AI 中文摘要
我们提出了动态旋转堆叠可见性图(dRVG),一种在线运动规划器,能够在初始未知的静态环境中引导多边形机器人到达指定目标。它融合来自连续观测的局部路标图,以规划无碰撞的平移和旋转,而无需均匀位置网格。空间四叉树在区域间调度感知目标,以减少重复访问,同时保留所有用于路由的取向配置。在精确感知和几何计算以及星形机器人和包络假设下,使用中心扫描的dRVG相对于相同角分辨率下的全图RVG是分辨率完备的。在使用足迹扫描的实验中,dRVG在20秒规划预算内解决了20个困难地图和七个角分辨率下的全部140个案例,在360个取向层的中位规划时间为1.18秒。六个microMVP演示展示了物理机器人上的完整在线规划循环。
英文摘要
We present the dynamic rotation-stacked visibility graph (dRVG), an online motion planner that guides polygonal robots to specified goals in initially unknown, static environ- ments. It merges local roadmaps from successive observations to plan collision-free translations and rotations without a uniform position grid. A spatial quadtree schedules sensing goals across regions to reduce repeated visits while retaining all orientation configurations for routing. Under exact sensing and geometric computation and star-shaped robot and envelope assumptions, dRVG with center scans is resolution-complete relative to full- map RVG at the same angular resolution. In experiments using footprint scans, dRVG solves all 140 cases across 20 difficult maps and seven angular resolutions within a 20 s planning budget, with a median planning time of 1.18 s at 360 orientation layers. Six microMVP demonstrations illustrate the complete online planning loop on a physical robot.
