Robot: Save Life

In the near future, after a meteorite fell to the ground, the air was infected with a dangerous virus on it. He literally in a few days destroyed all life on the planet, and only a certain part of humanity survived hiding in bunkers with robots supporting life support. Your task as a robot:
support yourself
life support of the bunker during the night, as well as reset the counter by entering the password into the computer within 140 seconds.

Well! Good luck!
