基于雁阵变换的微型扑翼飞行机器人集群行为控制方法

为了解决微型扑翼飞行机器人集群编队目标搜索覆盖效率、避障通过性和多机控制等难题,实现扑翼飞行机器人集群编队的智能控制,提出了基于雁阵变换的扑翼飞行机器人集群行为控制方法。利用仿生集群行为控制函数的参数化特性,实现了飞行机器人编队的队形变换和角度控制;搭建了多扑翼飞行机器人实验系统,并在多种情况下设计基于仿生行为的多扑翼飞行机器人集群控制方法实验。最终的实验结果验证了方法的可行性和有效性。与传统的多飞行机器人实时控制方法相比,所提方法大幅提升了集群编队的搜索覆盖效率和避障通过率,在某些作业环境条件下,搜索覆盖率可提升50%以上,障碍通过率可提升60%以上。同时,创新点体现在将雁阵变换应用于多扑翼飞行机器人集群编队控制和将仿生集群行为控制应用于扑翼飞行机器人集群控制两个方面。

基于虚拟现实和眼动追踪的人-集群机器人交互方法

操作员对集群机器人实施远程控制时面临被控对象众多、群体态势感知困难、集体行为控制不易等诸多挑战,使得手动遥控等传统交互方式无法实现高效、灵活、强沉浸感的人-集群机器人交互。为此,提出一种基于虚拟现实(VR)和眼动追踪的人-集群机器人交互(HSI)方法。首先,构建集群机器人VR交互场景并采集操作员的眼动数据;其次,解析获得瞳孔坐标、注视点等眼动特征,据此生成集群机器人的运动控制指令;最后,开展了真实集群机器人集群漫游、集群目标追踪及集群轨迹跟踪交互实验。机器人实验结果表明,该方法可实现灵活、便捷的人-集群机器人远程交互控制,这为人与集群机器人的共融协作提供了一种新的途径。

Multi-boid Flocking with Formation Control Using Local Sensing and Communication

Behavior-based flocking has got remarkable attention in the recent past. The flocking algorithms can have inherent properties like organizing,healing and re-configuring for a distributed system. In this research we presented the emergent flocking behavior-based control. We defined the basis behavior and with variety of combination, and obtained a complex group behavior flocking. Unlike classical flocking, we implemented additional rules obstacle avoidance,formation and seek target which results in V-formation flocking while avoiding obstacles. We performed the visual simulation of our flocking algorithm using MATLAB. The results concluded that the multi-boid flock could successfully navigate to the target while avoiding collisions. This can be applied to areas where we need to maximize the coverage of sensors or minimize the risk of combative attack,both in military and civilian scenarios.
