Observation Space Interpretation

I think you'll have to extract them from self.grid in the warehouse class. Apologies, but I don't have the time capacity to assist with that. The _make_obs function might be a good starting point though:

This is a good start to understanding it: https://github.com/semitable/robotic-warehouse/blob/master/rware/warehouse.py#L404

you can even use the "slow" observations (observation type DICT) that you can then probe as a dictionary. See here:

@semitable Thank you for the help.

I still dont get it what the sensor range means. Basically it is the range of the agent. But if the sensor_range is 1 it means that the agent has the informations about the cell above,right,left and above?

Btw how could we extract the positions of the requested shelfs?

[semitable]

If sensor range is 1, then the agent can see everything inside a 3x3 box centred around it, i.e. the directions you mention plus the diagonal ones.
For a sensor range of 2 it's a 5x5 box centred around it.

You mean the absolute positions? For that you might have to dig into the code as the absolute position of shelves is not provided in the observation vector.

Yes, I was asking for the absolute positions. Where can i find them to return them on the observation space?

Thank you! I finally manage to extract the absolute positions of the requested shelfs in the observation space.

P.S: I have changed the original grid from my initial comment. Here is the actual grid:
