Abstract
A system for serving a plate on a table includes a robot including a movable base, a body on the movable base, a first pair of arms connected to the body and including a first arm and a second arm; and a first plate holder including a first and a second connectors, the first and second connectors to engage the first and second arms, respectively.
Claims18
A system for serving a plate on a table, comprising:
- a robot comprising a movable base, a body on the movable base, and a first pair of arms connected to the body and comprising a first arm and a second arm spaced apart from the first arm, the first pair of arms configured to complete one or more actions of raising, extending, lowering, and withdrawing to reach at least one position selected from a retracted lower position, an extended lower position, an extended first lifted position, an extended second lifted position, and a retracted second lifted position;
- and
- a first plate holder comprising a first connector and a second connector spaced apart from the first connector, the first connector and the second connector to engage the first arm and the second arm, respectively,
- wherein the system further comprises:
- a plurality of plate holders;
- the robot further comprises a plurality pairs of arms comprising a plurality of first arms and a plurality of second arms, each pair of arms comprising a first arm aligned vertically with other first arms, and a second arm aligned vertically with other second arms, each pair of arms configured to engage with a plate holder of the plurality of plate holders;
- and
- a first endless conveyer belt connected to each of the plurality of first arms and a second endless conveyer belt spaced apart from the first endless conveyer belt, the second endless conveyer belt connected to each of the plurality of second arms, and
- wherein each pair of arms is to be conveyed between a plurality of positions between a topmost position and a lowermost position vertically.

A method of serving a plate on a table, comprising:
- moving a robot to a spot adjacent to the table, the robot carrying a first plate holder, and the first plate holder having a first plate thereon,
- wherein the first plate holder comprises a first connector and a second connector spaced apart from the first connector,
- wherein the robot comprises a movable base, a body on the movable base, and a first pair of arms connected to the body and comprising a first arm and a second arm spaced apart from the first arm, the first pair of arms configured to complete one or more actions of raising, extending, lowering, and withdrawing to reach at least one position selected from a retracted lower position, an extended lower position, an extended first lifted position, an extended second lifted position, and a retracted second lifted position,
- wherein the first arm and the second arm are engaged with the first connector and the second connector during the moving of the robot;
- extending the first arm and the second arm to the extended second lifted position, the first plate holder over a surface of the table;
- moving the first arm and the second arm to the extended first lifted position, the first plate holder being placed on the table;
- moving the first arm and the second arm to the extended lower position to disengage from the first connector and the second connector;
- and
- retracting the first arm and the second arm to the retracted lower position,
- wherein the robot further comprises a plurality pairs of arms comprising a plurality of first arms and a plurality of second arms, each pair of arms comprising a first arm aligned vertically with other first arms, and a second arm aligned vertically with other second arms, each pair of arms configured to engage with a plate holder of a plurality of plate holders, and
- wherein the robot further comprises a first endless conveyer belt connected to each of the plurality of first arms and a second endless conveyer belt spaced apart from the first endless conveyer belt, the second endless conveyer belt connected to each of the plurality of second arms.
