All u need is a good mechanical set up to fir ur motor gear with the module. u can even make a two wheel robot which is easy to steer... try for it... just controll the motor. make the two motors synchronous so that there is no mismatch then u are ready with a two wheeled robot. u may interface sensors for developing ur robot. www.migindia.com there are lot of resources for making the 2 wheel robot.. u may write ur own codes..
