FlexiTac: Open-Source Tactile Sensor for Robots
FlexiTac presents an affordable, open-source solution for piezoresistive tactile sensing in robotic end-effectors, as outlined in arXiv:2604.28156. This system features flexible sensor pads alongside a compact multi-channel readout board that transmits synchronized data at a rate of 100 Hz, enabling real-time control and extensive data collection. The sensor pads consist of a sealed three-layer laminate structure (FPC-Velostat-FPC) with integrated electrode designs, enhancing production efficiency and consistency while ensuring adaptability for both rigid and soft grippers. The readout electronics utilize commonly accessible, economical components. Available configurations include fingertip pads and larger tactile mats.
