Jim jumped forward, throwing himself as hard as he could at the dumpster thrown his way. The path was altered enough that it did not hit the house. Then, Jim jumped out of it and threw it back at the other robot. When this was done, he jumped back to the roof and retrieved his gun from Kate, who had taken it when he jumped the first time.
