Autonomous robotic vehicles, ground or aerial, play critical roles in various intelligent operations seen or desired in our current and future lives, ranging from home services and industrial manufacturing, to more and more field applications such as natural resource monitoring, pipeline and building inspection, precision agriculture, mineral exploration, search and rescue operations, etc. Due to the increasing complexity in functioning expectation, there is no doubt that networked and collaborative operation of autonomous robotic vehicles will be in high demand. It is well known that one of the biggest challenges facing autonomous vehicles is the real-time sensing and perception of their surrounding environment. The current sensing technologies facilitate the broad application of various field sensors such as cameras, LIDAR/RADAR, ultrasonic sensors, etc. However, due to the nature of field perception and measurements performed by these sensing devices, which essentially is an infinite-dimension problem in space, huge challenges are posed for effective and efficient applications of them, especially, when applied in autonomous operations which normally demand tremendous robustness of performance. Another major concern in practices about field sensing devices is the cost of devices themselves, whereas the realities in autonomous operations call for solutions of networked low-cost sensing units instead of powerful single or multiple high-cost units. Apparently, it would be of great significance for both research and industrial applications to dig out the greatest potential of field sensing and perception as applied in various autonomous operations (for example, autonomous operation of ground or aerial robotic vehicles) so that these operations could be delivered in a way that is both the most effective and the most cost efficient. This research proposal intends to address the distributed optimization for field sensing networks with the operation of autonomous robotic vehicles being the showcase of application. It is noted that the focus will be on developing a systematic design framework which will be featured with novel modeling thinking, new concepts of problem formulation, practically feasible design procedures and algorithms, and meaningful applications to autonomous robotic operation tasks. In particular, it is expected that the sensing functions and robotic vehicle operations are integrated to generate conceptually new methods to address the said problems and to design robust and optimal control and management mechanisms for the networked autonomous robotic vehicles. It is also argued that the framework developed would be highly industrial-practices oriented and hence would find its way to be easily applied in practices.

地面或空中的自主机器人车辆在我们当前和未来生活中看到或期望的各种智能操作中发挥着关键作用，从家庭服务和工业制造，到越来越多的现场应用，例如自然资源监测、管道和建筑检查、精准农业、矿产勘探、搜救行动等。由于功能预期日益复杂，毫无疑问，自主机器人车辆的网络化和协作操作将受到很高的需求。众所周知，自动驾驶汽车面临的最大挑战之一是对其周围环境的实时感知和感知。当前的传感技术促进了各种现场传感器的广泛应用，例如摄像头、激光雷达/雷达、超声波传感器等。然而，由于这些传感设备执行的场感知和测量的性质，这本质上是一个无限维问题在太空中，它们的有效和高效应用面临着巨大的挑战，特别是当应用于通常需要巨大性能鲁棒性的自主操作时。现场传感设备实践中的另一个主要问题是设备本身的成本，而自主操作的现实需要联网的低成本传感单元的解决方案，而不是强大的单个或多个高成本单元。显然，挖掘场感测和感知在各种自主操作（例如地面或空中机器人车辆的自主操作）中的最大潜力，使这些操作能够被应用到研究和工业应用中都具有重要意义。以最有效且最具成本效益的方式交付。该研究提案旨在解决现场传感网络的分布式优化问题，以自动机器人车辆的操作作为应用展示。值得注意的是，重点是开发一个系统的设计框架，该框架将具有新颖的建模思维、新的问题表述概念、切实可行的设计程序和算法以及对自主机器人操作任务的有意义的应用。特别是，期望将传感功能和机器人车辆操作相集成，以产生概念上的新方法来解决上述问题，并为网络自主机器人车辆设计稳健且最优的控制和管理机制。还有人认为，所开发的框架将高度面向工业实践，因此将找到易于在实践中应用的方法。
