This product is a smart home security protection robot. We mainly use Raspberry Pi rasperry, arduino, ESP8622wifi module, and HC05 Bluetooth module to design a smart home protection robot based on embedded Linux system, which realizes home security risk prediction, Smoke alarm, voice recognition, visual following, human-computer interaction, intelligent garbage pickup and other functions. In terms of modularity, the product is assembled into a systematic product based on various small parts. It consists of a four-wheel omni-directional chassis, a five-degree-of-freedom robotic arm, lidar, sensors (including infrared, camera, gyroscope, acceleration) And other structures. In addition, children can remotely monitor the home scene through multi-client and web browser to view the living conditions of the elderly in the room in real time. The elderly can also direct the robot to work through voice commands. In addition, the smoke alarm connected to the ESP8622wifi module can make the first call to the fire brigade in the local area and the children's mobile phone when the fire comes. This product will be based on the background of the times, through the design of physical products, analysis of a series of applications of smart home safety protection robots, and provide constructive suggestions for intelligent robots to better play their functions. Always pay attention to the safety of the elderly, let science and technology benefit mankind
