摘要翻译：
路径整合使沙漠节肢动物能够从任何位置以最短的轨迹找到回巢。为了成功地进行路径积分，必须连续测量沿前一出站路径的速度和转弯角，并将其组合以确定在任何时候引导回家的内部{\em全局向量}。许多实验已经给出了节肢动物如何使用异体或特异性信号来感知它们的方位和移动速度的概念。我们系统地回顾了数学精确路径积分的四种可能的模型描述，由此我们支持并阐述了迄今为止尚未使用的以自我为中心的笛卡尔坐标的变体。通过与其它模型的比较，证明了该模型结构简单直观。测量两种速度，前进速度和转角速度，并将其化为线性微分方程组，提供了出站路线、重新定向过程和返回路径所需的信息。此外，我们还提出了几种可能导致偏离正确回家路线的系统误差类型。在不同的实验中观察到了几种沙漠节肢动物的偏差，但它们的起源仍有争议。利用我们的自我中心路径集成模型，我们提出了简单的误差指数依赖于路径几何，这将允许未来的实验排除或证实某些错误类型。

英文摘要：
  Path integration enables desert arthropods to find back to their nest on the shortest track from any position. To perform path integration successfully, speeds and turning angles along the preceding outbound path have to be measured continuously and combined to determine an internal {\em global vector} leading back home at any time. A number of experiments have given an idea how arthropods might use allothetic or idiothetic signals to perceive their orientation and moving speed. We systematically review the four possible model descriptions of mathematically precise path integration, whereby we favour and elaborate the hitherto not used variant of egocentric cartesian coordinates. Its simple and intuitive structure is demonstrated in comparison to the other models. Measuring two speeds, the forward moving speed and the angular turning rate, and implementing them into a linear system of differential equations provides the necessary information during outbound route, reorientation process and return path. In addition, we propose several possible types of systematic errors that can cause deviations from the correct homeward course. Deviations have been observed for several species of desert arthropods in different experiments, but their origin is still under debate. Using our egocentric path integration model we propose simple error indices depending on path geometry that will allow future experiments to rule out or corroborate certain error types.
