Automatic guiding obstacle avoidance robot trolley in modern logistics and control method thereof

Abstract

The invention relates to an automatic guiding obstacle avoidance robot trolley in modern logistics. The trolley comprises a robot trolley body; an ultrasonic detecting device is installed on the robottrolley body and comprises a plurality of ultrasonic sensors, and each ultrasonic sensor is electrically connected with a fuzzy controller; a controller is installed on the robot trolley body and electrically connected with the ultrasonic sensors through a wireless transceiver module separately, and the controller is electrically connected with the fuzzy controllers separately; the controller iselectrically connected with servo motors on wheels of the robot trolley body through double H bridge drivers separately; an encoder is connected with all the servo motors; an orthogonal pulse decoderis connected with the encoder and the controller separately; a power monitoring reset is installed at the top of the trolley body. The travel distance of the trolley can be shortened, and therefore the travel time is shortened; the designed fuzzy controllers can improve the stability of a system and reduce errors. By using the ultrasonic sensors, obtained external information is high in accuracy,and the trolley is easy to implement.

Description

technical field [0001] The invention belongs to the technical field of logistics equipment, and in particular relates to a robot trolley for automatic guidance and obstacle avoidance in modern logistics and a control method thereof. Background technique [0002] The logistics industry has the characteristics of a large amount of work, a large amount of information, and many work links. The traditional logistics mainly relies on manual operations. In the process of sorting, loading, unloading, and transportation, it is not only inefficient, but also prone to errors. The emergence of intelligent logistics vehicles not only saves a lot of labor, but also reduces the error rate and greatly improves work efficiency. Smart car is a comprehensive multi-disciplinary and high-tech product. It not only needs to have the ability to perceive the external environment, but also needs to have the ability to plan tasks and implement decisions. Today, with the advancement of technology, sma...
