Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of shuttle vehicle, concretely relates to a servo control positioning shuttle vehicle. BACKGROUND

[0002] The shuttle vehicle is an intelligent robot, mainly used for executing picking, carrying, placing and other tasks, and can communicate with the upper computer or WMS system. The shuttle vehicle combines RFID, barcode and other identification technologies to realize automatic identification, access and other functions. The shuttle vehicle has wide application in the logistics system, has the characteristics of fast speed, high reliability and low cost, and is mainly used for material conveying, workshop assembly and the like;

[0003] The working principle of the shuttle vehicle is to realize the picking, carrying and placing of goods through programming, and to complete the conveying of the goods unit through the reciprocating motion on the track.
