When I got to the part when I have to escape,I dropped down the chute to where there are 4 arms sorting out the destroyed parts. Then I jumped on one of the treadmill where there's the sword from the robot I just killed on it. I then glitched through and fell into a hole and the sword is there too.

Thanks for the report! Yes, that's a really silly thing that the game doesn't stop you from doing. :)
