An embodiment of the invention provides a control method of a cleaning robot. The method includes steps of moving the cleaning robot according to a first direction; keeping moving the cleaning robot according to the first direction when a light detector of the cleaning robot detects a light beam; moving the cleaning robot for a predetermined distance and then stopping the cleaning robot when the light detector does not detect the light beam; and moving the cleaning robot in a second direction.

An embodiment of the invention provides a charging station for a cleaning robot. The charging station includes an IR transmitter and a controller. The IR transmitter outputs a first IR light beam, wherein the IR light beam includes a second boundary and a first boundary which is substantially perpendicular or perpendicular to the charging station and the cleaning robot moves to the charging station along the first boundary. The controller controls the IR transmitter to output the first IR light beam or a second IR light beam. When the controller determines that the cleaning robot is near to the charging station, the controller controls the IR transmitter to output the second IR light beam.

An embodiment of the invention provides a cleaning robot including a light detector and a controller. The light detector detects a light beam. The controller is coupled to the light detector to control the cleaning robot. When the controller determines that the light beam is being output by a charging station, the controller controls the cleaning robot to move to the charging station along a first boundary of the light beam, which is substantially perpendicular to the charging station.

An embodiment of the invention provides a control method for a cleaning robot with a quasi-omnidirectional detector and a directional light detector. The method includes: rotating the non-omnidirectional light detector when the non-omnidirectional light detector detects a light beam; when the non-omnidirectional light detector does not detect the light beam, the non-omnidirectional light detector is stopped from being spun and a rotation angle is estimated; determining a rotation direction according to the rotation angle; rotating the cleaning robot according to the rotation direction; stopping the rotation of the cleaning robot when the directional light detector detects the light beam.

An embodiment of the invention provides a control method of a cleaning robot with a non-omnidirectional light detector. The method includes the steps of: detecting a light beam via the non-omnidirectional light detector; stopping the cleaning robot and spinning the non-omnidirectional light detector when the non-omnidirectional light detector detects the light beam; stopping the spinning of the non-omnidirectional light detector and estimating a first spin angle when the non-omnidirectional light detector does not detect the light beam; and adjusting a moving direction of the cleaning robot according to the first spin angle.

An plug storage structure of a cleaning robot is presented. A charging structure includes a charging base and a main body of an electronic device. The charging base includes a charging terminal and a projecting portion. The main body has an external housing, charging plugs and an plug storage device. When the main body reaches the charging base, the projecting portion triggers the plug storage device, so that the charging plugs protrude from the external housing, so as to be connected to the charging terminal. When the main body leaves the charging base, the plug storage device automatically receives the charging plugs inside the external housing, so as to keep the plugs of the cleaning robot received inside the external housing during cleaning, thereby preventing the plugs of the cleaning robot from colliding with and damaging adjacent furniture.

A cleaning path guidance method combined with a dirt detection mechanism is performed in an automatic cleaning device to generate a cleaning path, so as to guide the automatic cleaning device to clean an area to be cleaned, in which plural grids are defined in the area. The method includes: moving the automatic cleaning device in the area to clear dirt away, and continuously detecting a flow of the dirt cleared away to obtain a dirt level of a current gird; if the dirt level of the current gird exceeds a threshold, marking the grid as a dirty grid; performing an algorithm and finding a shortest path passing through all dirty grids as a cleaning path according to the marked dirty grids; and moving the automatic cleaning device to pass through each dirty grid according to the clean path, so as to clean each dirty gird sequentially.

A transmission assembly and a wheel thereof are presented, and the wheel includes a wheel frame and a tire skin. The wheel frame has a ring-shaped joint surface surrounding the wheel frame, and the joint surface is disposed with at least one slot. The slot has two opposite side walls and at least one stopping wall, and the stopping wall is located between the two side walls. The tire skin is ring-shaped. The tire skin is sleeved on the wheel frame, and attached to the joint surface. The tire skin has at least one protruding rib, and the protruding rib is located in the slot. The stopping wall limits displacement of the protruding rib in a direction of a wheel shaft, and the two side walls limit displacement of the protruding rib in a direction of rotation, thus achieving a good combination effect between the tire skin and the wheel frame.

Transmission assembly and wheel thereof

The dust container is disposed in the dust collector, so as to receive dirt drawn by the dust collector. The dust container includes a fastening device. The dust container can be taken out from the dust collector by operating the fastening device in one operation, and then installed back into the dust collector after the dirt is cleared away, thereby completing actions of disassembling, assembling and clearing the dust container quickly and cleanly.

Dust container and dust collector using the same

The present invention disclosed a moving route planning method for mobile robot device, which provides the moving route on a physical site for the mobile robot device. The method includes a first and a second steps; in which, the first step is to generate a relative mesh grid diagram based on a physical site, and the mesh grid map comprises a plurality of map grids containing hindrance parameter values, wherein the hindrance parameter values for each map grid are determined by the locations of hindrances within the physical site at relative locations; and, the second step is to continuously expand the map grid from the start point and the target point toward the neighbored map grids until the expanded map grids meet with each other, and to define each map grid in the expansion traces for meeting with each other as the moving route.
