Enabling Tactile Feedback in Robotic Manipulation via FBG Sensors and Haptic Interfaces

Description

The sense of touch is essential for dexterous and safe robotic object manipulation. The same holds in teleoperation, where a major challenge is still how to deliver intuitive tactile feedback from the robot to the human operator. This work presents a wireless, real-time system that integrates an array of Fiber Bragg Grating tactile sensors in a custom robotic gripper, with a wearable haptic interface. Multiple sensor signals were combined and transformed into intuitive force feedback, allowing a remote user to perceive manipulation interactions of the robot with an object in a quasi-natural manner.
