The present disclosure provides an autonomous mobile apparatus and a control method thereof. The method includes: starting a SLAM mode; obtaining first image data captured by a first camera; extracting a first tag image of positioning tag(s) from the first image data; calculating a three-dimensional camera coordinate of feature points of the positioning tag(s) in a first camera coordinate system of the first camera based on the first tag image; calculating a three-dimensional world coordinate of the feature points of the positioning tag(s) in a world coordinate system based on a first camera pose of the first camera when obtaining the first image data in the world coordinate system and the three-dimensional camera coordinate; and generating a map file based on the three-dimensional world coordinate of the feature points of the positioning tag(s).

A method for localizing a vehicle comprises transmitting first position data related to a first position of the vehicle at a first point in time from the vehicle to a server. The server computes second position data related to the first position of the vehicle at the first point in time based on the received first position data. The server transmits the second position data from the server to the vehicle. The vehicle computes third position data related to a second position of the vehicle at a second point in time based on the received second position data. The second point in time is later than the first point in time.

A system providing a barrier for an autonomous floor cleaner includes an artificial barrier generator that radiates one or more infrared signals. An autonomous floor cleaner can be configured to detect the infrared signals, and can react by altering course. Methods for containing an autonomous floor cleaner within a user-determined boundary are disclosed.

An infrared transceiver unit (107, 108), a detection apparatus, a multi-infrared detection apparatus and an obstacle avoidance robot. The infrared transceiver unit (107, 108) includes a mounting skewed slot, an infrared emitting source (1085), and two groups of infrared receiving sources (1083, 1084), wherein a sensing direction of one group of infrared receiving sources (1084) and an emitting direction of the infrared emitting source (1085) both face one side of a sensing center line (L) of the mounting skewed slot, and the sensing direction of the other group of infrared receiving sources (1083) faces the other side of the sensing center line (L) of the mounting skewed slot, so that one of the infrared receiving sources (1083, 1084) receives infrared modulation light emitted by the infrared emitting source and reflected by an obstacle. Two infrared transceiver units (107, 108) are respectively arranged on a left end and a right end of an obstacle avoidance robot, and the infrared transceiver unit (107, 108) arranged on one end of the robot receives the infrared modulation light emitted by the infrared transceiver unit (107, 108) arranged on the other end, or the infrared modulation light emitted by the infrared transceiver unit (107, 108) arranged on either end and reflected by the obstacle.

The invention comprises a method and a system for conveying a mobile robot in an elevator involving the monitoring of elevator operating components and of persons surrounding the elevator and operating the elevator by selecting a floor to which the mobile robot is to move. In one aspect an inertial sensor is used to learn or determine the number of floors. The robot may also have methods implemented to assess the floor space inside the elevator or to position itself in front of the elevator in such a way that it can, for example, monitor the operation of elevator operating components without being perceived as an obstacle from the elevator users' perspective.

A fluctuating oscillator includes: a processor including a digital circuit, and the processor includes a random variable generation unit that generates a random variable, a lookup table that stores a waveform signal in advance, a computation unit that imparts fluctuation to the waveform signal based on the waveform signal read from the lookup table, the random variable generated by the random variable generation unit, and a pulse signal to be fed back, a threshold discrimination unit that generates a pulse signal by comparing a fluctuating signal output from the computation unit with a predetermined threshold, and a feedback loop that causes the pulse signal to be fed back to the computation unit.

A control method for light sources of a vision machine and the vision machine. The control method includes the following steps: activating at least one first light source among n light sources to sense spatial information of an object in a field of view; and selectively activating the n light sources according to the spatial information of a sensed object; wherein the n light sources are distributed on a periphery of a front mirror surface of a lens of the vision machine, and n is a natural number greater than or equal to 2. The embodiment of the present disclosure enlarges the field of view of the vision machine, capable of providing corresponding light illumination based on environmental requirements, reducing the interference signal caused by reflection of a single light source, expanding the sensing range of the vision machine, and improving the sensing ability.

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 pivotably 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 based on a pivot angle formed by the auxiliary cleaning unit with respect to a travel direction of the body when the obstacle is sensed.

A guide-type virtual wall system is provided. The system comprises a beacon (11, 44) and a robot (12), wherein a transmission module of the beacon (11, 44) directionally transmits a first signal, and an area covered by the first signal defines a beacon signal area (13). The robot (12) comprises a beacon signal receiving module corresponding to the beacon signal transmission module. When the robot (12) enters the beacon signal area (13) and the beacon signal receiving module detects the first signal, the robot (12) advances towards the direction of the beacon (11, 44) until it detects a second signal, and then the robot (12) crosses over or exits from the beacon signal area (13). The system can restrict the robot (12) from entering a certain area, wherein the area where a virtual wall is located is not missed, and the robot (12) is also enabled to cross over the virtual wall to enter the restricted area when required.

The present invention is a mobile robot with an attached cleaning element and capable of autonomously seeking areas with low overhead clearance. In the preferred embodiment is a mobile robot using an array of upward facing distance sensors in communication with a controller to detect the presence of obstructions or surfaces above the apparatus. The controller directs the movements of the mobile robot through the use of a drive system, using pattern recognition to avoid becoming stuck and using random movements to increase floor coverage.
