Industrial safety laser simultaneous localization and mapping (SLAM) navigation pallet stacking automated guided vehicle (AGV)

Abstract

The invention relates to an automated guided vehicle (AGV) trolley, in particular to an industrial safety laser simultaneous localization and mapping (SLAM) navigation pallet stacking AGV. The industrial safety laser SLAM navigation pallet stacking AGV includes a frame, a lower covering part fixed to the front end of the frame, an upper covering part fixed between the top of the frame and the topof the lower covering part, a laser SLAM navigation system and a vehicle driving system, a vehicle controller is arranged inside the lower covering part, a fork mechanism is arranged at the rear of the frame, the fork mechanism is driven by a fork lifting system, the fork lifting system includes a pumping station, a lifting cylinder and a driving chain, and an obstacle avoidance system is furtherincluded. The obstacle avoidance system includes a front obstacle avoidance unit, a rear obstacle avoidance unit and a safety relay component connected between a vehicle power supply and the vehicle driving system. The front obstacle avoidance unit includes a laser obstacle avoidance module arranged at the bottom of the lower covering part and a safety edge contact module arranged at the bottom ofthe lower covering part. The technical scheme can overcome the defects of the low AGV parking accuracy and ineffectiveness in obstacle avoidance function in the prior art.

Description

technical field [0001] The invention relates to an AGV trolley, in particular to an industrial safe laser SLAM navigation pallet stacking type AGV. Background technique [0002] SLAM (Simultaneous Localization and Mapping, real-time positioning and map construction) navigation method is a widely used real-time positioning and navigation method in the field of robots. The data adjusts the robot's travel route in real time. In the traditional factory operating environment, the transportation of objects between the automatic warehouse and the production workshop, between each station, and between each conveying line mainly relies on manpower, which has the defects of low transportation efficiency, high labor intensity, and high labor cost. Causing safety accidents is not conducive to the long-term development of enterprises. [0003] In recent years, with the development of science and technology, automation technology has shown a trend of accelerated development, and domesti...

Problems solved by technology

[0004] The existing AGV commonly used navigation methods mainly use magnetic navigation, two-dimensional code navigation, ribbon navigation and laser anti-navigation. Magnetic navigation, two-dimensional code navigation, and ribbon navigation have high requirements for the environment in which AGVs operate. Oil pollution will affect the operation of AGV. At the same time, magnetic navigation, two-dimensional code navigation, and ribbon navigation need regular maintenance, and the cost is high

The accuracy of laser reflector navigation is high, but it needs repeated position positioning in the early stage, which leads to long construction period and high cost
