The paper presents the methodology and implementation of experimental research on a pneumatic hub system attached to the rim of a platform with pneumatic wheels. The objective of the research was defined as determining the suitability of the proposed solution for real-time air pressure modification in the wheel to increase the mobility of the wheeled platform in undetermined terrain. The paper includes drawings illustrating the necessary components of the pneumatic system associated with the platform’s pneumatic wheel. The final conclusions indicate the correctness of the adopted concept and research methodology.Commonly used wheeled platform solutions for mechatronic vehicles such as mobile robots may not ensure the complete execution of a task by the vehicle due to, for example, obstacles encountered on the robot’s path.
This is because, for undetermined terrain (i.e., an area of robot operation with unknown surface characteristics), existing wheeled platform solutions do not guarantee proper adaptation of such chassis to the encountered driving conditions. Works [2], [4], and [8] point out the reasons for this state of affairs and propose a solution to improve the driving parameters for platforms with pneumatic wheels on which mechatronic equipment can be installed.
