Use Infrared sensors to detect the revolutions of the motors per minute, this may be of help to you

my micro mouse kit has a very thin wheel compared to the above link....what u think i can do in that case???

i suggest hall effect sensor. You need to attach a small magnet in the wheel of your micromouse.

could you please give me more details on this way ?

hall effect sensor is a magnetic sensor. Two type of sensors are awailable. One is a switch. Another is analog . I think switch is more usefull for you . In switch sensor when an north pole comes near the sensor it get activated. And when south pole, deactivated.
