The application provides a structured light module and an autonomous mobile device. The structured light module includes a first camera and line laser emitters for collecting a first environmental image containing laser stripes generated when the line laser encounters an object. The structured light module can also capture a visible light image through a second environmental image that does not contain laser stripes. Both the first and second environmental images can help to detect more accurate and richer environmental information, expanding the application range of laser sensors.

A traveling vehicle operable to travel along a predetermined travel path, and includes an indicator with switchable lighting states, an imager to capture an image of a preceding traveling vehicle located in front of a subject traveling vehicle to include the indicator provided to the preceding traveling vehicle in the captured image, and a controller to control traveling of the subject traveling vehicle based on a determination result of the lighting states of the indicator included in the captured image. The indicator includes a first indicator to notify a state of the subject traveling vehicle, and a second indicator to include both images of the indicator in a lit state and the indicator in an unlit state in the captured image.

A linear laser module and a self-moving device are provided. The linear laser module is applied for the self-moving device, and includes: a camera apparatus for acquiring an ambient image; at least one linear laser emitter, disposed on both sides of the camera apparatus, and configured to emit a laser having a linear projection, the camera apparatus working in coordination with the at least one linear laser emitter; and a return-to-pile positioning apparatus for receiving a first infrared signal emitted by a charging pile. Thereby, a sensing component communicatively connected to the charging pile, and a sensing component for measuring a road condition in front of a device body, are integrated into the linear laser module, thereby allowing a modular design of a sensing system, which is convenient for assembly and repair.

A sports field having automatic line marking capabilities. The sports field includes a robotic total station in communication with a mobile marking robot configured for marking and re-marking of lines on a sports field.

An unmanned vehicle is disposed in a predetermined area, and is provided with a lidar unit that emits light beams to acquire light sensing data pieces, each containing distance information and a light intensity value. The unmanned vehicle acquires a detection value representing a number of those of the light sensing data pieces whose light intensity values are greater than a light intensity threshold. When the detection value is zero, a first pose of the unmanned vehicle is calculated based on a moving speed and a moving direction of the unmanned vehicle. When the detection value is not zero, a second pose of the unmanned vehicle is calculated based on the moving speed, the moving direction and positions of multiple reflective marks disposed in the predetermined area, as recorded in an area map of the predetermined area.

A system is provided for controlling a grain cart relative to a vehicle. The grain cart includes an edge extending between a front edge and a rear edge, and the vehicle includes a side edge extending between a front end and a rear end. The system comprises a ranging device and a controller. The ranging device is configured to determine a position and orientation of the side edge relative to the grain cart. The controller is configured to determine a front distance between the front edge of the grain cart and the side edge, determine a rear distance between the rear edge of the grain cart and the side edge, determine a maximum distance between the front distance and the rear distance, determine whether the maximum distance is greater than a maximum threshold, and if the controller determines that the maximum distance is greater than the maximum threshold, the controller is configured to steer the grain cart to reduce the maximum distance.

A portable robotic platform system and method for automatically detecting, locating, and marking underground assets are provided. The portable robotic platform includes a housing with a sensor module including ground penetrating radar (GPR), LiDAR, and electromagnetic (EM) sensors. The robotic platform automatically collects GPR and EM data and uses onboard post-processing techniques to interpret the sensor data and identify the location(s) of underground infrastructure. The portable robotic platform can be deployed to apply paint to a ground surface to identify the located underground assets.

A robot includes: a travel unit configured to move the robot; a light detection and ranging (LiDAR) sensor; and at least one processor configured to: obtain first distance data between the robot and objects around the robot by using the LiDAR sensor, obtain line data corresponding to an object having a line shape based on the first distance data, control the travel based on the line data to move the robot, track the line data based on second distance data obtained by the LiDAR sensor while the robot moves, and identify a curvature value of the tracked line data, and identify whether the LiDAR sensor is defective based on a change in the curvature value.

The invention relates to the provision of a robotic machine apparatus, a movement navigation system for said robotic machine and a method of providing guidance for said robotic machine within an environment, and most typically, a confined and potentially hazardous environment. The movement navigation is provided to be operate within the environment and provide guidance remotely from personnel who are located outside of said environment. The apparatus includes means to emit at least one signal through a window of said machine and means to receive a reflected return signal from an object in or a surface of the said environment through said or another window so as to provide data to determine the location of the robotic machine and guide the movement of the machine within the environment.

A shelf positioning method of a transporting device is provided. The transporting device includes a range finding device and a controller. The shelf is located in a storage area within a specific space. The shelf positioning method is described below. A global coordinate, a global orientation angle, and dimension parameters of the storage area are input to the controller.
