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 ...

It is designed to navigate disaster-struck areas, detect humans using thermal imaging, determine motion using PIR sensors, and report precise GPS coordinates via GSM-based SMS alerts. The system ...

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.
