Various example embodiments described herein relate to an item manipulation system including a control system and a robotic arm coupled to the control system. The item manipulation system includes an end effector communicatively coupled to the control system and defines a first end and a second end. The first end of the end effector is rotatably engaged to the robotic arm. The item manipulation system also includes a gripper unit attached to the second end of the end effector. The gripper unit is configured to grip the item. The gripper unit includes at least one flexible suction cup and at least one rigid gripper. Each of the flexible suction cup and the at least one rigid gripper engage a surface of the item based on vacuum suction force generated through the at least one flexible suction cup or the at least one rigid gripper.
