Intelligent indoor positioning water supply systembased on Internet of Things

With the development of the Internet of Things technology, robots have been widely used in production and life. As an intelligent drinking water system, the automatic water supply robot can be applied to various places such as office areas, hospitals, homes, etc., to intelligently provide drinking water services for human beings. This article has designed a smart indoor positioning water supply system, which can realize the functions of cup positioning, steering forward, and automatic water filling. The system uses the UP Squared processor as a design platform, and expands functional modules such as UWB positioning, Zigbee wireless transmission, gyroscope, and robotic arm. The MPU6050 module is used to sense the rotation angle, and the PID algorithm controls the robot"s rotation. The current cup position is detected based on the current magnetic effect and the law of electromagnetic induction. The ultrasonic module is used to detect the height of the water outlet and the water level in the cup. Several parameters such as the positioning, direction adjustment, ranging, power consumption, and water delivery process of the system were tested through experiments. The results show that the system has the characteristics of accurate positioning, fast and stable steering, and low power consumption, and has been applied to indoor intelligent positioning Technical requirements for water delivery.
