a target object;
• and
• one or more processors configured to:
• receive, from the pressure meter, the sensed pressure associated with the airflow through the gripper mechanism over time as a pressure sequence associated with the pick operation on the target object;
• and
• correlate the pressure sequence associated with the pick operation on the target object with a representative pressure sequence associated with a corresponding pick quality type to determine whether the pick operation on the target object was successful or not.
