Problems solved by technology

However, the current automatic guided vehicles still have the following deficiencies: 1. The driving mode is single, and the deviation of the walking route is large, so that precise control cannot be achieved; 2. The steering control is not flexible, and the in-situ steering cannot be realized; The barrier function is poor; 4. It is inconvenient to adjust the height when transporting tooling vehicles with different height requirements

Embodiment Construction

[0014] In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the related drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that a thorough and complete understanding of the present disclosure is provided. It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "front," "rear," "parallel," and similar expressions used herein are for illustrative purposes only and do not represent the only em...

Abstract

The invention discloses an automatic guided vehicle comprising a vehicle body, a differential control device, a navigation control device, a steering control device, an obstacle avoidance device, a liftable climbing mechanism, a power supply device, and a main control device. According to the invention, the differential control device employs a two-wheel independent driving way and controls steering and drive steering based on the differential value; and with cooperation of the navigation control device, crooked moving of the vehicle body is prevented. An electronic gyroscope of the steering control device collects an azimuth signal of the vehicle body and outputs the azimuth signal to the main control device for processing. The main control device outputs an instruction to control the differential control device to make motion, thereby realizing pivot steering of the vehicle body. When the vehicle walks, a collision avoidance distance is set; and with a range finding sensor of the obstacle avoidance device, adjustable detection of the free distance can be realized, so that safety driving of the vehicle can be guaranteed. The liftable climbing mechanism employs a stepping motor to realize precise position adjustment of the lifting mechanism, so that full-range precise height adjustment is realized during carrying of tooling vehicles with different height requirements can be realized.

Description

technical field [0001] The invention relates to an automatic guided transport device, in particular to an automatic guided trolley. Background technique [0002] With the gradual development of factory automation and computer integrated manufacturing system technology and the wide application of flexible manufacturing systems and automated three-dimensional warehouses, automatic guided vehicles (AGVs) are the necessary automation to connect and adjust discrete logistics systems to make their operations continuous. Handling and loading and unloading means, its application range and technical level have been developed rapidly. However, the current automatic guided car still has the following shortcomings: first, the driving mode is single, the deviation of the walking route is large, and the precise control cannot be achieved; second, the steering control is inflexible, and the in-situ steering cannot be realized; third, the safety is not good, avoid The barrier function is p...
