ABSTRACT
This study focuses on the development of a dynamic mathematical model for a remotely controlled mobile robot chassis prototype, built at Kaunas College, and presents an experimental analysis of its 18V DC motor dynamic parameters. The methodology combines the mathematical modelling of chassis motion with experimental testing of motor behavior under both no-load and full-load conditions. The experimental results reveal a significant difference in motor requirements between operating states. Specifically, overcoming static friction under load requires a start-up voltage of 5.51 V and a current of 6 A, corresponding to 33.06 W of power. The developed dynamic model, validated by the obtained experimental data, allows for a more accurate prediction of the robot’s motion trajectory and provides crucial insights into the motor power requirements necessary for stable initiation of movement under loaded conditions.
