Method Detail

getRotationSpeed

int getRotationSpeed()

Returns the actual speed. This value is calculated every 100 ms on the NXT. TODO: getRotationSpeed() is an alternate method name, but then we are again competing with Motor.getSpeed()

Returns:

speed in degrees per second, negative value means motor is rotating backward
