Design of Biological Tank AGV Gripper Based on QR Code Guidance
Biological tank AGV is a robot applied in unmanned storage and transportation of low-temperature cold storage in medical institutions.In order to improve its low positioning accuracy and low recognition ability,shorten its long transportation cycle and simplify its redundant gripper mechanism,a gripper based on laser navigation and QR code navigation is designed with optimization design in terms of control and structure.In the aspect of cotrol,the region is normalized through the change matrix and calibrated by HMD calibration method,and ositioning method is switched between laser navigation and QR code navigation according to the environmental changes.Structurally,the ECRS principle and variable density method are introduced to build the model by SolidWorks three-dimensional software,and the finite element analysis on the core components of the gripper is carried out under the limited conditions of material and load by SolidWorks analysis unit.The test results show that the designed gripper shortens operation cycle,improves grasping accuracy,simplifies grasping mechanism,and has good economic value.
