Abstract
A robot system includes a cooking device to heat a cooking container and having an operation unit configured to select a temperature level; a robot configured to control the temperature level and a cooking time of the cooking device; a dust sensor disposed around the cooking device or on the robot to sense a concentration of foreign substances; a temperature sensor disposed around the cooking device or on the robot to sense a temperature of the cooking container or the cooking device; and a controller configured to control the robot in a safe mode such that at least one of the temperature level and the cooking time is varied according to a danger level determined by a concentration sensing value of the dust sensor and a temperature sensing value of the temperature sensor.
Claims19
A robot system comprising:
- a cooking device having an operation unit configured to select a temperature level to heat a cooking container with the temperature level selected by the operation unit;
- a robot configured to control the temperature level and a cooking time of the cooking device;
- a dust sensor disposed on the robot to sense a concentration of foreign substances;
- a temperature sensor disposed on the robot to sense a temperature of the cooking container or the cooking device;
- and
- a controller configured to control the robot in a safe mode so that at least one of the temperature level and the cooking time is varied according to a danger level determined by a concentration sensing value of the dust sensor and a danger level determined by a temperature sensing value of the temperature sensor,
- wherein the robot includes:
- a robot arm having a plurality of arms and at least one arm connector connecting the plurality of arms;
- and
- an end effector installed on the robot arm,
- wherein the dust sensor is installed on the robot arm,
- wherein the temperature sensor includes an infrared sensor installed on the end effector, and
- wherein, when the danger level determined by the concentration sensing value is different from the danger level determined by the temperature sensing value, the controller controls the robot to operate the cooking device with a temperature level and a cooking time according to a higher danger level.
A method of controlling a robot system including a cooking device configured to heat a cooking container, a robot configured to adjust a temperature level and a cooking time of the cooking device and a controller configured to control the robot, the method comprising:
- sensing a foreign substance concentration using a dust sensor disposed on the robot, and a temperature of the cooking container or the cooking device using a temperature sensor disposed on the robot;
- and
- controlling the cooking device variably, by the robot, with a temperature level and a cooking time according to a changed danger level, when a danger level determined by a concentration sensing value sensed by the dust sensor and a danger level determined by a temperature sensing value sensed by the temperature sensor is changed and the danger level is not a lowest level or a highest level,
- wherein the robot includes:
- a robot arm having a plurality of arms and at least one arm connector connecting the plurality of arms;
- and
- an end effector installed on the robot arm,
- wherein the dust sensor is installed on the robot arm,
- wherein the temperature sensor includes an infrared sensor installed on the end effector, and
- wherein, when the danger level determined by the concentration sensing value is different from the danger level determined by the temperature sensing value, the controller controls the robot to operate the cooking device with a temperature level and a cooking time according to a higher danger level.
