CHALET: Cornell House Agent Learning Environment

CHALET is a 3D house simulator with support for navigation and manipulation. Unlike existing systems, CHALET supports both a wide range of object manipulation, as well as supporting complex environemnt layouts consisting of multiple rooms. The range of object manipulations includes the ability to pick up and place objects, toggle the state of objects like taps or televesions, open or close containers, and insert or remove objects from these containers. In addition, the simulator comes with 58 rooms that can be combined to create houses, including 10 default house layouts. CHALET is therefore suitable for setting up challenging environments for various AI tasks that require complex language understanding and planning, such as navigation, manipulation, instruction following, and interactive question answering.

Release

CHALET Version 0.1 is available for download at: http://clic.nlp.cornell.edu/resources/CHALET/

An unstable version of the CHALET source code is now available.

Please see the Wiki for details on how to use these builds and the source code.

For support and issues, please contact us through the issues section of the repository.

Source Code

The CHALET source code is released without proprietary assets purcahsed from the Unity Asset Store. These assets are required to work with the original source, but not with the released binaries. We extensively modified the resources for CHALET. If you wish to work with the source code, please contact us (chalet-3d@googlegroups.com) for instruction on obtaining the required resources. See more details in the wiki.
