W artykule przedstawiono możliwości odbywania podróży zagranicznych przez studentów uczestniczących w międzynarodowych konkursach, w szczególności w zawodach robotycznych, popularnych między innymi ...wśród polskich studentów. Jak pokazują zebrane dane zawody te przyciągnęły nawet kilka tysięcy uczestników w ciągu ostatnich lat. Zaprezentowany został dodatkowy efekt ich uczestnictwa w konkursach, jakim jest turystyka uprawiana w trakcie takich wyjazdów i nazwana przez autorów turystyką konkursową.
The article presents opportunities for foreign travel by students based on trips to international competitions, in particular robotic competitions. As the data collected show, these have attracted ...several thousand participants in recent years. The article presents an additional effect of participation in such competitions which is tourism during the trips.
A detailed literature analysis depicts that artificial neural networks are rarely used for the power consumption estimation in the mobile robotics field. Instead, researchers prefer to develop ...analytical models of investigated robots. This manuscript presents a comparison of mathematical models and non-complex artificial neural networks in energy prediction tasks for differential and skid-steer drive robots which move over various types of surfaces. The results show that both methods could be used interchangeably but AI methods are more universal, do not depend on the kinematic structure of a robot and are tolerant for designers not having a complex knowledge about the system.

This paper presents application of the Navigation Stack available in Robot Operating System as a basis for the autonomous control of the mobile robots developed for a few different robot ...competitions. We present three case studies.
Wheel slippage is mostly an unwanted but sometimes inevitable disturbance, especially in mobile robots with over-constrained suspension or operating on slippery surfaces. Improving odometry alone can ...increase overall localization accuracy, especially when other sources of position information are unavailable. There are several publications dealing with slippage detection and odometry correction, however, they are mostly related to identification of surface for single specific robot type and they require external measurement system for tests. This paper presents a methodology and experiment comparing slip-compensated odometry and tries to extrapolate it to three different suspensions. The main idea behind this article was to check, if different mechanical suspensions with the same kinematic structure (skid-steering), could achieve similar localization accuracy according to the same slip compensation method and using only onboard sensors. The research platform was a custom modular robot. Its chassis allows it to swap the suspension to skid steer six- and four-wheel and tracks. Four chapters of the paper are are organized as follows: in the Introduction, the problem is described in mathematical formulas, then the experiment setup, process and a method for calculating an algorithm-specific coefficient are discussed, followed by presentation of results and summary.
