让机器人触觉传感器相互学习力感知,无需重复标定。
Training Tactile Sensors to Learn Force Sensing from Each Other
- 用共享表征统一不同传感器信号,模拟大脑触觉记忆
- 在异构传感器间实现高精度力预测,跨传感器泛化性能强
- 适合需要自适应触觉的机器人抓取与防滑场景
人类通过多指协同和体感皮层统一的触觉记忆系统,实现稳定灵巧的物体操作。受此启发,我们提出GenForce,首个实现机器人手部触觉传感器间可迁移力感知的框架。GenForce将触觉信号统一为共享标记表示,类似于皮层感觉编码,使在某一传感器上训练的力预测模型可直接迁移到其他传感器,无需重新收集大量力数据。实验表明,GenForce在同质传感器(不同配置)和异质传感器(不同传感模态与材料)间均实现良好泛化。该方法在机器人力控任务中表现优异,包括日常物品抓取、滑移检测与规避。结果证明了一种可扩展的跨传感器触觉学习范式,为非结构化环境中自适应、具触觉记忆的操纵提供了新路径。
原文摘要 · Abstract (English)
Humans achieve stable and dexterous object manipulation by coordinating grasp forces across multiple fingers and palms, facilitated by a unified tactile memory system in the somatosensory cortex. This system encodes and stores tactile experiences across skin regions, enabling the flexible reuse and transfer of touch information. Inspired by this biological capability, we present GenForce, the first framework that enables transferable force sensing across tactile sensors in robotic hands. GenForce unifies tactile signals into shared marker representations, analogous to cortical sensory encoding, allowing force prediction models trained on one sensor to be transferred to others without the need for exhaustive force data collection. We demonstrate that GenForce generalizes across both homogeneous sensors with varying configurations and heterogeneous sensors with distinct sensing modalities and material properties. This transferable force sensing is also demonstrated with high performance in robot force control including daily object grasping, slip detection and avoidance. Our results highlight a scalable paradigm for cross-sensor robotic tactile learning, offering new pathways toward adaptable and tactile memory-driven manipulation in unstructured environments.
