Okay, a bit more detailed: you'll need to head south and find the general store (it's just west of the path and one of the first locations you'll find. Once you enter the store, you can find a key to a locked store room in the store, and some oil from the store room. After this the robot will enable you to progress to the South East and then ultimately, to the North.
