Embodiment Construction

[0055] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0056] The purpose of the present invention is to provide a kind of robot and its control method. In terms of perception, it is divided into the perception of robot posture and position, and the control aspect is mainly to control the robot posture and position, and accurately perceive the robot through this method. The position and attitude of the robot can be achieved to achieve high-precision linear and rotational movement of the r...

Abstract

The invention relates to a duct cable robot and a control method thereof. The control method comprises the following steps: establishing a mapping relation among a camera coordinate system, an inertial coordinate system and a world coordinate system; obtaining a current frame movement distance and a current frame rotation matrix based on the current frame pipeline image and the previous frame pipeline image, and obtaining a current frame movement speed based on the current frame movement distance and the shooting period; judging the pipeline image of the current frame, and if no obstacle exists, obtaining the world coordinate position of the current frame based on the moving distance of the current frame and the mapping relation; controlling the robot to move linearly based on the current frame world coordinate position, the current frame moving speed, the given position and the given speed; if the obstacle exists, obtaining the moving speed of the current frame based on the moving distance of the current frame and the shooting period; and controlling the robot to rotate based on the current frame rotation matrix, the current frame movement speed, the given attitude angle and the given speed. According to the invention, the robot is controlled to complete linear and rotary motion with high precision.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a pipe-arranging cable robot and a control method thereof. Background technique [0002] With the rapid development of power scale, the construction scale of power grid system is getting larger and larger, and the rapid growth of urban electricity load has put forward higher and higher requirements for the reliability of power supply. The power grid system is easily affected by various influence of factors. [0003] The use of underground cables to replace overhead transmission lines is one of the best transmission and distribution methods in cities with densely populated areas. The underground cable channels can accommodate multiple circuits, and the adaptability of transmission capacity is enhanced, avoiding lightning, wind and rain, and salt fog. The influence of natural environment such as pollution and pollution on the cable improves the reliability of power supply. However...
