In this paper, the modeling and planning problems of a system composed of multiple ground and aerial robots involved in a transportation task are considered. The ground robots rigidly grasp a load, while the aerial vehicles are attached to the object through non-rigid inextensible cables. The idea behind such a heterogeneous multi-robot system is to benefit of the advantages of both types of robots that might be the precision of ground robots and the high pay-load of multiple aerial vehicles. The overall model of the system is derived and its expression and redundancy are exploited by setting a general constrained optimal planning problem. The problem is herein solved by dynamic programming and simulation results validated the proposed scheme.
在本文中，考虑了由运输任务中涉及的多个地面和空中机器人组成的系统的建模和规划问题。地面机器人严格地抓住负载，而飞行器通过非刚性不可伸展的电缆连接到物体上。这种异构多机器人系统背后的想法是受益于两种类型的机器人的优点，这些机器人可能是地面机器人的精确度和多个飞行器的高工资负荷。通过设置一般约束最优规划问题，导出系统的整体模型，并利用其表达和冗余。该问题在此通过动态编程解决，并且仿真结果验证了所提出的方案。

本文旨在为由无人机和UGV组成的异构团队合作运输负载奠定基础。无人机通过不可伸展的电缆连接到负载上，并可以自由地浮在物体上的电缆连接点周围。这种冗余与系统模型一起被利用来设置考虑若干目标的最优规划问题，如无人机和UGV之间的负载分布以及可由无人机生成的可行扳手的空间。
