H-bridge Power

Tonight we found out the h-bridge does not have enough power to power to the d/c motor when there is any kind of friction like the ground. We are going to investigate this farther. When the wheel is in the air week get 3+V going to DC motor. When on ground in the beginning there at 150mV. We connected a 9v battery directly to the d/c motor and the car moved instantaneously. We test the other h-bridge again. It was lacking voltage power to drive the motor as well. We know it is power issue with the h-bridge. Our h-bridge powers our 3 sensors as well. We disconnect them hoping it would have an impact. Test failed, still could not move in the beginning by itself.
