摘要:

通过触觉反馈感知物体滑动的能力使人类能够完成复杂的操作任务,包括保持稳定的抓握。尽管触觉信息在许多应用中具有实用性,但触觉传感器尚未在工业机器人环境中广泛部署;部分挑战在于从触觉数据流中识别滑动和其他事件。在本文中,我们提出了一种基于学习的方法来检测滑动使用气压触觉传感器。这些传感器具有许多理想的特性,包括高耐用性和可靠性,并且由廉价的现成组件制成。我们训练时间卷积神经网络来检测滑动,实现了高检测精度,同时显示鲁棒性的速度和方向的滑动运动。此外,我们在涉及各种常见对象的两个操作任务上测试了我们的检测器,并成功地将其推广到训练过程中看不到的真实场景。我们认为,气压触觉感知技术,结合数据驱动的学习,适用于许多操作任务,如滑移补偿。

英文摘要:

The ability to perceive object slip via tactile feedback enables humans to accomplish complex manipulation tasks including maintaining a stable grasp. Despite the utility of tactile information for many applications, tactile sensors have yet to be widely deployed in industrial robotics settings; part of the challenge lies in identifying slip and other events from the tactile data stream. In this paper, we present a learning-based method to detect slip using barometric tactile sensors. These sensors have many desirable properties including high durability and reliability, and are built from inexpensive, off-the-shelf components. We train a temporal convolution neural network to detect slip, achieving high detection accuracies while displaying robustness to the speed and direction of the slip motion. Further, we test our detector on two manipulation tasks involving a variety of common objects and demonstrate successful generalization to real-world scenarios not seen during training. We argue that barometric tactile sensing technology, combined with data-driven learning, is suitable for many manipulation tasks such as slip compensation.
