Collaborative Research: Dextrous Control of Multi-Digit Grasping

人类手的复杂性需要创造性和多学科的努力，以了解它的控制。大脑依靠各种策略来简化对复杂动作的控制，比如手产生的动作。然而，大多数对这些策略的研究都集中在有限的任务上，这些任务可能不会概括为自然的抓取行为，也没有考虑到感觉的使用。这项合作研究计划的总体目标是测试抓取策略如何依赖于所执行的行为。这些结果将为我们深入了解大脑如何控制和协调手的复杂结构，以及感觉信息如何在这种控制中使用。这个项目的结果具有潜在的变革性，因为了解手是如何控制的，以及大脑如何控制复杂的运动具有广泛的应用前景。考虑到手在我们的运动行为中扮演的关键角色，从艺术表达到工具使用，结果可能会影响几个领域，包括神经科学、机器人操作(例如，太空探索、远程操作手术)和智能假肢的发展。此外，这些项目还将营造丰富的学习环境，促进研究和教育的融合。

The complexity of the human hand requires creative and multidisciplinary efforts aimed at understanding its control. The brain relies on strategies to simplify the control of complex movements such as those produced by the hands. However, most studies of these strategies have focused on limited tasks that may not generalize to natural grasping behaviors and that do not take into account the use of sensation. The overall aim of this collaborative research proposal is to test how grasp strategies depend on the behavior performed. The results will provide insight into how the brain controls and coordinates the complex architecture of the hand and how sensory information is used in this control. The results of this project are potentially transformative in that understanding how the hand is controlled as well as how the brain controls complex movements has a wide variety of applications. Given the key role that the hand plays in our motor behavior, ranging from artistic expression to tool use, results may influence several fields, including neuroscience, robotic manipulation (e.g., space exploration, tele-operated surgery) and the development of 'smart' prosthetics. Furthermore, the projects will foster a rich learning environment for integrating research and education.
