Abstract

The invention discloses a sweeping path planning navigation algorithm applied to a sweeping robot with a low-cost chip. The algorithm is characterized by comprising a control layer and an algorithm layer, and comprises the following steps of: 1, the sweeping robot is started; 2, the control layer of the sweeping robot initializes a plan module in the algorithm layer, the algorithm layer returns avalue of the plan module to a pathPlan structural body in the control layer, and the pathPlan structural body is stored; 3, the sweeping robot enters a bow sweeping mode; 4, a current coordinate is calculated, whether the sweeping robot is collided is detected, an advancing mode of the algorithm layer is acquired according to a detection result, and Action is returned; 5, the Action is led into the control layer, and edge or along-line control is used according to the method; and 6, the sweeping robot judges whether sweeping is finished, and if NOT, the step 4 is returned to.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a cleaning path planning and navigation algorithm for a sweeping robot applied to a low-cost chip. Background technique [0002] With the continuous development and progress of science and technology, more and more people start to use sweeping robots. When sweeping robots are cleaning, they need to plan a cleaning path to avoid collisions with obstacles in the working area. Currently, sweeping robots are used The cleaning path planning method has the following defects: high cost, the current technology needs to store the map and consumes a lot of memory, and must use a chip above 512kb, resulting in a high cost of computing equipment; the sweeping robot needs to explore the workspace in advance to build a map before starting For cleaning tasks, it takes a long time to explore when cleaning a large space; the cleaning path planning algorithms currently applied to low-cost chips are...
