An autonomous cleaning robot includes a controller configured to execute instructions to perform one or more operations. The one or more operations includes operating a drive system to move the cleaning robot in a forward drive direction along a first obstacle surface with a side surface of the cleaning robot facing the first obstacle surface, then operating the drive system to turn the cleaning robot such that the side surface of the cleaning robot faces a second obstacle surface, then operating the drive system to move the cleaning robot in a rearward drive direction along the second obstacle surface, and then operating the drive system to move the cleaning robot in the forward drive direction along the second obstacle surface.

The present disclosure relates to a robot cleaner, more particularly, to a robot cleaner that may be escaped from a trapped state by an escaping unit formed in an inner surface of a wheel, when a body of the robot cleaner is caught in a protrusion to put the robot cleaner in a trapped state where the robot cleaner cannot run during the running on the floor of a cleaning area.

The present disclosure provides an adjusting structure of a floor brush wheel, which includes a bottom housing, a top housing, a transmission member, a first pulley assembly, and a second pulley assembly. The bottom housing and the top housing are fastened to form a receiving cavity. The transmission member is received in the receiving cavity and movably connected to the bottom housing. The first pulley assembly and the second pulley assembly are movably connected to the bottom housing, respectively. One end of the transmission member abuts against the first pulley assembly, and the other end of the transmission member abuts against the second pulley assembly. When the transmission member slides in a first direction, the first pulley assembly and the second pulley assembly are pressed by the transmission member to slide in a direction away from the bottom housing.

The present disclosure provides a method for controlling a robot cleaner including a travel operation in which the robot cleaner travels, a recognition operation in which when the robot cleaner contacts an obstacle during the travel, the robot cleaner determines whether the obstacle is pushed by the robot cleaner and slides, and an obstacle bypass operation in which upon determination that the obstacle is the pushed-and-sliding obstacle, the robot cleaner stops the travel and then bypasses the pushed-and-sliding obstacle.

A device for receiving signals via an electrically driveable or adjustable furniture element includes a receiving device for receiving at least one wirelessly transmitted signal, and the at least one wirelessly transmitted signal that has been received by the receiving device can be transmitted on to a furniture element. The receiving device is designed such that the at least one wirelessly transmitted signal can be received and processed via a first transmission protocol and a second transmission protocol, wherein the first transmission protocol is different from the second transmission protocol.

A dust collector including a body with an intake portion and an exhaust portion includes a filter, a filter support that supports the filter, a motor case protruding from an inner surface of the body, and a vibration motor accommodated in the motor case. The body accommodates the filter support. A portion on the tip side of the motor case is at a position where it is allowed to come into contact with the filter support when the vibration motor is driven.

The present disclosure relates to a mobile robot, and more particularly to a mobile robot, including: a bumper which surrounds at least a portion of an outer circumference of the body; position restoring modules having an elastic member and disposed to be symmetrical to each other; a bumper guide module, having a guide hole and a protruding guider which moves inside the guide hole; and impact sensing modules configured to sense impact and disposed to be symmetrical to each other.

A robot cleaner having a shielding module provided under a cleaner body is provided. The shielding module includes a cam and a hiding plate which rotate with the same phase angle about a same rotating shaft. The distance between the center of the hiding plate and the center of the rotating shaft is longer than the distance between a contact point on a cam surface of the cam and the center of the rotating shaft. A guide protrusion of a bumper is in contact with the cam surface at the contact point. Therefore, the rotation movement speed of the hiding plate which rotates to hide a cliff sensor is much faster than the inner movement speed of the bumper, thereby improving sensitivity to the detection of a collision between the bumper and an obstacle by using the cliff sensor.

The present invention relates to a robot cleaner. The robot cleaner comprises: a cleaner body equipped with a driving wheel; and a cleaning nozzle mounted inside a downwardly open opening portion in a lower portion of the cleaner body so as to be able to ascend and descend. The cleaning nozzle can be supported by a plurality of ascending/descending guides and a plurality of auxiliary ascending/descending guides so that the cleaning nozzle can ascend and descend relative to the cleaner body according to changes in the height of a cleaning surface on which the cleaner body travels. Accordingly, the cleaning to nozzle rises upon being pressed by a compressible floor such as a carpet, thus solving the problem of the cleaning nozzle catching on the cleaning surface. Therefore, travel performance can be improved, and the load on a brush driving part can be reduced.

A robot cleaner includes a main body that autonomously travels, a suction nozzle configured to move up and down or swing with respect to the main body, and a support to support the suction nozzle. The robot cleaner may respond to a change in a height of a floor to improve travel performance and may respond better to obstacles. Even when a height difference of the floor is large, cleaning performance may be improved by maintaining contact and increasing a suction pressure of the suction nozzle.
