To address problems of logistic robots, including the difficulty in positioning and posturing, poor interaction, monotony of tasks (carry and capture), etc., an intelligent logistic robot is designed. The robot is assigned with a task from the server via DT-06WIFI or through QR code scanning at Openmv and then informed of the position of the object by identifying bar code. The robot is arranged with a CN-TTS voice module and OLED display for reporting the robot's exceptional information and showing its normal information respectively. The robot enables capture in three dimensions based on parallel four-link mechanism and multi-link mechanism and adopts modified dual-loop (angle and speed) serial algorithm and chassis control strategy of kinematic resolution module. Through actual tests, the design scheme can realize a series of logistics handling tasks such as positioning, walking, recognition and grasp, etc. The design of Multi-sensor fusion make the robot applicable to a broader range of scenarios and can carry out tasks as required with much better human-machine interaction.
