My robot is not running on the battery power. The condition right now is that there is 4.8V going into the 9V jack next to the programming jack. When I turn on the Arduino board on battery power, the power LED turns on, on both boards, motor drive shield(L293D) and the main Arduino board. Also, I can see the transmitting led blinking as two motors move like 1 degree and stop. When the motor moves, it just sounds like a clock ticking.
Please help me with this problem

I wonder if that's a clue.....

(Not that it's a 9V jack actually, it's a 7-12V jack)

Which means that the minimum input voltage is 7V.
