If you don't have access to proper miniature gear box you can try to drive a rubber belt (see picture below) between the motor's shaft and a dummy wheel attached to the robot's wheel .. You will gain as much toque and reduce speed as is the ratio between diameters of the motor's shaft and the dummy wheel ..
