The limits of robotic solutions to human challenges in the land domain

In the face of rapid technological change and the creation of ambitious military modernisation programmes, this paper argues that land forces, in managing the relationship between force levels and the adoption of military robotics, must recognise that there are inherent limits to techno-centric force reduction efforts and realise the inefficacy of substituting skilled soldiers with robots. It begins with an overview of how the proper integration of robotics into a military’s force structure can improve capability, save lives and potentially reduce costs, but suggests that common accounts of robot utility are exaggerated and endanger the risk assessment processes governing the adoption of said technologies and relevant personnel settings. The paper explores the limits of robotic solutions to military problems, discussing their technical limitations, redundancy and related issues that, when combined with a technico-moral skills degradation problem also detailed within, point to the need to reshape force structures to suit the adoption of robotics while preserving existing levels of human staffing.     

信号时序逻辑约束下基于终点回溯的高效规划

在信号时序逻辑约束下规划路径是一项具有挑战性的任务,其计算量非常高。提出了一种终点回溯的规划方法,它是一种适用于连续时间系统的抽象化方法。该规划方法分为离线构建阶段和在线规划阶段。离线构建阶段在Transducer理论的指导下,从能够完成任务的合理的终点构造一棵快速随机搜索树,向初始状态空间进行回溯。当采样点足够多时,在线规划阶段使用模型预测控制将机器人驱动到快速随机搜索树的叶子节点。通过所提出的规划方法,避免了环境的有限转移系统与信号时序逻辑对应的自动机乘积引起的状态空间爆炸问题。所提出的方法将在线路径规划所需时间降低到1s以下,充分说明了本方法的有效性。与混合整数线性规划以及贝叶斯优化方法相比较,所提出的终点回溯规划方法在线求解效率更优,且更加易于扩展至多机器人协同工作场景。
