FlexiTac is a piezoresistive tactile sensor developed and open-sourced by Columbia University's Yunzhu Li team, showcased at IROS 2026. The sensor aims to strike a balance between flexibility, low cost, and consistency, providing robots with reliable tactile input.
Tactile perception remains a weak link in embodied intelligence systems. In fine manipulation scenarios, when objects are occluded, transparent, or fragile, vision alone struggles to determine whether a robot has a secure grip or whether slippage has occurred, and cannot achieve reliable force control or compliant interaction. Tactile data is indispensable for such tasks.
Unlike the vision field, which has formed a relatively unified sensor and data ecosystem, tactile research has not yet converged. Different laboratories use different types of sensors, but they commonly face the challenge of simultaneously balancing lifespan, flexibility, multi-dimensional information perception, resolution, cost, and consistency, making it difficult to scale data collection and algorithm research.
FlexiTac's open-source practice provides a reproducible hardware solution for tactile perception, helping to lower the research barrier and promote tactile data standardization and algorithm research. If tactile perception can be scaled like vision, it will significantly enhance robots' manipulation capabilities in complex physical environments, holding foundational significance for the deployment of embodied intelligence.
