The invention provides an auxiliary navigation system of a ceiling projector, which comprises a rotary platform, a controller, a wireless communication module, a laser, an upper computer and a ceiling projector, wherein the ceiling projector is arranged on the rotary platform; the ceiling projector is connected with the controller; two stepping motors are vertically arranged in the rotary platform, and rotary shafts of the two stepping motors are separately connected with two connecting rods which are arranged on the rotary platform; the two stepping motors are connected with the controller; the laser is fixed on the connecting rods; and the upper computer is connected with the controller through the wireless communication module. In the invention, the path planning function is completed by the upper computer, and the planned path information is sent to the projector by a certain method. The path information is projected by the projector to guide a robot to move forwards, and then the robot has no need of any path planning, thereby the data calculation and the processing quantity of the robot main body are reduced, the types and the quantity of the sensors carried by the robot are reduced, and the cost is decreased.
Description
technical field [0001] The invention relates to a robot navigation and positioning system, which belongs to the technical field of robot navigation and positioning. Background technique [0002] At present, the navigation and positioning of the robot mostly rely on the sensors carried by the robot itself (such as ultrasonic sensors, laser sensors, etc.) to perceive the environmental information, and then process the obtained information to determine the next movement strategy of the robot. The ubiquitous phenomenon is that the robot itself needs to perform complex logic operations and data processing, which requires high performance of the robot. At the same time, the robot needs to carry a variety of sensors, some of which are expensive (such as laser sensors). [0003] In order to reduce the cost of robot navigation and positioning, it is particularly important to study how to use other navigation and positioning methods to reduce the requirements for robot performance an...
