基于室内四轴飞行器的多智能体路径搜索计划执行
Plan Execution for Multi-Agent Path Finding with Indoor Quadcopters
摘要:
本文研究了多智能体路径搜索问题的规划和行动阶段。MAPF是一个导航代理从他们的开始位置到指定的个人目标位置,使代理不相互碰撞的问题。具体来说,我们专注于执行MAPF计划与一组Crazyflies,小型室内四轴飞行器。我们展示了如何修改现有的连续时间基于冲突的搜索算法(CCBS),以产生适合于执行的四轴飞行器的计划。行动阶段使用Loco定位系统来检查计划是否正确执行。我们的发现是,CCBS算法允许扩展,可以产生安全的四轴飞行器的计划,即圆柱形保护区周围的每个四轴飞行器可以在规划水平。
英文摘要:
We study the planning and acting phase for the problem of multi-agent path finding (MAPF) in this paper. MAPF is a problem of navigating agents from their start positions to specified individual goal positions so that agents do not collide with each other. Specifically we focus on executing MAPF plans with a group of Crazyflies, small indoor quadcopters . We show how to modify the existing continuous time conflict-based search algorithm (CCBS) to produce plans that are suitable for execution with the quadcopters. The acting phase uses the the Loco positioning system to check if the plan is executed correctly. Our finding is that the CCBS algorithm allows for extensions that can produce safe plans for quadcopters, namely cylindrical protection zone around each quadcopter can be introduced at the planning level.
