    Abstract: A device (11) for simulating a behaviour of a mammal in an environment (2) by a Virtual mammal (1 ) includes a mobile (5) head (3) and at least one mobile (6) eye (4). The device comprises a first input for successive data representative of eye poses, a second input for mobility action instructions (9), a memory (13) for storing information on the environment (8) and on stabilization constraints (7), at least one processor (12) configured for assessing a current part of the environment (2) and recording information (8) on said current part, triggering successive movements (5) of the head and of the eye(s) in function of said mobility action, the successive data and the stored information on the environment, controlling a dynamic adjustment of the successive movements of the eye(s) with respect to the successive movements of the head in function of the successive data and by using the stabilization constraints. The device further comprises a third input for training data (23) representative of a training movement sequence of the head and the eye(s) associated with a training environment, the processor(s) learning in a training stage the stabilization constraints through triggering in the training environment successive movements (5) of the head corresponding to said training movement sequence, assessing a current part of the training environment from the training data and recording information on said current part (8'), so that the Virtual mammal provides a simulated behaviour of the mammal to be simulated.
