The invention provides a robot with intelligent follow-up function, comprising a display screen module, a camera module, a drive module, an ultrasonic ranging module and a mobile robot; the display screen module, the camera module, the drive module and the ultrasonic ranging module are arranged respectively on the ARM development board; the ARM development board is mounted on the mobile robot; the display screen module and the camera module are mounted at a head of the mobile robot and used to recognize a target object. The ultrasonic ranging module is mounted right below the camera module and the display screen. The robot has the advantages that the robot is scientific and reasonable in design, humanized and low in cost; the robot can turn 2360 degrees and follow up by searching for a target; the robot may be used in intelligent follow-up for walking function products such as household accompanying products, intelligent trolley cases, intelligent baby carriers and intelligent seats; the robot using ultrasonic ranging technology is insusceptible to external signals and is high in measuring precision.
