Infrared sensor-based tour guide service robot design

With the liberalization of the epidemic and the gradual recovery of the tourism sector, the profession of tour guide has become increasingly critical. However, this profession is mainly engaged in repetitive work, not very innovative. Combined with the above characteristics, in order to comply with the trend of social automation development, the tour guide service robot was born. The multi-functional intelligent tour guide service robot system takes the Raspberry Pi 4B microcomputer as the control core, completes the robot tour function through the signals collected by the infrared sensor tour module, and realizes the robot's trajectory navigation function by combining with the TB6612FNG module to drive the DC motors to arrive at a certain attraction accurately. When it arrives at a specific attraction, it will explain the relevant information of the attraction to the tourists through the voice module. In addition, the ultrasonic obstacle avoidance module with servo gimbal can avoid the obstacles that may appear on the path and adjust the route to fulfill the obstacle avoidance function.
