A servo adjustable gripper device for gripping and transporting at least two objects such as boxes includes a frame and at least two gripper assemblies connected with carriages slidably connected with the frame. The gripper device further includes a robotic arm which controls further movement and placement of the boxes on a pallet. The position of the gripper assemblies on the frame is adjustable to provide equal lifting force for a variety of differently sized boxes or for different numbers of boxes.
