SBIR Phase I: Precise Magnetic Tracking of Robotic/Virtual Reality Systems

马修斯 这个小型企业创新研究第一阶段项目将开发一种新型的磁传感技术，可用于各种机器人和虚拟现实操作，以非常高的精度感测局部位置精度。通过将廉价的磁阻传感器阵列固定到附近的参考表面，并将小型发射线圈连接到移动部件，可以非常准确地跟踪，监控和存储机器人（或人类）的动作，以供将来审查。可以独立地测量每个发射线圈相对于参考表面的位置和取向，其中预期的位置精度为约1毫米，旋转精度优于一度。第一阶段的工作将是建立一个原型系统，以进一步确定这种系统的操作参数和预期性能。 商业应用包括机器人控制、虚拟现实、远程呈现（即，机器人技术和虚拟现实的结合），监控人类表现（例如，头部、手部动作）和训练。 在军事上，训练系统和人在回路中的目标定位应用将受益于这种低成本、强大的能力。 随着进一步的发展，检测和跟踪更大的物体，如隐藏的武器（执法需要），汽车/卡车（智能车辆/公路系统应用）和飞机超过数百米将是可能的。 ***

*** 9660797 Matthews This Small Business Innovation Research Phase I project will develop a novel magnetic sensing technique that can be used in a variety of robotic and virtual reality operations to sense local positional accuracy to a very high degree of precision. By fixing an array of inexpensive magneto-resistive sensors to a nearby reference surface and attaching small transmit coils to the moving parts, robotic (or human) actions can be very accurately tracked, monitored and stored for future review. The position and orientation of each transmit coil with respect to the reference surface can be independently measured, with an expected positional accuracy of about one millimeter and rotational accuracy of better than one degree. The Phase I effort would be directed toward building a prototype system to further define the operational parameters and expected performance of such a system. Commercial applications include robotic control, virtual reality, telepresence (i.e., the combination of robotics and virtual reality), monitoring human performance (e.g., head, hand movements), and training. In the military, training systems and man-in-the-loop targeting applications would benefit from such a low cost, robust capability. With further development, detecting and tracking of larger objects such as concealed weapons (law enforcement need), cars/trucks (Intelligent Vehicle/Highway System applications) and airplanes over hundreds of meters will be possible. ***
