Service robot grasp guidance system and method thereof

Abstract

The invention provides a service robot grasp guidance system and a method thereof, and belongs to the technical field of robots. The system of the invention comprises an image collecting device, a radio-frequency induction receiving-transmitting device, and a vision and radio-frequency information confluence processing unit. The image collecting device is mounted at the head part of a robot. The vision and radio-frequency information confluence processing unit is mounted on the body of the robot and receives the panoramic visual information transmitted from the image collecting device and the radio-frequency information transmitted from the radio-frequency induction receiving-transmitting device. The method of the invention comprises the steps of mounting a passive radio-frequency tag; using a panoramic CCD camera to collect images and establishing a sequential all-dimensional image library; transmitting a command of fetching a specific article from a target position to the robot; realizing automatic location of the robot; and identifying a to-be-fetched article by a radio-frequency induction transceiver mounted at the gripper portion of the robot. The invention uses a panoramic vision to realize location and navigation of a mobile robot, identifies an article to be picked up by RFID, and provides sufficient information for the mobile robot to fetch articles.

Description

technical field [0001] The present invention relates to a system and a method in the technical field of robots, in particular to a service robot grasping and guiding system and a method thereof. Background technique [0002] Since the American Devol proposed the concept of industrial robots and applied for a patent in 1954, the development of robot technology has gone through three stages. The first stage of robots is a teaching and reproduction robot arm applied in a structured environment without sensing devices. , can only complete the predetermined repetitive work, and cannot perceive and respond to environmental information; the robot in the second stage is equipped with some sensors, such as force sensors, and can easily interact with the environment, but the robot does not have intelligence; the robot in the third stage The robot is equipped with a variety of sensors, such as vision sensors, laser sensors, sonar sensors, etc., and can fuse and process the information ...

Problems solved by technology

However, due to factors such as illumination changes and occlusions, the effect of vision-based object recognition in the actual application process is poor, the recognition ability is limited, and the recognition accuracy is low.
