Mobile robot and path planning method thereof for manipulating target objects

Abstract

The invention provides a mobile robot and a path planning method thereof for manipulating target objects The mobile robot and a path planning method are provided for the mobile robot to manipulate the target objects in a space, wherein the space consists of a periphery area and a central area. With the present method, an initial position is defined and the mobile robot is controlled to move within the periphery area from the initial position. Next, the latest image is captured when the mobile robot moves, and a manipulating order is arranged according to the distances estimated between the mobile robot and each of target objects in the image. The mobile robot is controlled to move and perform a manipulating action on each of the target object in the image according to the manipulating order. The steps of obtaining the image, planning the manipulating order, and controlling the mobile robot to perform the manipulating action are repeated until the mobile robot returns to the initial position.

Description

technical field [0001] The present invention relates to a method for controlling the movement of a robot, and in particular to a method for effectively planning a moving path of a robot and a mobile robot for realizing the method. Background technique [0002] The advancement of science and technology has made the research and development of various intelligent robots increasingly vigorous; among them, entertainment robots such as electronic pets can meet the needs of modern people who want to keep pets in their spare time, and the types are more extensive. In addition to the application of assistant robots in medical treatment, security, instrument operation, education, and even disaster relief, assistant robots related to general life needs are becoming more and more popular and valued by modern people. [0003] Taking the indoor cleaning robot as an example, the indoor cleaning robot can automatically walk in the room and perform the function of collecting garbage while w...

Problems solved by technology

However, when most assistant robots perform their functions in a space, they will walk blindly in the space until they collide with obstacles before changing their direction of travel.

In other words, this type of robot not only cannot automatically avoid obstacles, but also has to wait until it encounters a target to perform processing actions due to blind walking. Such passive processing will inevitably consume more power and make the efficiency of completing work relatively low. ; Another kind of robot will move in space according to a fixed preset path, just like walking around the room continuously in the way of going back and forth

The fixed path makes the robot's movements less flexible, and in the case of some areas that are difficult to reach, some areas may be repeated many times

It can be seen that whether it is walking blindly or following a fixed preset path, it is difficult to improve the efficiency of the robot's work without path planning for the target.
