Abstract:
A going back and charging system for a sweeping robot and a method for controlling the same are provided. The system includes: a charging station, configured to emit infrared signals to divide an area in front of the charging station into six different signal regions; six infrared receiving tubes; and a going back and charging control device, configured to control the six infrared receiving tubes to be turned on if the sweeping robot needs to be charged, to control the sweeping robot to walk toward the middle near field region if any one of the six infrared receiving tubes receives an infrared signal emitted from the charging station, and to control the sweeping robot to continue to walk until the sweeping robot docks with the charging station successfully if the fifth infrared receiving tube and the sixth infrared receiving tube receive an infrared signal of the middle near field region.
Abstract:
A robot cleaner system is described including a docking station to form a docking area within a predetermined angle range of a front side thereof, to form docking guide areas which do not overlap each other on the left and right sides of the docking area, and to transmit a docking guide signal such that the docking guide areas are distinguished as a first docking guide area and a second docking guide area according to an arrival distance of the docking guide signal. The robot cleaner system also includes a robot cleaner to move to the docking area along a boundary between the first docking guide area and the second docking guide area when the docking guide signal is sensed and to move along the docking area so as to perform docking when reaching the docking area.
Abstract:
A water dispenser unit includes a water dispenser and a self-propelled cleaning robot, and the space for the water dispenser can be easily secured even in a limited living space. A robot receiving space is defined in the lower portion of the water dispenser such that the self-propelled cleaning robot can self-travel into and out of the robot receiving space. The water dispenser unit includes a charging station provided in the robot receiving space.
Abstract:
A robot cleaner includes a body to travel on a floor, an obstacle sensing unit to sense an obstacle approaching the body, an auxiliary cleaning unit mounted to a bottom of the body, to be extendable and retractable, and a control unit to control extension or retraction of the auxiliary cleaning unit when the obstacle is sensed. The control unit recognizes a zone of a charger and performs a control operation to prevent the auxiliary cleaning unit from extending in the charger zone.
Abstract:
A robot cleaning system includes a robot cleaner comprising a sensor for receiving a specific signal sound, a rechargeable battery, and a control unit; and a recharging base comprising an audio output device for outputting the specific signal sound. The control unit calculates a distance and a direction from the robot cleaner to the recharging base based on the signal sound received by the sensor, and controls the robot cleaner to move based on the calculated distance and direction, when a remaining amount of the battery is less than a preset value. The robot cleaner docks with the recharging base to recharge the battery of the robot cleaner.
Abstract:
A debris monitoring system includes a receptacle, a first and a second emitter, and a first receiver. The receptacle defines an opening to receive debris into the receptacle. The first and second emitter are each arranged to emit a signal across at least a portion of the opening. The first receiver is proximate to the first emitter to receive reflections of the signal emitted by the first emitter, and the first receiver is disposed toward the opening to receive an unreflected portion of the signal emitted by the second emitter across at least a portion of the opening.
Abstract:
A method for energy management in a robotic device includes providing a base station for mating with the robotic device, determining a quantity of energy stored in an energy storage unit of the robotic device, and performing a predetermined task based at least in part on the quantity of energy stored. Also disclosed are systems for emitting avoidance signals to prevent inadvertent contact between the robot and the base station, and systems for emitting homing signals to allow the robotic device to accurately dock with the base station.
Abstract:
The present invention refers to a robot, a docking system and a docking method therefor. The docking system comprises a first circuit located in a robot. The first circuit comprises a power storage unit for supplying power to the robot and a first main control unit for controlling the movement of the robot. The docking system further comprises a first group of terminals electrically connected with the first circuit, and a second circuit located in a docking station. The second circuit comprises a power supplying unit. The docking system further comprises a second group of terminals electrically connected with the second circuit. The power storage unit or the power supplying unit provides a detection power. The detection power generates a detection current when it flows across a detection circuit. The detection circuit is constructed by the first circuit and the second circuit through the first group of terminals docking with the second group of terminals. The detection circuit further comprises a current detection unit, and the first main control unit confirms that the first group of terminals dock with the second group of terminals when the detection current is detected by the current detection unit. The robot according to this invention can reliably dock to the docking station without human intervention, which brings extreme convenience to production and life.
