基于态势演算的机器人位置估计

Robot Location Estimation in the Situation Calculus

University of Toronto(多伦多大学)

Vaishak Belle, Hector Levesque

摘要:

位置估计是机器人应用中的基本传感任务,其中世界是不确定的,并且传感器和执行器是有噪声的。大多数系统对状态变量之间的依赖关系做出各种假设,特别是关于这些依赖关系如何作为操作的结果而改变。本文基于巴克斯、哈尔彭和莱维斯克关于情境演算中置信度推理的一般框架,以及最近对连续域的扩展,我们使用一个例子说明了在存在丰富的行动理论的情况下的位置估计。我们还表明,虽然行动可能会影响先验分布在非标准的方式,适当的后验信念,但作为一个整体规范的副作用。

英文摘要:

Location estimation is a fundamental sensing task in robotic applications, where the world is uncertain, and sensors and effectors are noisy. Most systems make various assumptions about the dependencies between state variables, and especially about how these dependencies change as a result of actions. Building on a general framework by Bacchus, Halpern and Levesque for reasoning about degrees of belief in the situation calculus, and a recent extension to it for continuous domains, in this paper we illustrate location estimation in the presence of a rich theory of actions using an example. We also show that while actions might affect prior distributions in nonstandard ways, suitable posterior beliefs are nonetheless entailed as a side-effect of the overall specification.
