摘要:

在搜索和救援环境中导航是具有挑战性的,因为必须考虑各种地形。由我们的机器人Momaro提供的混合驱动-步进运动是一种很有前途的方法。与其他运动方法类似,它包含许多自由度-提供高灵活性,但使规划计算昂贵的大型环境。我们提出了一种导航规划方法,它统一了不同层次的表示在一个单一的计划。在机器人附近,它提供了具有精细分辨率和高机器人状态维度的计划。随着与机器人的距离增加,计划变得粗糙,机器人状态维数降低。我们弥补这种损失的信息丰富粗糙表示额外的语义。实验表明,该规划器提供了计划,在可行的时间大,具有挑战性的情况下。

英文摘要:

Navigating in search and rescue environments is challenging, since a variety of terrains has to be considered. Hybrid driving-stepping locomotion, as provided by our robot Momaro, is a promising approach. Similar to other locomotion methods, it incorporates many degrees of freedom---offering high flexibility but making planning computationally expensive for larger environments. We propose a navigation planning method, which unifies different levels of representation in a single planner. In the vicinity of the robot, it provides plans with a fine resolution and a high robot state dimensionality. With increasing distance from the robot, plans become coarser and the robot state dimensionality decreases. We compensate this loss of information by enriching coarser representations with additional semantics. Experiments show that the proposed planner provides plans for large, challenging scenarios in feasible time.
