In this paper, we propose a new mothod using the PID controller gain value from rotatation of wheels according to rotation momentum characteristics for an educational mobile robot. P-Gain, I-gain and D-gain have been changed from the mobile robot via wireless remote control in a real-time basis. The transmitted gain value is calculated by real-time operation of embedded software in the robot. Experiments are carried out to find the optimized gain value of two conditions, maximum speed and minimum speed. The gain of intermediate velocity region is calculated from this gain value using primary curve fitting. The intermediate region gain value is calculated by real-time transmission of the mobile robot. Successful results are demonstrated with PID control using the calculated intermediate region gain value.
