This project demonstrates an Arduino-based Human Following Robot using IR sensors and an ultrasonic sensor. The robot detects a human presence in front of it and follows smoothly while correcting its ...

The Time of Flight (ToF) sensor is significantly more accurate than the ultrasonic sensor. This is evident through the data shown above. Although the measurements were generally smaller than realistic ...

Abstract: An optical fiber ultrasonic coupling sensor enhanced by a resonant cavity is design and optimization in this work. By using the prestressed bonding method, the structure consists of optical ...

Abstract: The stress field of steel members in service is unevenly distributed under complicated loads. The existing single-path ultrasonic (SPU) sensors can only measure stress in a single ...
