The paper considers the architecture of mobile autonomous systems, which is flexible with respect
to the task. Basically, the architecture of all mobile autonomous systems is the same, but it has the ability to vary its
content by removing or adding certain parts. Mobile autonomous systems can be called mobile robots, because the word
robot has already firmly established itself in everyday life. The main parts of the architecture of a mobile robot are
definitely its control unit, which performs all the calculations and makes decisions, the wheelbase, which is responsible
for transporting the robot to a given point, and the power unit, which provides power to the robot. The purpose and
objectives of the mobile robot will show the use of such parts as a sensor unit designed to receive and collect data from
the environment, and a payload unit necessary for conducting, for example, scientific research. The paper provides an
overview of each module of the architecture of mobile robots: control unit, wheelbase, sensor unit, power unit and payload unit. This allows you to understand which type of each module is suitable for a particular task and shows the
variety of existing types, which provides ample opportunities for creating a mobile robot with the necessary parameters.
