Method and system for eliminating motion deviation and automated guided vehicle

Abstract

The invention discloses a method and a system for eliminating motion deviation and an automated guided vehicle, and relates to the technical field of computers. One specific embodiment of the method comprises the following steps: determining the current residual exercise amount of the exercise device under the condition of receiving a limiting signal, wherein the limiting signal is recognized based on a limiting assembly arranged on the moving device; judging whether the current residual exercise amount is smaller than a preset judgment threshold value or not; if not, generating a first motioninstruction according to the current residual motion amount, so that the motion device continues to move according to the first motion instruction; if so, changing the current residual motion amountinto a deviation rectifying motion amount, and generating a second motion instruction according to the changed current residual motion amount, so that the motion device stops at the target position according to the second motion instruction, wherein the deviation rectifying movement amount is the minimum distance between the limiting assembly and the target position. The method can detect whetherthe motion deviation exists or not in real time according to the arrangement of the limiting assembly, and effectively eliminates the motion deviation.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method, system and automatic guided transport vehicle for eliminating motion deviation. Background technique [0002] When the motion device performs linear motion or rotary motion, some small errors will occur, and the accumulation of multiple errors will constitute a motion deviation. For example, the automatic guided transport vehicle AGV, the entire mechanical mechanism of the AGV is divided into a chassis structure and a tray structure. Generally, the chassis structure uses two servo motors to drive the differential gear train, and the tray structure is driven by a servo motor. During the process of moving the shelves, the chassis structure and the pallet structure will have a synchronous rotation and a separate rotation of the pallet structure. Since there is no positioning means for the relative position between the chassis structure and the tray structure, a position...

Problems solved by technology

[0004] The existing elimination of motion deviation generally requires manual adjustments on a regular basis

This method not only has the problem of low operating efficiency, but also may cause movement errors if the movement deviation is not eliminated in time
