项目摘要

This Smart Health (SCH) award will contribute to the advancement of the national health and welfare by developing technology to help the millions of people who have suffered an amputation or who have a congenital deficiency of an upper limb. These problems create a devastating impact on the quality of the victims’ lives and pose a significant financial burden to people in the U.S.A. Unfortunately, the state of the art in prosthetic hand replacements is not comparable to their popular portrayal in sci-fi movies, leaving upper limb-absent people with rudimentary control of basic grasp functions. This work will explore methods to help upper limb-absent people learn advanced control of sophisticated prosthetic hands with an automated training regimen that can be used at home. Automating this aspect of healthcare with remote learning functionality can help disabled people access treatment more quickly and at a lower cost. Furthermore, research from this grant will be used to create learning experiences for high school students from low-income households to help educate the next generation of engineers and scientists. Thus, this research can benefit the society and economy of the USA. Currently, there are numerous options for dexterous wearable co-robot assistants, such as prosthetic hands, with future devices becoming even more sophisticated. In fact, the dexterity of these devices is rapidly outpacing the ability for people to intuitively control them. One main source of this problem stems from the inability to reliably interpret the intentions of the human operator over the course of months and years. Another problem is that the science behind customizable training programs to empower disabled people to harness the full potential of dexterous assistive robots such as prosthetic hands has not been deeply explored. This project will address these deficiencies through three main endeavors: (1) exploration of a novel bimodal skin sensor to overcome limitations with current sensors, (2) investigation of the utility of machine learning algorithms to classify the intention of human operators, and (3) creation of a new reinforcement learning paradigm to sequentially introduce customized, subject-specific muscle training exercises over time to maximize biocontrol signal classification accuracy and the number of independent biocontrol channels.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个智能健康奖将通过开发技术来帮助数百万遭受截肢或上肢先天缺陷的人，为提高国家健康和福利做出贡献。这些问题对受害者的生活质量造成了毁灭性的影响，并给美国人民带来了巨大的经济负担。不幸的是，目前的假肢置换技术还不能与科幻电影中流行的形象相提并论，让上肢缺失的人只能掌握基本的抓握功能。这项工作将探索方法，帮助上肢缺失的人学习先进的控制复杂的假肢手与自动化的训练方案，可以在家里使用。使用远程学习功能自动化医疗保健的这一方面可以帮助残疾人以更低的成本更快地获得治疗。此外，这笔拨款的研究将用于为低收入家庭的高中生创造学习经验，以帮助培养下一代工程师和科学家。因此，这项研究对美国的社会和经济都是有益的。目前，灵巧的可穿戴协作机器人助手有很多选择，比如假肢手，未来的设备将变得更加复杂。事实上，这些设备的灵巧性正迅速超过人们凭直觉控制它们的能力。这个问题的一个主要原因是无法可靠地解释人工操作员在数月或数年的过程中的意图。另一个问题是，可定制的培训计划背后的科学，使残疾人能够充分利用灵巧辅助机器人（如假肢手）的潜力，尚未得到深入探索。本项目将通过三个主要努力来解决这些不足：(1)探索一种新的双峰皮肤传感器，以克服现有传感器的局限性；(2)研究机器学习算法的实用性，以对人类操作员的意图进行分类；(3)创建一种新的强化学习范式，以便随着时间的推移，依次引入定制的、特定主题的肌肉训练练习，以最大限度地提高生物控制信号的分类精度和独立生物控制通道的数量。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
