A service robot that can autonomously locate and navigate between multiple floors is designed to address the issues of cross floor autonomous navigation for service robots. LiDAR( LightLaser Detection and Ranging) and SLAM ( Simultaneous Localization and Mapping ) mapping technology to achieve autonomous positioning and navigation on flat floors, and Lora robot elevator wireless communication technology is used to switch floors. Aiming at the problem of weak expansion ability of the service robot, the software and hardware interfaces are designed and equipped with execution devices such as disinfection and sterilization boxes, express cabinets, strapping machines, etc. , which complete a variety of tasks and have strong compatibility. The overall functionality of the system has been designed and optimized, and the robot has high usability and practical value.Tests have shown that the robot can achieve autonomous movement across floors and has the ability to complete diverse tasks, with good market prospects.
