Medical patrol robot with logistics function and delivery method thereof

The invention discloses a medical patrol robot with a logistics function and a delivery method thereof. The robot comprises a moving chassis and a multi-layer frame body on the upper portion of the moving chassis. A code scanning module mounting table is arranged at the upper part of the multi-layer frame body, and a screw rod slide rail assembly and a vital sign detection module are mounted on the code scanning module mounting table; a conveying belt is installed on the lead screw sliding rail assembly. And a storage box is arranged on the conveying belt. A Raspberry Pi, a lower computer control panel, a first single-chip microcomputer, a second single-chip microcomputer and a third single-chip microcomputer are further arranged on the multi-layer frame body; information interaction is carried out between the Raspberry Pi and the single-chip microcomputer, mapping is carried out based on the SLAM algorithm of Kalman filtering, an advancing route and autonomous navigation are selected, and the Raspberry Pi is
