Abstract
In this work we analyze robot motion given from the UTIAS
Multi-Robot Dataset. The dataset contains recordings of robots wandering in a confined environment with randomly spaced static landmarks.
After some preprocessing of the data, an algorithm based on the Extended Kalman Filter is developed to determine the positions of robots
at every instant of time using the positions of the landmarks. The algorithm takes into account the asynchronous time steps and the sparse
measurement data to develop its estimates. These estimates are then
compared with the groundtruth data provided in the same dataset. Furthermore several methods of noise estimation are tested, which improve
the error of the estimate for some robots
