A robot hand includes a first proximal end finger having a first protrusion at a distal end of the first proximal end finger, a first distal end finger that is connected to the first proximal end finger in a relatively rotatable manner and has a first cutout allowable the first protrusion to pass, a second proximal end finger having a second protrusion at a distal end of the second proximal end finger, a second distal end finger that is connected to the second proximal end finger in a relatively rotatable manner and has a second cutout allowable the second protrusion to pass, an opening and closing drive unit that relatively moves the second proximal end finger with respect to the first proximal end finger, a first rotation drive unit that relatively rotates the first distal end finger with respect to the first proximal end finger, a second rotation drive unit that relatively rotates the second distal end finger with respect to the second proximal end finger, and a controller that actuates the opening and closing drive unit, the first rotation drive unit, and the second rotation drive unit.

Various aspects of robotic grippers are disclosed herein. In one aspect, a robotic gripper may include three gripper fingers arranged on a mechanical end effector, the three gripper fingers configured to translate radially when actuated to contact and align with a gripper interface located on a part to enable manipulation of the part. In various embodiments, each gripper finger may include an elongated portion configured to contact an outer surface of the gripper interface when the gripper fingers are actuated. Each gripper finger may further include a hook portion configured to contact an inner surface of the gripper interface opposing the outer surface. In various embodiments, the hook portion may include a receptacle positioned to align with a complementary protrusion on the gripper interface.

A coffee machine includes a housing that comprises a first platform, a second platform, a first robotic arm, a second robotic arm, and an information handling system. The information handling system comprises a memory and a processor. The memory is configured to receive and store a multiple beverage orders in a log and to monitor a position of a first cup and a second cup corresponding to a first beverage order and a second beverage order. The processor is configured to initiate a second sub-step of the second beverage order prior to initiating a second sub-step of the first beverage order in response to determining that a first sub-step of the second beverage order has terminated first and to transmit to the log of the memory that the second cup is at the third designated position for the second sub-step of the second beverage order to be performed.

A coffee machine includes a first housing and a second housing, wherein the second housing is disposed on top of the first housing. The second housing comprises a first platform, a second platform disposed below the first platform, and a lift disposed at a first side of the second housing and configured to translate between the first platform and the second platform. The second housing further comprises a first robotic arm disposed above the first platform, a second robotic arm disposed between the second platform and the first platform, and a coffee brewing machine actionable to dispense one or more fluids into a cup. The coffee machine further comprises an information handling system comprising a processor, wherein the processor is configured to actuate the first robotic arm, the second robotic arm, the coffee brewing machine, and the lift.
