Robotic system with a robot arm suction control mechanism and method of operation thereof

A robotic system comprising:

• a communication unit configured to:
• receive a sensor reading associated with a target object;
• a control unit, coupled to the communication unit, configured to:
• generate a base plan for performing a task on the target object, wherein generating the base plan includes determining a grip point and one or more grip patterns associated with the grip point for gripping the target object based on a location of the grip point relative to a designated area, a task location, and another target object;
• generate a grip pattern rank based on aligning the target object with the grip pattern location and determining which of the grip patterns at a grip pattern location are for using all of suction grippers associated with the grip patterns to grip the target object;
• implement the base plan for performing the task by operating an actuation unit and one or more of the suction grippers according to the grip pattern rank, to generate an established grip on the target object, wherein the established grip is at the grip pattern location associated with the grip patterns;
• measure the established grip;
• compare the established grip to a force threshold;
• and
• re-grip the target object based on the established grip falling below the force threshold.
