Abstract:
A cleaning robot including a main body, a pad mounted below the main body to implement cleaning, and a drive assembly to apply drive power to the pad. The drive assembly moves the main body to a target position by adjusting the drive power. The cleaning robot may move at a high speed owing to omni-directional movement thereof without rotation of the main body. Further, the cleaning robot may imitate a human wiping pattern, thus achieving enhanced cleaning efficiency. Furthermore, various cleaning patterns including a straight pattern and a curvilinear pattern may be applied to the cleaning robot.
Abstract:
A cleaning robot having improved traveling performance and a method of controlling the same. The cleaning robot detects a stuck state such as a 'jammed state, 'lifted state', or 'object-caught state' by using a motion instruction or sensor information and quickly escapes from the stuck state caused in various traveling conditions by using a wheel structure capable of changing a total height of the cleaning robot. In addition, a degree of risk and type of the stuck state is predicted before the cleaning robot is in the stuck state so that the cleaning robot may deal with the stuck state in advance. The cleaning robot may escape from the stuck state via rapidly deceleration or quick stopping in accordance with the predicted degree of risk of the stuck state, and the cleaning robot may efficiently deal with the stuck state by using information to select an escaping method suitable for the type of the stuck state.
Abstract:
Disclosed is a robot cleaner capable of reducing the material cost thereof by use of fewer motors, and performing wet cleaning while travelling in all directions and rubbing the floor surface, the robot cleaner includes a plurality of motors generating driving forces, a plurality of pad assemblies configured to rotate by receiving a driving force from one of the plurality of motors, and provided in a tilted manner so that a bottom surface of each of the plurality of pad assemblies has an uneven frictional force with respect to a floor surface, and a tilt gear unit configured to simultaneously vary tilting directions of the plurality of pad assemblies by receiving a driving force from another one of the plurality of motors, wherein the robot clean can travel in all directions depending on a tilting direction and a rotational direction of each of the plurality of pad assemblies.
Abstract:
A cleaning robot includes a main body, a moving assembly to move the main body, a cleaning tool provided at a bottom part of the main body to collect foreign substances on a floor, an imager to collect images around the main body and a controller to recognize motion of a hand by performing image processing of the collected images, identify a control command corresponding to the motion of the hand, plan a moving direction and a moving distance of the main body as movement information based on the control command, and control operations of the moving assembly and the cleaning tool based on the planned movement information. Since the user directly controls movement of the cleaning robot, it is possible to improve interactivity between human and cleaning robot, reduce the user's labour and increase convenience.
Abstract:
A robot cleaner capable of moving in diverse directions and enhancing cleaning efficiency by increasing frictional force between a pad and a floor includes two or more driving units. Each of the driving units includes plural motors, a first subframe connected to at least any one of the motors and configured to rotate by receiving rotational force from the motor, a rotating plate assembly mounted to the first subframe and configured to be slanted with respect to a floor by rotation of the first subframe and to rotate clockwise or counterclockwise by receiving rotational force from another motor, and a pad provided at the rotating plate assembly and configured to contact the floor. When the rotating plate assembly is slanted with respect to the floor, nonuniform frictional force is generated between the pad and the floor, through which the robot cleaner travels.
Abstract:
In accordance with one aspect of the present invention, a cleaner includes a gravity compensation apparatus for applying compensation force to a handle unit, the gravity compensation apparatus having an elastic member connected to one side of the handle unit to generate compensation force and a sliding member for making translational movement in conjunction with turning motion of the handle unit to keep the compensation force in a constant direction regardless of an angle of the handle unit. The torque due to gravity applied to a handle unit of a vacuum cleaner may be precisely compensated, thereby relieving the burden of the user from the weight of the handle unit while the user holds the handle unit for cleaning.
