OpenTac: open-source tactile skins give any robot a sense of touch, from Johns Hopkins
alexcovo_eth · x · 2026-10-23
OpenTac, a new open-source tactile sensing ecosystem from Johns Hopkins, lets you design, customize and deploy piezoresistive sensor skins on any robot surface — fingers, grippers, hands, even feet. The sensors estimate both normal and shear forces to detect contact, pushing and slipping; a CAD tool converts 2D outlines or 3D models into fabrication-ready flexible PCBs and 3D-printed covers. Adaptive readout hits 1,286 partial updates per second on a 1,024-sensor array. All software, hardware and firmware are open-sourced.
