There are a total 120 scenes in version 1.0 of the THOR environment covering four different room categories: kitchens, living rooms, bedrooms, and bathrooms. Each room has a set of objects that can be found in it. Note that some Object Types are guaranteed to be found in all scenes of a given category, while some are only sometimes found in scenes of a category. See the Object Types section for more Object Type information.

During scene initialization, objects can be placed on different receptacles so we can obtain many different configurations for a single scene. Hence, the number of configurations is much larger than 120.
