Braking to Avoid a Collision: Information, Control, and Dynamics

一个孩子跑过一扇旋转门，做了一件与落在树枝上的小鸟相同的事情。这两种情况都会产生软碰撞，而不是完全避免接触。考虑到海军飞行员降落在航母甲板的颠簸表面的情况，在尝试过程中发生剧烈变化的情况下，也可以进行软的可生存碰撞。为了了解人类和动物如何在软碰撞中取得成功，科学家们必须解释所有这些情况下的软碰撞。在国家科学基金会的支持下，Brett Fajen博士的研究旨在了解人们如何适应广泛的条件，成功地实现软碰撞，或者只是避免与运动路径中的障碍物相撞。这项研究将使用模拟器进行，在模拟器中，Fajen博士可以系统地改变任务、环境和动态约束，并观察人们如何适应这些变化。该项目的更广泛影响包括应用于交通安全、移动机器人的设计、远程遥控车辆，以及对人类视觉-运动缺陷的更深入了解。该项目通过支持伦斯勒理工学院两门新课程的开发，并为本科生和研究生提供参与研究的机会，将研究和教育结合在一起

A child who runs through a swinging door does something in common with a bird that lands on a tree branch. Both cases produce soft collisions rather than avoiding contact altogether. Soft survivable collisions can also be made in circumstances that change dramatically in the attempt, consider the circumstances of a Navy pilot landing on the bucking surface of a carrier deck. To understand how people and animals succeed in their capacity for soft collisions, scientists must account for soft collisions in all these situations. With support from the National Science Foundation, Dr. Brett Fajen's research aims at understanding how people adapt to a wide range of conditions to successfully accomplish soft collisions or simply avoid collisions with obstacles in the path of motion. The research will be conducted using a simulator in which Dr. Fajen can systematically vary the task, environmental, and dynamic constraints, and observe how people adapt to such changes. The broader impacts of this project include applications to transportation safety, the design of mobile robots, teleoperation of vehicles from remote locations, and a deeper understanding of visual-motor deficits in humans. This project integrates research and education by supporting the development of two new courses at Rensselaer Polytechnic Institute, and providing opportunities for undergraduate and graduate students to participate in research
