You search around for something to make a gun out of. However, there are no tubes or intricate mechanical parts that you could make a gun out of. And anyway, wouldn't a gun require some kind of explosive propellant?
Instead, you find a heavy leg that could be used as a club.
For armor, you grab a few metal plates and fasten them around your chest as best you can.
Perhaps if you had a heat source, you could heat the metal until it was more flexible, then make something more useful out of it?
The only body parts that seem similar to hands around you are feet. You grab/rip off a few feet from the surrounding wreckage and insert it into the robots' arm stubs.
You notice that the intact robots' bodies glow slightly where you touch them.
