摘要:

在测量或监控偏远地区等任务中,自主机器人必须移动,同时通过无线网络以未知的位置相关传输速率传输数据。对于这样的机器人,本文考虑的问题,在最短的时间内传输数据缓冲区,同时也可能朝着目标位置导航。提出了两种方法,每一种方法包括一个机器学习组件,估计从样本的速率函数;和一个最优控制组件,移动机器人给定的当前速率函数估计。对于没有目标位置的情况,执行简单的避障。在广泛的模拟,这些方法实现了竞争力的性能相比,已知的速率和未知的速率基线。提供了一个真实的室内实验,其中Parrot AR.Drone 2成功地学习传输缓冲区。

英文摘要:

In tasks such as surveying or monitoring remote regions, an autonomous robot must move while transmitting data over a wireless network with unknown, position-dependent transmission rates. For such a robot, this paper considers the problem of transmitting a data buffer in minimum time, while possibly also navigating towards a goal position. Two approaches are proposed, each consisting of a machine-learning component that estimates the rate function from samples; and of an optimal-control component that moves the robot given the current rate function estimate. Simple obstacle avoidance is performed for the case without a goal position. In extensive simulations, these methods achieve competitive performance compared to known-rate and unknown-rate baselines. A real indoor experiment is provided in which a Parrot AR.Drone 2 successfully learns to transmit the buffer.
