IEEET-ASE|基于视触觉传感器的柔性接触仿真与操作学习
机器人大讲堂· 2025-06-30 07:22
近期北京邮电大学方斌教授团队联合清华大学、 意大利比萨圣安娜大学、英国伦敦国王学院和德国汉堡大学 发布了基于掌状视触觉传感器的柔性接触仿真与操作学习,为基于视触觉传感器的柔性操作提供了新的思路。 相关工作发表在机器人、自动化领域 JCR Q1 期刊 IEEE Transactions on Automation Science and Engineering 。 研究背景: 可变形物体操控是机器人领域一个经典且极具挑战性的任务。相较于刚性物体,可变性物体具复杂的变形特性 (包括弹性变形、塑性变形和弹塑性变形),大量的自由度 (DOF) 需要复杂的建模方法,这使该问题更加复 杂。同时,可变形物体广泛存在于医院、工业和家庭环境中。因此,可变形物体操控在机器人技术发展中发挥 着至关重要的作用。 为此,本文开发了一款可变形物体与基于视觉的触觉传感器之间的软接触模拟器,该模拟器能够模拟视触觉传 感器与弹性、塑性以及弹塑性物体之间的接触变形。在此模拟器的基础上,本文提出了基于视触觉传感器的可 变形物体操控基准,包括可迁移的观测值、任务和专家演示系统。最后,本文搭建了相应的实验平台,完成了 相关任务的 Sim-to-rea ...

Core Idea - The article discusses the educational philosophy of Grundtvig, a significant Danish thinker who advocated for universal education and lifelong learning, breaking the monopoly of the elite on education and laying the foundation for Denmark's public education system [1][2][3]. Group 1: Grundtvig's Philosophy and Impact - Grundtvig's philosophy emphasizes that education should be accessible to everyone, regardless of their social status, and focuses on awakening the human spirit rather than merely imparting knowledge [2][3]. - He believed that the enlightenment of the populace was essential for national strength and advocated for fundamental reforms in education, establishing adult schools for farmers, workers, and ordinary citizens [2][3]. - Grundtvig founded Denmark's first adult school in 1844, promoting an open educational model where students could choose courses based on their interests, fostering lifelong learning and cultural enrichment [3]. Group 2: Development of Adult Education in Denmark - Under Grundtvig's influence, adult schools proliferated in Denmark, significantly enhancing the cultural quality and economic development of the populace [3]. - The cooperative movement in agriculture, inspired by the education provided in these adult schools, improved product quality and market resilience, contributing to Denmark's modern agricultural success [3]. - Today, Denmark has approximately 70 adult schools, which are integral to the national education system, with a literacy rate of 99% and a higher education enrollment rate of 85% [3].
