Embodiment 1

[0046] This embodiment provides a method for a robot to grab an item, the method comprising:

[0047] Step S101: Obtaining the first position of the robot and the second position of the item, wherein the first position and the second position come from a Kinect infrared device;

[0048] Step S102: According to the first position and the second position, obtain a first movement trajectory from the robot to the object;

[0049] Step S103: Obtain a target position according to the first movement trajectory, so that the robot moves to the target position to grab the object.

[0050]In the above method, obtain the first position of the robot and the second position of the article by the Kinect infrared device, and send the above-mentioned first position and the second position to the robot, and establish a data connection between the Kinect infrared device and the robot, and can For interaction, Kinect infrared device acquisition can obtain accurate location information, which can...

Embodiment 2

[0077] Based on the same inventive concept as in Embodiment 1, Embodiment 2 of the present invention also provides a method for a robot to grab an item from the perspective of a Kinect infrared device, the method comprising:

[0078] Step S201: the Kinect infrared device acquires the first position of the robot and the second position of the item;

[0079] Step S202: Sending the first position and the second position to the robot, so that the robot obtains a target position according to the first position and the second position so as to grab the object.

[0080] Specifically, in the method for grabbing an item provided in an embodiment of the present invention, the Kinect infrared device acquires the first position of the robot and the second position of the item, including:

[0081] Obtain a spatial depth image;

[0082] Obtain pixel coordinates and depth coordinates according to the spatial depth image;

[0083] Obtain the first position of the robot and the second positi...

Abstract

The invention discloses an object grabbing method of a robot. The method includes the steps that a first position of the robot and a second position of an object are obtained, wherein the first position and the second position come from Kinect infrared equipment; a first motion trail from the robot to the object is obtained according to the first position and the second position; and a target position is obtained according to the first motion trail so that the robot can move to the target position to grab the object. By means of the object grabbing method, the object positioning accuracy is achieved, and therefore the beneficial effects of grabbing the object more accurately and enlarging the using scene and scope of the robot are achieved, and the technical problems that in the prior art, a method for positioning by using self vision of the robot is low in positioning accuracy and not suitable for the environment with dark light are solved.

Description

technical field [0001] The invention relates to the technical field of intelligent service robots, in particular to a method for a robot to grab objects. Background technique [0002] With the development of artificial intelligence technology, intelligent service robots are widely used in various home services. In a smart home environment, robots can receive instructions from people to grab and deliver needed items. [0003] In the prior art, the method of using a robot to grab an item generally uses a camera on the robot body or an external camera to locate the item, so as to realize the grabbing of the item. [0004] When the inventor of the present application realized the technical solution of the present invention, he found that at least the following problems existed in the prior art: [0005] The existing method of locating objects through the camera of the robot body has relatively high requirements for light, and is only suitable for daytime or places with suitable...
