Abstract: We propose a new approach to the simultaneous cooperative localization of a group of robots
capable of sensing their own motion and the relative position of nearby robots. In the last decade, the use
of distributed optimal Kalman filters (KF) to solve this problem have been studied extensively. In this
paper, we propose to use a sub-optimal Kalman filter (denoted by EA). EA requires significantly less
computation and communication resources then KF. Furthermore, in some cases, EA provides better
localization.
In this paper EA is analyzed in a soft “thermodynamic” fashion i.e. relaxing assumptions are used during
the analysis. The goal is not to derive hard lower or upper bounds but rather to characterize the robots
expected behavior. In particular, to predict the expected localization error. The predictions were validated
using simulations. We believe that this kind of analysis can be beneficial in many other cases.
