CHALET: Cornell House Agent Learning Environment
  We present CHALET, a 3D house simulator with support for navigation and
manipulation. CHALET includes 58 rooms and 10 house configuration, and allows
to easily create new house and room layouts. CHALET supports a range of common
household activities, including moving objects, toggling appliances, and
placing objects inside closeable containers. The environment and actions
available are designed to create a challenging domain to train and evaluate
autonomous agents, including for tasks that combine language, vision, and
planning in a dynamic environment.
