Abstract
A gripper assembly for use with a media cartridge includes a gripper support and first and second gripper members supported by the gripper support. The gripper members are moveable asymmetrically with respect to the gripper support for gripping the media cartridge.
Claims19
A data storage system comprising:
- a cartridge storage frame for storing multiple media cartridges:
- and
- a robotic arm assembly that is moveable with respect to the cartridge storage frame, the robotic arm assembly including a guide member and a gripper subassembly having a carriage that is moveable along the guide member, the gripper subassembly further including first and second gripper members supported by the carriage, the gripper members being moveable generally linearly and asymmetrically with respect to the carriage for gripping one of the media cartridges.
A data storage system comprising:
- a cartridge storage arrangement for storing multiple media cartridges;
- and
- a robotic device that is moveable with respect to the cartridge storage arrangement for selectively gripping first and second media cartridges having different sizes, the robotic device including a gripper assembly having a gripper support, first and second gripper members supported by the gripper support, and a shaft associated with the gripper members, the first and second gripper members being moveable with respect to the gripper support and along the shaft for gripping each of the first and second media cartridges, wherein the first gripper member is configured to achieve a predetermined position with respect to the gripper support when gripping each of the first and second media cartridges, and the second gripper member is configured to achieve a first closed position when gripping the first media cartridge and a second closed position different than the first closed position when gripping the second media cartridge.
A data storage system comprising:
- a cartridge storage arrangement for storing multiple media cartridges;
- and
- a robotic device that is moveable with respect to the cartridge storage arrangement, the robotic device including a gripper assembly comprising a gripper support, first and second gripper members supported by the gripper support, and an actuator that moves the gripper members asymmetrically with respect to the gripper support for gripping one of the media cartridges, wherein the first gripper member is moveable over a first range of travel, and the second gripper member is moveable over a second range of travel greater than the first range of travel, and wherein the actuator comprises a motor attached to one of the gripper members, a driven member attached to the other gripper member, and a rotatable driving member that extends between the motor and the driven member.
