Implementing Tactile and Proximity Sensing for Crack Detection [PDF]

2020 IEEE International Conference on Robotics and Automation (ICRA), 2020
Remote characterisation of the environment during physical robot-environment interaction is an important task commonly accomplished in telerobotics. This paper demonstrates how tactile and proximity sensing can be efficiently used to perform automatic crack detection. A custom-designed integrated tactile and proximity sensor is implemented. It measures
