Reference
setMotorModel(data1,data2,data3,data4)
This function has four input parameters that control the left front motor, the left rear motor, the right front
motor, and the right rear motor. When the input parameter is within 0~4096, the motor will rotate forward.
If it is within -4096~0, the motor will rotate reversely. The larger the absolute value is, the faster the motor
is. When the input is 0, the motor will stop. If the function is input as follows: setMotorModel(2000,2000,
2000, 2000), four motors will rotate forward and the car will move forward.
