Cleaning robot

Abstract

The invention provides a cleaning robot which comprises a motion unit, a motion sensor, a monocular camera, a storage unit, a data processing unit, a cleaning unit and a shell. The motion sensor acquires motion parameters of the cleaning robot in the motion process. The monocular camera is used for shooting images and is arranged in a slope face which is located at the front end of the shell and inclines upwards in the forward motion direction, the monocular camera and the slope face are approximately in the same direction, and an acute angle is formed by the direction of the monocular cameraand the forward motion direction of the cleaning robot. The data processing unit is used for acquiring the images shot by the monocular camera and the motion parameters of the motion sensor, carryingout locating, mapping and route planning on the cleaning robot and controlling the motion unit to operate according to a planned route. According to the cleaning robot, the simple-structure monocularcamera with the elevation angle being an acute angle is arranged, the accuracy of locating and mapping of the cleaning robot is improved, and therefore the route planning / navigation effect is improved.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to a cleaning robot. Background technique [0002] In recent years, cleaning robots have developed rapidly. For this type of robots, the most important point is to achieve comprehensive and efficient cleaning of unknown environments. At present, most of the cleaning robots mainly have the following problems: first, the random cleaning mode of the usual cleaning robots often misses a large number of uncleaned areas, and the cleaned areas are often cleaned repeatedly, resulting in low cleaning efficiency; second, some The new cleaning robot needs to use expensive ranging equipment such as laser radar rangefinder or laser SLAM (Simultaneous Localization And Mapping, simultaneous positioning and map construction) to map, locate and navigate in the actual working area. On the one hand, the cost of laser radar is relatively high. This increases the cost of the sweeper. On the other...

Problems solved by technology

At present, most of the cleaning robots mainly have the following problems: first, the random cleaning mode of the usual cleaning robots often misses a large number of uncleaned areas, and the cleaned areas are often cleaned repeatedly, resulting in low cleaning efficiency; second, some The new cleaning robot needs to use expensive ranging equipment such as laser radar range finder or laser SLAM (Simultaneous Localization And Mapping, synchronous positioning and map construction) to map, locate and navigate in the actual working area. On the one hand, the cost of laser radar is relatively high. This increases the cost of the sweeper. On the other hand, due to the large size of the laser radar, the use of laser radar increases the overall volume and weight of the equipment
