Abstract: In this study, we propose an ultrasonic tactile sensor for real time contact force measurements and high-resolution shape recognition to enable safe and reliable robotic grasping of objects ...

The project integrates an STM32 microcontroller for control and motion and an ESP32 for sensor fusion, communication, and high-level decision-making.

This embedded project measures distance using an ultrasonic sensor and displays the result on an LCD. When a valid distance is detected, the system controls a stepper motor to rotate in a clockwise ...

A pocket-size ultrasonic bladder-volume sensor has been constructed and tested with successful results. This paper describes the sensor and presents results from its use on healthy volunteers.
