Abstract
In order to meet the mobile robot’s accuracy and speed requirements in processing obstacle information based on the study of the principle of ultrasonic and infrared distance measurement, the ultrasonic infrared measurements system is designed using Mega16L microcontroller. The hardware of the system, data fusion and software components were studied. Bayes estimation for the data fusion, which can greatly improve the measurement accuracy, was used. The human-computer interface and back panel algorithm were developed with the development language of LabVIEW. Experimental results show that the measurement error of the combined measurement system is in ± 1mm between 0 ~ 300cm, which can meet the design requirements and flexible operation.
