Scrap Mechanic has preset places on the map called POIs (Points Of Interest), each one can either be a warehouse or a burnt forest with farmbots. They generate in a grid like pattern (as you can see in the image).

The closest one to spawn is straight ahead, which is why you always see speedrunners in any% or farmbot% go in the same direction in their runs

You might have to reset a couple of times though to get the necessary items as well as the right tile (2 story warehouse or burnt forest, depending on the category you're running) at the closest spot.

This Guide is intended for Chapter 1 of the game, we don't know if or what will change with Chapter 2.
