Abstract

The invention discloses a navigation vehicle and a navigation method, aiming at solving the problem that the prior automatic navigation vehicle generally adopts two-wheel differential speed or Mecanumwheel drive, adopts magnetic strips or lasers to cooperate with bent sheet metal parts for navigation and positioning, and the positioning accuracy is poor. The utility model comprises a frame unit,a driving unit, a power unit and a control system, wherein the driving unit and the power unit are respectively connected with the frame unit. In the invention, the structure design of the upper frameand the auxiliary support frame is adopted, which is favorable for reducing the manufacturing difficulty and the production cost of the vehicle body. Based on the split design, the manufacture of thenavigation vehicle is simpler. And the upper frame can be used as the upper support part to provide better load-carrying capacity. At the same time, based on the design of the driving unit, the navigation vehicle of the invention has the ability of omni-directional movement, and has better obstacle-crossing and pit-crossing ability. In addition, based on the improvement of the positioning unit, the positioning accuracy of the present invention is improved to+ / - 5 mm, and the present invention has high application value.

Description

technical field [0001] The invention relates to the field of machinery, especially the field of automatic guided vehicles, and specifically relates to a guided vehicle and a navigation method. Background technique [0002] At present, the existing automatic guided vehicle operation modes mainly adopt the following types. [0003] The first is to lay magnetic strips on the ground, and the navigation vehicle will travel according to the path of the magnetic strips. When the positioning magnetic strip is used to precisely position the navigation vehicle, a positioning magnetic strip sensor needs to be installed on the vehicle body, and a small piece of magnetic strip should be pasted on the platform where positioning (working) is required; the navigation vehicle relies on the navigation system laid on the road The magnetic strip walks on a fixed track, and the RFID tag is used to inform the navigation vehicle whether it has arrived near the designated station, and the small ma...
